What spring rates???

[aerosam]

Hi guys,

I'm almost ready to go ahead and buy my suspension, I've been putting it off for ages as it costs so much.

I know what length dampers I need, but I haven't a clue when it comes to what poundage springs would be appropriate.

The engine is a little heavier than normal, at 146kgs and at the rear I'm using semi trailing arms with an anti-roll bar, if this make any difference at all.

Oh, and the car is going to be used on track only, so handling takes a major precedence over ride quality, as most tracks will be fairly smooth anyway.
