I assume you have a monocoque with inboard suspension? In which case around 120lb is recommended.

You are correct, that's the setup. Thanks for the advice.

Just purchased a part complete project and would like to know a starting point for the spring rate from what's already there. These are Spax M73's. The car had a cross flow and we're just installing a ST170. I'm going to change the springs and dampers and like to establish my starting point.

Any suggestions would be appreciated.
