coilover spring rate

what would you recommend for coilover spring rating for a 90 CD 5 cylinder? i figured around 200 lbs, is that too stiff?

what are you guys running in your rally cars /shorties ????

300lb matched all round, 2.5" ID and 8" long.

Well on the front of the QC we have 10"X 260lbs springs and on the back 11" X 240lbs all with Koni adj shocks..

On the 80 we have 10" x 220lbs fronts and the backs are springs from an avant with a little bit of a trim again Koni adj shocks.

But we are just about to up the ones on the coupe to 300lbs and put the 260lbs on the 80.

Hi Styler, I've done a few sets of coilovers that are being used on group 4 tarmac cars, I used 500 and 450 with 300mm and 280mm length, ID 82mm, with billy inserts.

I use 500 front and 450 rear on 500 bhp ur Quattro with billy inserts,handles like a go kart but very firm

this is for road use, 300+ would be too hard would it?

s2rob · 23-05-13, 09:10 AM

I think 300 is good for the road,mine is a bit harsh at times
