Don't do it. Save your 6 dollars and buy a sandwich. You'll get a better return on your investment!

There is a guy on the MSM site that bought some. Not much feedback from him because everyone gave him **** for buying them. I'm sure if they didn't work out he wouldn't say anything. My opinion, I would not put them on anything I drive.

lemme guess - the apex is on the asphalt not the curbing/strips?

well it depends...I like to put the outside tires on the inside paint in turn-1 at hallett.

I think the curbing on the track is much easier than pot-holes.

rum rum rum rum = easy
thud = drama

Well I dunno I think I might do It just to try and save ~350 dollars?

I was just about to try it. Cheapest road to corner weighting, and you can always put in your own springs. People are always selling springs, and they never* go bad. My car has 4 different heights on 4 different corners, and have always wanted to be able to adjust this (and maybe lower a little) without paying out the nose for coilovers.

The only real problem (out of the box) is the incredibly high and unbalanced spring rate. To use them you'd have to spend the money saved to buy decent adjustable shocks to match those spring rates. Add to that a stiffer front sway and tower brace to be able to manage the oversteer induced by stiffass rear rate (oversteer...something every turbo miata needs more off). As said before, if you buy real springs the cheapo collars are probably worth it.

You have to have a shock that can handle the rates, the blue ones are 450/350. I run them on my MSM with the stock Silver Bilsteins and they are great. Ran in TT,HPDE4, and HPDE2 this weekend by 3 drivers at a NASA event, my car was hored out. They have about 1500 street miles and 500 track and are still great. Varified by Hustler at NASA this weekend!

I'm using the sleeves on Konis with HR springs.

I've had them for a few years and ~30k miles with KYB AGX shocks. The ride is stiffer and the handling is better than stock.

Garbage. Bouncy ride, no R&D, unknown rates, the threads rust, and so much more.

You get what you pay for.

I would use the coils and sleeves if I could, on the FM springs that I have now to do some fine tweaking but the springs you get with them are throwaway items.
