Hey guys had a couple of questions. For the mk1 rabbit rally car we are going with some HDs but want to revalve them to use either mk2 springs or b3 springs. I've heard the b3 springs are great but not sure if thats b3 rear springs as well. Also how do I find the compression to send to Bilstein when its time to revalve. Thanks a bunch. Input and opinions always welcomed.
Tell them the type of use the car will see (auto-x, hill climb, street, etc) corner weights, spring rates, and whatever else is pertinent and let them guide you on the revalve. When I was buying my shocks they were helpful and my car handles pretty damn fantastic now.
