The other complication is that many 'progressive' springs are effectively linear when installed, and are only progressive to keep the spring captive at full droop - I know my front low Kings are this way. This may well not be the case with your stock rear springs at all, but just a thought.
I find it hard to believe that the original stock springs would be progressive anyway.

Joel,
It is really a question of how you like a car setup as well.
I know from the days when Jim Ricghards and Mark Skaife were together, MS liked the back end of his car setup so that it was soft in the rear which would give very good power down pout of the corner, but would easily pick up the inside front wheel.
My RX2 was setup like this, and it had 400lb/in fronts (a little hard) and 200lb/in rears and was used for cct work only.
Get your current ones measured and give the harder ones a go and see what feels better as well as compare lap times.
Don't forget that if you change the spring rates and keep the same heights, your dynamic roll centres will change as well.
Cheers
Michael B

Hmm good point there Michael.. It might not necessarily be an improvement firming up the rear end. Or more should say it might not equate to quicker lap times.
