[flaccidracing]

I am 270lbs. I want to do the gt thunder link and revalve/respring my rear shock. What sould the spring rate be. Gt shows it in lbs and eibach shows it in 3.2,3.5,3.5etc. How do I know what eibach spring to buy.

im not sure on the spring rate, but im about 245 pounds and i had my local elka supplier send me the stiffest spring he had, and he said it was the stiffest elka stock and its been great.

being that heavy, you need to start at the stiffest. ive had lots of problems with spring rates example in the fronts i run 5.4kg main springs which are pretty heavy.

id try and get the heaviest you can and start there.
