Searched the threads on spring rates & didn't find what I was looking for (or threads weren't really answered). I currently have 500F/350R in/lb on my "DG" coilover setup. I finally made it out to a lapping event last year & I'm looking to do it more often now. I know I need more spring rate in the front, but curious what people with more lapping experience think.
Car is basically full weight, has ES bushing throughout (might swap to Prothane), currently stock sway bars but will be getting RM bars. Tires will just be "max performance" street tires (ie currently Kumho XS, probably try RS3's next, etc), in 235/40/18 size. Shock's are stock valved Koni yellows & I currently do drive the car daily in the summer as well. Currently run stock rear LSD, 4 spider center & stock front diff with TRE rip grip. I will be installing an evoVIII mechanical rear diff (with plates re-stacked in the correct order).
I know at one time people thought the limits for stock valved Koni's were ~600 mark, but seems they have since run much higher rate springs, without issues. My origional plan was swapping to 600lb/in in the front but talking with someone with more experience then me, he's recommending I go right to 700.
