Suggestions needed: Spring rates/no swaybars for 318is

[BrandC]

I'm doing a bit of probing before I buy the Ground Control/Koni coilover kit. I do NOT want to run aftermarket swaybars, I want to control bodyroll with high spring rates. This setup is meant for track-duty, but it will see street time too.

What rates do you guys suggest? I've seen 600f/650r for a track setup and the owner really liked it at his first track day (I forget your SN, I'm new on here!). TIA, cheers!

600/650 is just begging for understeer. There are many schools of thought on this, but from what I've seen and exerienced, you want about a 2:3 ratio for spring rates (at stock mounting points).

I recently got 440/700# GCs. I know a lot of ppl run 475/650 and are quite happy, but I wanted a little more rear bias.

For a car that will see the street, I really dont think you want to go higher than 475 in the front and whatever you feel matches it well in the rear.
