FM2 suspension (street/track car)
 

Just bought a J32 swapped Miata. Its this car here ---> https://bringatrailer.com/listing/19...mx-5-miata-20/

A few notes:
- Engine is awesome. Completely different power delivery than my old turbo or my M12. The sound is absolutely incredible at full tilt. I've got a welded up solution to the "catilevered" engine mount situation.
- The suspension is FM Tokico, Raceland adjustable perches, and FM anti-sway bars with adjustable end-links.
- I don't quite fit in the car comfortably given the Corbeau seats are bolted on adjustable rails and seats don't go all the way back (I am 6'3")

I drive the car on a combination of street/track but the car seems slightly under-sprung given the addition weight and power. Done a lot of reading on the forums for the inevitable "Just buy Xidas" but wondering whether there's a short term bridge to simply up the spring rates in the meantime. This will have the added benefit of keeping the car's total motion more limited (since the car is ultra-low for the skid plate). Will the Tokiko's be up to the task or woefully underdamped if I take the path to Xida spring rates?

Woefully underdamped and generally ancient and bad.

No point spending money on another crappy setup.

if you can afford the best get xidas.

or for $1k you can get bc racing coils. I'm running them with 12k/8k springs and they're comfy on the street and perform well at the track.

I don't want to buy bad parts twice.

I'll drive it on this setup for a while and squeeze every tenth than make the step to Xidas sounds like is the ideal solution.

Not sure if you dug up Lars' old posts on the matter, but if you're actually doing 50%+ time on the street I think the tokico illuminas (not the blues obviously) are actually a fine compromise for the cost (or in your case "free").

I love the tokico illuminas and FM springs for pure street use. They are marginal at best on track and will quickly wear out if that is where hard driving is done. I would be saving up for Xida's and just do the suspension once.

Wow. Great deal for $8K.

Anyways, like others said it's wayyyyyy too undersprung and underdamped. If I were you I would get some time on the current setup while saving up money, then grab a set of Gen2 Xidas or BCracing w/ custom spring rates. FEAL also makes a decent setup with custom spring rates.

So you are the guy who got that screaming deal. The previous owner is also the owner/operator of a very good Mazda shop. He does a lot of Miata repairs (including an engine rebuild I had him do a few years back).
