Looking for the best Mazda RX-7 suspension? Well, whatever the type of build you\u2019re going for, we\u2019ve got you covered.<\/strong><\/p>\n

When it comes to aftermarket suspension, it\u2019s not simply a case of \u2018one size fits all\u2019. Instead, you\u2019ll want to opt for a different set-up depending upon two things: A, which generation of Mazda RX-7 you own, and B, what your tuning goals are. So, without further ado, here\u2019s the best Mazda RX-7 suspension that the aftermarket has to offer.<\/p>\n

If you don’t own an RX-7 but are looking to upgrade the running gear of your own car, be sure to check out our guide to the best car suspension in 2023<\/a>.<\/em><\/p>\n

Best Suspension for Mazda RX-7 (FC)<\/h2>\n

What\u2019s it like as Standard?<\/h3>\n

Although still a fun car to drive, the second gen \u2018FC\u2019<\/a> is arguably the least athletic RX-7 in its factory guise.<\/p>\n

Aimed primarily at the American market, Mazda designed the FC to be more of a GT cruiser than a true B-Road specialist. As a result, it came with a number of suspension revisions compared to the original SA22 RX-7, though they weren\u2019t to everyone\u2019s liking.<\/p>\n

The headline piece of tech was Mazda\u2019s Dynamic Tracking Suspension System (DTSS), which adjusts the toe angle at each wheel depending on cornering force. The intention was to improve stability, though as a knock-on effect, it does reduce the amount of feel and feedback sent back to the driver.<\/p>\n

Similarly, Auto Adjusting Suspension (AAS) was another new feature on the FC. This tech alters the damper settings in line with the road surface for an improved ride, but like DTSS, it also numbs the driving experience.<\/p>\n

It wasn\u2019t all bad news though. The original SA22 RX-7 had quite a twitchy rear end, but that was largely corrected in time for the FC by swapping its live axle for an independent rear suspension set-up instead.<\/p>\n

\"Rear<\/p>\n

The Best Street Suspension for a Mazda RX-7 FC<\/h3>\n

If you want the best results from a suspension upgrade, we\u2019d suggest opting for a set of coilovers<\/a> rather than lowering springs \u2013 if you\u2019ve got the budget for it. This is because as well as getting that lower ride height, coilovers also present you with much more adjustability to get the balance right between comfort and performance. Whereas, with lowering springs, you\u2019re locked into a firmer spring rate. It\u2019s also worth noting that coilovers come with a spring rate that\u2019s matched to the dampers as, after all, you\u2019re buying the full package in one kit. With lowering springs, that\u2019s not the case, and as result your ride quality may suffer.<\/p>\n

The Best Coilover Options<\/h3>\n

One of the top coilover kits out there for the Mazda RX-7 FC is the ISR Performance Pro Series. These come with 32-way adjustable damping, a monotube design, and front pillowball mounts. ISR deemed its previous \u2018basic\u2019 coilover kit good enough for Formula Drift, but these Pro Series examples are a technological step up from those, suitable for both street and track use. You can order them direct from ISR<\/a> for $925 (\u00a3756), though some online retailers sell them at a higher premium.<\/p>\n

If you aren\u2019t keen on ISRs, BC Racing is another hugely reputable brand that provide aftermarket coilovers for the FC. The entry-level BR kit is more capable than its pegging within BC Racing\u2019s product hierarchy suggests, and as such costs a little bit more than the ISRs. You\u2019re probably also paying a bit more for the brand name. You\u2019ll have to spend $1284 (\u00a31049) on the BR series kit<\/a>, but as far as coilovers go, that\u2019s still within the reasonably affordable bracket.<\/p>\n

Our final top pick for street use is the HSD Monopro. They retail for $1024 (\u00a3845), however you can often pick them up for a bit less than that in a sale. At the time of writing, HSD<\/a> will sell them to you directly for a reduced rate of $930 (\u00a3760). However, it\u2019s worth noting that these HSDs only offer 16-stage damping adjustment, which is about half the amount of adjustment you get with either the ISR or BC Racing kits mentioned above.<\/p>\n

\"Pandem<\/p>\n

The Best Circuit Suspension for a Mazda RX-7 FC<\/h3>\n

What if your FC RX-7 is a more specialized build though? A car destined for circuit use only, perhaps. Well, happily there\u2019s plenty of hardcore performance-oriented coilover kits on the market that place less emphasis on road comfort for the sake of all-out handling gains on the track.<\/p>\n

An example of the top end of this genre is Yellow Speed Racings\u2019s Advanced Pro Plus kit. You can get them with either a 3-way ($3551\/\u00a32902)<\/a> or 2-way ($2873\/\u00a32348)<\/a> design, where the 3-way option adds the ability to adjust high-speed rebound (how quickly the vehicle rises after hitting a bump).<\/p>\n

If you can\u2019t quite make your budget stretch that far, D2 Racing will hook you up with some circuit-tailored coilovers<\/a> for $1510 (\u00a31234) instead. Don\u2019t think the reduction in price is a sign that they\u2019re no good either. D2 claims that this kit has been used to achieve more than 250 race victories at grassroots level, and they offer an impressive 36 stages of damping adjustment.<\/p>\n

Suspension for Drifting and Drag Racing<\/h3>\n

But what if you don\u2019t what to do track days or time attacks? Well, KSport\u2019s got you covered. They\u2019ll sell you coilover kits for the FC RX-7 designed for either road rallies or drag racing<\/a>, each kit costing $1900 (\u00a31553) to buy. Or, if you prefer going sideways, you can grab some drift-focused coilovers<\/a> from them for $2050 (\u00a31675).<\/p>\n

TEIN also provide a drift coilover kit for the RX-7 at a slightly more affordable price ($1790\/\u00a31463). They come with 16-way adjustability, a twin-tube structure, pillowball upper mounts, and a pedigree of competing in D1 GP. Speaking of D1 GP, Yellow Speed Racing\u2019s Dynamic Pro Drift coilovers were partially designed by triple Japanese drifting champion, Yoichi Imamura. A set of those will cost you $1900 (\u00a31553) normally, but at the time of writing they\u2019re on sale for just $1480 (\u00a31209).<\/p>\n

\"Modified<\/p>\n

The Best Stance Suspension for a Mazda RX-7 FC<\/h3>\n

To get the lowest possible stance without committing yourself to a life of scraping every driveway and speed bump, air suspension is the way to go. These kits rely on air compressors to lower and raise the car, meaning that you can slam it right to the ground at a car meet, before lifting it back up again for the drive home.<\/p>\n

The downside is that these things aren\u2019t cheap. The most expensive air suspension we could find for the Mazda RX-7 FC was the KS Racing Premium Wireless kit<\/a>. It comes packed with functionality including custom user pre-set ride heights, independent corner adjustment, \u2018rise on start\u2019, Bluetooth app control, and much more besides. The cost for all this tech? $6600 (\u00a35393).<\/p>\n

AirREX, meanwhile, will sell you a full kit for around $6000 (\u00a35000)<\/a> or you can pick up the struts alone without the management system for $2937 (\u00a32400). Airdynamiks offer one of the most attainable air kits for the FC though, priced at $2340 (\u00a31912)<\/a> for the full suspension and management system, or $1500-$2000 for the struts alone, depending on spec.<\/p>\n

For a cheaper alternative to air suspension, Yellow Speed sell a \u2018Super Low\u2019 coilover kit<\/a> for $1325 (\u00a31078). This will achieve an 80mm-130mm drop in ride height, but remember you can\u2019t just flick a switch and raise your FC back up again for the journey home.<\/p>\n

The Best Budget Options for a Mazda RX-7 FC<\/h3>\n

If times are a little tough and you don\u2019t have masses of cash to splash on some new suspension, don\u2019t worry too much. There are a number of options out there designed to cater to tighter budgets.<\/p>\n

On the coilover end of the spectrum, you could opt for a set of FIVE8s<\/a> for $705 (\u00a3574). However, be aware that these don\u2019t come with any damping adjustability, and instead will be pre-set by the manufacturer. But hey, at least you know that the spring rate will definitely be correctly set-up for the damper (unlike with simple lowering springs).<\/p>\n

If you don\u2019t see the point in non-adjustable coilovers, fair enough. Lowering springs with set ride heights can also be sourced for the Mazda RX-7 FC that simply fit around the standard shocks. They\u2019re much cheaper than coilovers. For example, well-respected Japanese brand TEIN offer FC lowering springs<\/a> for just $192. Expect a ride height reduction of between 1-2 inches with those.<\/p>\n

Peripheral Suspension Parts<\/h3>\n

Beyond the actual springs and dampers, there\u2019s plenty other elements of the FC\u2019s suspension that you can alter and upgrade.<\/p>\n

If you\u2019re after upgraded anti-roll bars to improve body stability through corners, Ultra Racing<\/a> will provide them as well as a range of strut braces.<\/p>\n

It may also be worth replacing any old worn rubber bushings with new polyurethane ones. In fact, speaking of bushings, JJLR Performance<\/a> sell a DTSS delete kit for $175 (\u00a3142).<\/p>\n

Best Suspension for Mazda RX-7 (FD)<\/h2>\n

What\u2019s it like as Standard?<\/h3>\n

For many, the third gen \u2018FD\u2019 RX-7<\/a> was the peak of Mazda\u2019s RX family tree. In fact, some might argue that it\u2019s one of the best sports cars to ever come out of Japan, and a big part of that comes down to the way it handles.<\/p>\n

Whereas the FC it replaced was quite soft by design, the FD restored the RX-7\u2019s image as a true driver\u2019s car. It was lighter, more powerful, and dialed in to attack apexes rather than glide over them. Its ride is by no means rough, but certainly gives more feedback than the FC.<\/p>\n

From the factory, the FD RX-7 came equipped with independent double wishbone suspension at both the front and rear of its chassis.<\/p>\n

\"A<\/p>\n

The Best Street Suspension for a Mazda RX-7 FD<\/h3>\n

For street use, the golden standard is Ohlins\u2019 Road & Track coilover kit<\/a>. Priced at around $2000 (\u00a31800), Ohlins R&T ensures that ride quality isn\u2019t sacrificed in the name of performance gains on the road. In its standard guise it\u2019ll be a marked improvement over the stock set-up, however if you really want something a bit more hardcore, this Ohlins kit can do that too. Making adjustments to the damper stiffness is quick and easy. For a more extreme performance-focused tune, all you have to do is turn the golden knob clockwise to put the coilovers into \u2018race mode\u2019. Then when you\u2019ve had your fun and your back\u2019s starting to ache, simply twist it back again for a comfortable drive home.<\/p>\n

Alternatively, BC Racing provide an ER Series set of coilovers for the FD RX-7, which they market as their most advanced suspension technology yet. That kit will cost you around $2000 including VAT, but if you can\u2019t afford those then BC Racing\u2019s BR Series<\/a> coilovers (as mentioned above in the FC segment) are also available for the FD.<\/p>\n

The Best JDM Coilovers<\/h3>\n

HKS is a tuning brand that most Japanese car enthusiasts will be very familiar with, and naturally they supply a range of coilovers for the FD RX-7. The Hipermax S kit<\/a> retails for $1750 (\u00a31427), though if you\u2019ve got a bit more cash to play with, the more advanced Hipermax R coilovers<\/a> are worth a look. Those are priced at a more aspirational price point of $2680 (\u00a32185) though.<\/p>\n

Sticking with reputable Japanese brands, TEIN Mono Sport coilovers offer 16-way damper adjustability from a single-tube design. A full set of those costs around $1500 (\u00a31300)<\/a>. Or, for a more comfort-focused ride (while still offering noticeable handling and ride height changes), you could grab some TEIN Flex Z twin-tube coilovers<\/a> for just $986 (\u00a3804).<\/p>\n

Finally, APEXi is a brand that\u2019s well associated with the FD RX-7. In fact, when Yoichi Imamura won the 2003 D1 GP championship in an RX-7, he did so as part of the APEXi drift team. A set of APEXi N1 EXV coilovers represent a fairly attainable option, priced at $1044 (\u00a3851)<\/a>.<\/p>\n

The Best Circuit Suspension for a Mazda RX-7 FD<\/h3>\n

Full-on track day and time attack builds require something a little more special though. Suspension which doesn\u2019t give a damn about roadgoing ride quality, but instead focuses on extracting the best handling out of a car on a smooth closed circuit.<\/p>\n

Nitron have pedigree in the grassroots motorsport scene, and with that pedigree comes both impressive tech and slightly daunting price tags. Their NTR R1 kit<\/a> is a proven beast for the track, but it will cost you $3432 (\u00a32798).<\/p>\n

For about a grand less, BC Racing offer their ZR Series coilovers<\/a> with 3-way adjustability, while KSport produce even cheaper options. Providing specialized kits for road rallies, drag racing, and drifting, you can pick up a set of KSports for $1615 (\u00a31317) over at Redline360.com<\/a> at the moment.<\/p>\n

The Best Stance Suspension for a Mazda RX-7 FD<\/h3>\n

For a seriously low stance that won\u2019t cripple your FD RX-7s usability, you\u2019ll want a set of bags. AirREX sell a full air suspension kit<\/a> (complete with digital management system) for north of $5000.<\/p>\n

Or, for slightly less money, you could bag yourself a Stealth suspension package with Air Lift 3P management system. That combination is available for $4631 (\u00a33748)<\/a>.<\/p>\n

Of course, there are much cheaper ways to get a slammed look, and we\u2019ll be covering those next\u2026<\/p>\n

The Best Budget Options for a Mazda RX-7 FD<\/h3>\n

As far as coilovers go, you don\u2019t really want to be cheaping out on those. As a general rule, anything less than about $600 probably isn\u2019t worth putting on your car, if you can even find kits at that price point for the FD RX-7.<\/p>\n

However, that\u2019s not to say that you have to spend four figures to get yourself a decent coilover kit. TEIN\u2019s Street Advance Z set-up, for example, provides improved handling and a lower stance for $765 (\u00a3624)<\/a>.<\/p>\n

Then we get to lowering springs. Whereas coilovers come with the springs and shocks combined in one package, lowering springs are just the springs, and thus have to sit around your car\u2019s stock shocks. This raises a few downsides as we mentioned above when covering them for the FC RX-7, however if you\u2019re really on a tight budget, you won\u2019t get more bang for your buck with any other option.<\/p>\n

H&R promises a 1-1.25 inch drop in ride height from its FD RX-7 lowering springs, which are priced at a comparative bargain ($258\/\u00a3210)<\/a>. TEIN S-Tech springs should offer a similar lowering effect for even less ($204\/\u00a3166)<\/a>. Or, if you\u2019re concerned about the impact that non-adjustable lowering springs will have on your FD\u2019s ride quality, you can opt for some TEIN High Techs. These only lower that car by 0.7-0.8 inches, and sell for the same price.<\/p>\n

Peripheral Suspension Parts<\/h3>\n

In addition to simple springs and shocks, you\u2019ll get the best handling results by upgrading other elements of your FD RX-7\u2019s suspension too. Hardrace suspension arms<\/a>, for example, allow for a wide range of camber, castor and toe adjustment. Plus, they come with rose jointed ends, removing any slop found in the standard ends which are rubber bushes.<\/p>\n

That solution may be a bit overkill if you\u2019re just doing fast road stuff though. If you\u2019re not doing serious time attacks, you\u2019d get favorable enough results simply by swapping the worn bushes out for polyurethane ones. Powerflex<\/a> does full front and rear kits.<\/p>\n

Geometry<\/h2>\n

Finally, it goes without saying that whichever generation of RX-7 you have, and whatever type of build you\u2019re striving for, you should always get a geometry alignment carried out after installing new suspension parts or wheels & tires. Your average garage should be able to ensure that everything\u2019s straight, but if you want to dial in some custom camber or toe set-ups, then head to your nearest specialist instead.<\/p>\n

How to buy the best suspension for your RX-7<\/h2>\n

If you\u2019re looking to upgrade your suspension, you first want to ask why. Do you just want the car to sit lower to the ground? Do you want height adjustability? Are you modifying a car for shows or for use on track? Which then leads on to questions about how often the car is driven on track, or how often it\u2019s used on the road. Each scenario opens up a different avenue of suspension tuning. If you\u2019re someone that\u2019s after lower looks and aren\u2019t bothered about improved handling, opting for a simple set of lowering springs will be all you need. For those looking for more performance but still predominantly drive on the road, you can look at both spring and damper upgrades, which could be a complete coilover kit.<\/p>\n

Coilovers give you the ability to adjust the height, and in some cases, adjust high and low-speed compression rates as well as high and low-speed rebound and more. The more expensive the coilover kit, usually the more features it has. For most, the need for 3-way or even 4-way adjustable coilovers isn\u2019t necessary, not unless you\u2019re chasing lap times or even 1\/4 mile runs.<\/p>\n

Coilovers will offer more performance than a simple lowering spring, but with it can compromise comfort. The higher end products will be tailored towards track-day\/motorsport applications. Air suspension on the other hand is a great option for those wanting more extreme lows without compromising usability on the road. With the ability to change the ride height at the flick of a switch, or tap of an app, it means you get the best of both worlds. What\u2019s more, the latest air suspension kits from the likes of Air Lift Performance are more than capable of dealing with the odd track day here and there.<\/p>\n

Why upgrade car suspension?<\/h2>\n

There are a number of reasons why someone may want to upgrade their car suspension. We mentioned a few above, such as if you intend to go on track in your car, or you simply just want to lower the ride height. But, someone may also be looking to upgrade simply to bring the car\u2019s ride to modern standards. If you\u2019re driving an older car (20 years+) it\u2019s likely sitting on very tired suspension if its previous owners haven’t replace it over the years. Opting for an aftermarket option can not only be sometimes cheaper than OEM options (if they\u2019re still available\u2026) but they offer a far superior ride quality and handling.<\/p>\n

While we haven\u2019t focused on any lift kits above, those who like to take their vehicles off-road may want to lift the ride height completely, for more ground clearance. You won\u2019t be able to do this with OEM suspension, you\u2019ll have to visit the aftermarket.<\/p>\n

Just make sure that the suspension you\u2019re looking at buying directly fits onto your car.<\/p>\n
