190E custom spring dimensions

[kiato4]

Hi all:

I have tried a bunch of springs on my 16v and none have made me happy. I tried H&R, cut 400E, cut SL500, and Vogtland. I want to get a custom set I can play around with. Hypercoil has 3" ID springs that I have read will work on the front of the 16v, and 2.5" ID for the rear. What spring rates would be a good starting point and what free length? I want something like the H&R with a stiffer rear.

If anyone can measure the free length (ie uninstalled) of some 16v and sportline springs, it would be greatly appreciated.

Thanks.
