The Miata is an incredibly fun car to drive, straight from the factory floor. That doesn’t mean it can’t be drastically improved by the aftermarket. Plus, THAT WHEEL GAP.
This guide will focus on the best “streetable track use” coilovers for the NA/NB Miata..
Are NA and NB Miata Coilovers the Same?
People finding a deal on NA or NB coilovers when they have the opposite generation causes this question to come up in the forums quite often. Luckily, it’s pretty easy to answer. No, NA and NB coilovers are not the same, BUT, you can use them between generations IF you use the complete assembly as a set. This means that your shock, spring, and tophat must all be the same generation to fit properly.
Most people use the NB style tophats, they were redesigned by Mazda for better suspension performance.
Here’s a great video by Flyin’ Miata:
NA/NB Miata Coilovers
Okay, here’s our list of favorites. Roughly in order of which we’d want most on our own ride.
These are the top Miata coilovers on the market, with “More road racing national championships around the world than any other Miata coilover.” They have custom spring rates depending on your tire setup and use.
The biggest takeaway I’ve had from riding in cars on Xida’s is that they ride incredibly well for being a pure race coilover.

Goodwin Racing Spec Feal Suspension 441 Road Race Coilovers
These are a newer entry to the market, a collaboration between Good-Win-Racing and Feal for the NA/NB Miata. These are only a slight price increase over the street/track Feal coilovers. Featuring spring rates that make sense on the track (12k/8k) and the valving to match.

5X Racing Bilstein Coilovers (Budget Bilstein Ballers)
These are probably the best budget alternative to Xidas, coming in at roughly half the price. They’re available in multiple spring rates and with either lower height front springs for race track use only or taller front springs for a more streetable road height.
Flyin’ Miata V-Maxx XXtreme
These coilovers take the classic V-Maxx and add adjustable damping. They come with 504 lb/in front spring rates and 336 lb/in spring rates in the rear.
These are available from Flyin’ Miata for $939 and will require NB top hats if used on the NA Miata.
MeisterR ClubRace coilovers
These are designed for high grip tires and occasional track day use. 12.5k/7k spring rates.
Available from Good-Win-Racing for $1345.
Budget / Ebay Coilovers for the Miata
These are all coilovers, that may or may not be made in the same factory. There is really little to compare between them. They all offer roughly the same build quality, or lack there of. They typically have poor valving that isn’t a great fit for the spring rates. It’s typically better to save money for later rather than spend on these.
K Sport Kontrol Pro Coilovers
These are a more budget friendly adjustable coilover, featuring 36 levels of damping adjustment. They also include Pillowball Top Mounts, for improved steering feel. These come with a more street friendly 8.7k and 6k spring rates.
Typically available online for ~$850.
Stance USA 90-05 Miata
These look to be budget / low quality coilover clones.
Available from Valex Racing for $1255.
TruHart Street Plus Coilovers
another cheap coilover clone.
Available from Coilover Depot for $578.
Megan Racing EZII Coilover
noticing a trend? It’s probably best to not buy coilovers in the ~$600 range.
Available for $699 at Coilover Depot.
These are probably direct from the same factory. This shows the true cost of these cheaper coilovers.
Available on Amazon for $219.99. (With top hats for $299)
Rev9 Hyper Street II Coilovers
Again, a budget coilover clone.
Available from Redline360 for $532.
Raceland ultimo Coilovers
An affordable street coilover with ~480lb/in spring rates front and rear.
Available for $469 from Raceland.
