Budget NC coilovers, revalved Bilsteins

grippy · Post by **grippy** » Mon Jun 15, 2009 9:26 am

I have a set of low mileage factory Bilsteins (9K) from 2006 Miata that I had revalved for stiffer springs for track use. Set up for 750F/450R spring rates. The shocks now have a treaded cap on top so changes can be made easily (stock has a crimped on top that is not servicable). includes coilover threaded sleeves purchased from Mazda motorsports ($280). Also included Goodwinn spring adapter to run 2.5 dia springs if desired ($80) Springs may be avialable seperately. $750 or BO

My wife found a job so I got a set of Ohlins which is what I wanted in the first place. I also ran Ohlins on my old car (ITA 95 Miata).

These Bilsteins are very similar to a Spec miata setup.

since i'm thinking that 750 lb springs will be not so fun as a daily driver, what do you think the softest spring rate i could run?

Higher spring rates are not too bad if the shocks are valved correctly. These have just a bit more compression damping but a lot more rebound. I think they could handle whatever you want to put on them. I had them set up that way on a dedicated track car, it was firm but not too bad. I'm sure you could go lighter on the rates and be fine. If you decided that you wanted something specific they could be easily changed now that the caps are machined. The stiffer rates do a good job of fixing the body roll under cornering.

you should let me try them out before i buy them.

i've had pretty stiff coilovers on my old Civic Si but i'm not sure that i'd be ideal for a DD.
who can do the revalving if i felt it was too stiff?

This is where I had the work done, Bernie is a good guy. http://www.stewartdevelopment.com/
Anyone who does Bilstein rebuilds can do it. Shaikh at Fat Cat also does a nice job. He could even make them rebound adjustable if you wanted. But there is probably someone closer to you that can do it.

OK, I will include a set of 750 x 8" front and 450 x 8" rear springs, all ready to go.
