Does Eibach make custom rate progressive springs?

 

just really expensive, german made, "tender" springs for use on top of their normal springs. but you need to get shorter main springs in order to fit them in the shock with the 3" tender spring.

wasnt there some suspension company, something like "KMF" or "KMS" that showed up at RR/AX touting their shocks with progressively wound springs saying its BETTER than all the rest, and got totally laughed out.....

why you looking for progessive springs? want to adjust height with a more comfy ride in rear?

have you considered a "hybrid" setup with a regular aftermarket spring like H&R in the rear, and your custom GC rate in the front. then cut the dead coils in the rear to get to the height you want. i dont think you want progressive spring rates in the front if it was even possible. the engine weight will just go through the lower spring rate once the car is squatting. stock front spring rates are not progressive, only the rear.

or just get koni neuspeeds with 5 height adjustments and your choice of spring kit. im sure thats plenty to find a decent ride height you want.

 

The plan was to use progressive springs in the rear for a better compromise in ride quality. I think I'm just going to use the Prokit's I have in the garage for now. I want to improve my driving before moving on. Thanks for your input.

 

meh, i think youll be fine on the street with OTS rate GC. particularly if you have adjustable shocks like illuminas. i was good with GC and illuminas on a CRX.

actually i did the hybrid spring setup with my pro kits and GC. used the front pro kit spring up front, then used a 450 spring in the rear and matched it to the pro kit ride height. worked fine. just adjust the shock to a more comfortable level for the street.

the good thing about illuminas is that it adjusts both compression and damping simultaneously, so *i think* its better suited for adjusting to different spring rates and ride levels.
