All the handling benefits of our Stage 2 suspension with some extra travel in the rear for an even better ride.

We consider this suspension package to be well designed for the Miata that has to do everything. For example, when we go to a track day, we have to drive 5 hours over twisty, bumpy mountain passes to get to the track. Then, after pounding our turbo Miatas around the track all day, we drive home over those passes. This suspension is equally happy in both situations.

How much will this kit lower your car? We can't tell you, because Mazda changed the ride height of Miatas over the years. However, if you measure from the center of the wheel to the fender lip, you can compare your car to the final result. It's not a huge drop but once you drive the car you'll appreciate how well it works.

A new rear spring design allows the popular FM rear mounts to work with Koni shocks. Previously, this was a combination that was not recommended.

A common question is how this setup compares to retrofitting an NB setup to an early car. Well, that's easy: it's better. The FM mounts add a significant amount of extra travel in the rear.

Specifications:
Front springs: 318 lb/in
Rear springs: 233 lb/in
Front ride height: 12.5"
Rear ride height: 13"

Includes four springs and shocks as well as two rear upper shock mounts and new polyurethane bumpstops all around. We recommend you check the condition of your front mounts to see if they have collapsed. This can be done while they're installed.

Great solution

I have driven with this setup for about 10 years now and I love the setup. Definitely firms up the suspension and I added beefier sway bar attachments in the front. I have had no issues.
Car corners flatter, steering is much sharper, and car no longer feels "floaty" when going above 75 on the highways.
Ride quality is not harsh, but roads can be and this suspension kit definitely points out all the surface imperfections to a larger degree than stock. Stock setup, while really good, ultimately is more tuned towards comfort and is softer. Obviously.

Total Control

Love the control this suspension provides both on the track and as a weekend driver. We spent two days on the Tail of the Dragon and the NA held up well and kept up with the 9 ND's through the corners too. Having the ability to stiffen the suspension when we needed it on the Dragon and then soften it for the 10 hour drive up and back from Tampa was perfect. Only regret was not buying them sooner.

Not for track use

I bought this for my 97 intended to be a track car. After around 10 track days at VIR, the circlips holding the spring perches to the shock popped out and the perch dropped to the A arm. I replaced them with safety wired retention rings, and it happened again. This is an inherently weak design, not up to track use.

Note from FM: A failure like that would only happen if there was coil bind. The Koni perch mounting is a design that's been proven on street and race Miatas for 30 years. RBR, please contact us.

Plug and play upgrade for my NA6 suspension

Bought an NA6 Miata that was tail happy in low speed turns. Was looking for a more planted rear. It’s been two weeks since the install, and the Stage 2.5 FM Koni kit works great. (To be sure, I got new tires and an alignment, too; they are probably contributing to my satisfaction). But, for street driving, I’m very pleased with the FM Stage 2.5 kit. The low-speed fishtailing problem is 100% gone. Car is planted in the corners, and rides very comfortably otherwise, with no reduction in the playfulness and chuckability of a superb factory chassis. Too, the shop had to make no mods while installing the kit. (Set-up note: My front sways are on the soft (outer) setting. My rear sways are on the middle setting. The Konis are set at fully soft for the rebound, and at the highest perch height.)

Go for it - highly recommended

Works great on the street as a daily commuter and really makes a huge difference compared to stock suspension. Significantly "tighter" feel without being harsh. Just low enough but not too low. Hard balance to achieve, but FM kit just works! With this kit, I had no need for a spring compressor, I assembled all before mounting in my 96 NA. With FM suggested settings for ride height on the Koni perches, I ended up with 12.8" front and 13.0" rear (fender lip to mid wheel). I wasn't convinced that the dual pitch spring (fronts only, rears are single pitch) would work well but they do. Trust FM on this one. Sway bars also made a big difference in body roll. Car feels tighter and more in control. Installation is easy but takes a while because of all the miscellaneous suspension bolts that have to be loosened or removed. Marking the location of alignment bolts before loosening allowed me to put the suspension back together and have acceptable alignment for a couple of weeks to let suspension settle down before real alignment. FM should make a youtube video of how to assemble the shocks/springs/mounts as well as the disassembly/ assembly process to help out beginners. Documentation provided is sufficient but could be better with at least showing photos of main steps. Hardest part of this job was tightening the top suspension nut on the Konis since there is no flat to stop the shocks from spinning (Koni design related, nothing to do with FM). Overall, after 1000 miles, the FM Koni stage 2.5 is definitely worth it. Well put together kit that takes the guesswork out of picking individual parts that work together. FM's experience in Miatas shows again.
