I'm selling a fully-sorted budget race suspension from my miata. My co-driver and I were quicker than many corvettes, STi's, EVO's and other turbo miatas at Detroit auto-x events last year on this setup. We were on Kumho Ecsta 215 street tires and WITHOUT AN LSD!!

The only street miles on this setup is driving to and from the track, and a brief period of time (maybe <1000 miles) where I was daily driving it in summer. Probably did six events on the whole thing.

Components are as follows:

R-package Bilstein dampers (from California car with <75k miles) - These will last a long time without a rebuild. Work really well with the higher spring rates. No leaks, dings, or shaft damage.

Coilover sleeves and springs are from an ebay kit. The spring rates are NOT 450/350 as is the general opinion around the internet. I have measured the rates on a good spring tester, they are in fact 440/325 which changes the front/rear bias a fair bit.

Custom upper spring locators - These keep the spring centered under full rebound. This is not part of the original ebay kit. You will need NA or NB mounts to fit this to the car, however.

Flying miata 1" front swaybar (94-05) - I had the stock rear swaybar in because I had no LSD, and I like the setup a little loose. If you want more understeer, you need to disconnect the rear swaybar completely.

Heim-jointed drop links (endlinks) - These are not the cheap mcmaster rod ends. Each drop link is made of two chromoly steel rodends with a teflon-coated steel race, and has a jackscrew which allows adjustment without taking the ends off the car. As good or better than the FM end links.

Since I believe that the suspension works together as a system and not the sum of its parts, I'd like to sell this whole.
