Ron here from Texas....
I would like to seek your help about spring rates.
Background:
Currently I have a coil over kit on my 83 A1 VW GTI.
The car is used in SCCA ITB.
Front springs are 375lb/in and the rear are 325lb/in.
Car handles very well, fairly neutral, with a little oversteer if I lift or trail brake in a corner.
This was fine for the first 1 ½ years in the car. But the car does have some roll. Now I feel like I would like to increase the spring rates.
Being the cheap guy I am, ....I was thinking of taking my front 375lb/in springs and moving them to the rear. Then purchase a new pair for the front. So, I need to figure what rate to try next in the front.
I did a little math....325/375=a ratio of 0.866666, so I assume I would need to keep the ratio number close to the ratio I have now, since I like the way the car handles.
Plug in a new front spring rate of say 450lb/in.....and I get 375/450= a ratio of 0.833333
or maybe a new front spring rate of 425lb/in.....375/425= a ratio of 0.88235
Both are close, What does the group think? 450lb/in or 425lb/in?
Am I even doing this right?
