unfortunately, my friend found out the hard way that stiffer springs can go both ways.. too soft affects braking by putting too much load on the front tires and letting only 2 wheels do the job of slowing the vehicle.. but too stiff affects it as well. my friend bought some 650 lb. springs in the front for his m3.. that plus the -3.6 front camber has increased his braking zone.. enough weight needs to transfer to the front to push the tires down and increase contact.. it's finding the correct balance that's difficult..

rebound is also important to auto-x.. i learned a great deal tuning my friend's m3 since the koni yellows are rebound adjustment only.. having played around with it, it's been helping me tune the s2k's rebound more efficiently.. quicker rebounds in the rear allow the quick weight transitions allowing the tires to grip soon.. i found that generally stiffer rebound settings in the front, and quicker rebounds for the rear work well for rwd.. while vice versa for fwd..

anyone want to comment on rebound settings or make any corrections? i haven't talked to as many people about playing with rebound.. so far most of my knowledge has come from experimenting with trial and error..
