In the present day, the Mazda RX-8 is undoubtedly one of the most impressive bargains on the market and could potentially end up being one of the biggest bargains you’ll ever be fortunate enough to buy.

With proper rear-wheel drive, high-revving manual gearbox JDM sports cars becoming more expensive than ever, many enthusiasts are scared of the maintenance requirements of a rotary and the gas bills that come with it.

However, what if those don’t bother you? Perhaps you want a cheap, yet stylish daily, an affordable drift car, or you maybe even want to strip it down to build a bargain project car? The RX-8 really does tick so many boxes.

Thinking of engine swapping a cheap RX-8 with a blown engine? You will definitely want to invest in a set of coilovers to help manage a heavier (V8?) lump.

We stated in our RX-8 exhaust guide that it comes down to looks, sound, and price when it comes to choosing the perfect option.

However, coilovers are a little more complicated.

We highly recommend setting aside a decent budget, unless you’re planning on slamming it on its ass without too much concern with handling or durability.

However, if you’re doing anything else, you’re going to want to go with something that ticks as many of the right boxes for you as possible.

We’ve covered everything in our guide, from those who want to throw the car down sideways, scrape their way along the ground to the local meet, have a perfected canyon carver which can still do the school run or shave valuable milliseconds off on your time attack monster.

In this guide, we’re going to cover the cheapest coilovers on the market to one of the most expensive and pretty much everything else in-between.

Despite being capable of some serious lows, these aren’t a crashy, uncomfortable ride like you may suspect. These are a great all-round coilover for everyday use.

We highly recommend considering the swift spring optional upgrade to make the most of this kit.

These are great if you’re looking for a simple street coilover with plenty of adjustabilities. With the swift spring option, these are a fantastic potential choice for the price.

If you’re looking for a more track-orientated coilover, their high-end BR Racing ER coilovers with external reservoirs are worth checking out.

  • Purchase link: Buy your TEIN Flex Z coilovers here

Our comment: JDM tuning legends TEIN have certainly stood the test of time, and are one of the well-known suspension companies in the tuning scene.

The Flex Z is their latest in a range of extremely competitively priced setups and despite the price, they’re still made in Yokohama, Japan with their typically exceptional eye for quality. The difference with these is that they have reduced their costs by making the body a sealed structure. This may initially sound like a bad idea, but at the price, it’s often more expensive to get a coilover system rebuilt than buy an entirely new one!

Despite being road orientated, these are also an extremely capable track coilover. These are also compatible with TEIN’s EDFC electronic damping system, which allows you to control the damping from inside the car at the touch of a button. You’re going to struggle to find a better setup for your money than what these have to offer.

Manufacturer description:TEIN Flex Z Coilovers are the latest in TEIN’s generation of high end coilovers. The difference with Flex Z is that you are getting a coilover that would normally cost almost double the price.

The new manufacturing systems that TEIN has put in place with this line of coilovers has allowed for them to produce these coilovers at a lower price and pass that savings on to you. Quality and performance remains top of it’s class and TEIN builds these Flex Z coilovers with the highest quality standards in Yokohama, Japan making these a true Japanese JDM coilover system.

Our comment: You’d be forgiven for wondering why we’re specifically reviewing two sets of the same brand, but we just couldn’t help but notice the insanely cheap price of TEIN’s entry-level kit.

These are of course a basic setup and don’t feature dampening adjustment, but you can still count on TEIN’s typical JDM quality to shine through in all of their products.

We’ve found many happy owners that just wanted to do basic tweaks to their ride-height who are delighted with this setup. For less than $600, it really is a steal.

Our comment: KSport have gone out of their way to bring the only drift-orientated coilover setup to the RX-8, so it’d be rude not to feature them!

For those of you that are planning on kicking the back end out on your RX-8, these could well be a fantastic choice. You may require some additional suspension mods to get the most out of the car, but these will undoubtedly be a good start.

If you’re not looking for a drift-orientated coilover, but you’re keen to go down the KSport route, then make sure you check out their Kontrol Pro alternative too.

They’re still not very commonly found in the RX-8 scene, but we’ve heard good things. They’re definitely worth considering if you’re on a budget. If you’re using the car for the track frequently, we’d advise spending a bit more money on a superior kit to maximize the true potential.

Our comment: Now that you’ve (hopefully) recovered from looking at Moton’s suspension porn and then your disappointment when you saw the price, we present one of the kings of suspension – Moton.

Now, these obviously aren’t your average daily driver setup, however, they are up there with the top elite when it comes to perfected track setups. If you’re serious about setting the best lap times, you are undoubtedly going to love this incredible option.

Manufacturer description:The 3-Way adjustable Moton damper features 15 positions of high speed bump, 6 positions low speed bump and 15 positions of rebound adjustment. The low speed bump adjuster is located on top of the high speed bump adjuster and can be adjusted in dependably.

The 3-Way adjustable Moton damper is using, like the double adjustable damper, a unique blow off valve system in the canister to totally control curb stones and bumpy track conditions.


Our winner

Our winner is the highly acclaimed KW Variant 3 (V3) coilovers.

Of course, the Moton’s are unquestionably the better setup, but they’re purely track-orientated and way over budget for most owners. With the V3’s, they offer a great all-around package which will ensure the best performance both on the road and the track.

Runner-up

It’s been an extremely close call to decide a runner-up in this guide, as you’ve probably noticed from so many 4* ratings, but we’re going to have to hand this one to the TEIN Flex Z. With fantastic value and their renowned Japanese quality, they’re a great choice for those of you on a budget.

Combine these coilovers with their unique EDFC system and you’ll be prepared for whatever comes your way on the street or the track.
