Spring stiffness Phoenix

Hello,
I would like to buy new dampers for my Sylva Phoenix.
What spring stiffness do you think I need (mainly trackdays)?
At the moment there are old Spax fitted, what do you think about AVO, Protech?
Regards
sdenne

Hi there. When we were building our Stuart Taylor Phoenix we took advice from our friend and multiple Championship winner Tim Gray. I doubt that anyone knows more about the Phoenix than him. He said to use 250lb springs all round. This is on an independent rear end car. As regards the shocks we used R1 bike shocks but I can't recommend this course of action. Lots of extra work/adaptation, although they do work very well.

My advice would be to concern yourself with the Dampers as well as the springs.

How heavy is your car?

The internal set-up of the dampers should be suited to your cars weight. We all just go and buy some dampers, me included, and then wonder why the car shakes the teeth from our head! (mine does) The main reason is not spring rates but the internal damper settings.

I believe that ProComp will sell you a set of dampers with the damping ratio adjusted to suit your car - I'd talk to them. In fact replacing my AVO dampers is on my list of things to do and when I do it I'll be talking to ProComp
