Spring rates and lengths

[yellowrad]

What is the concensus for SR4 (high down force) spring rates. I know this is not an exact science, but I just want to make sure I'm in the range.

My car is running 300 front, 350 rear.
And they are 8 inch springs, which seems inconsistent with what Radical seem to sell for the SR4. I think they seem to spec 6 inch springs in the sr4 manual.

What is everybody running on their SR4 or PRO6 I guess,

Cheers,

Jon

Shorter springs = less weight

So long as you have enough thread on your shocks to run shorter springs you can only really benefit from fitting shorter ones.

I'd start with the factory spring rates, they spent a lot of time testing to get those rates
