I'm looking to upgrade my currant setup to try and control the body role I am getting. I currently have 26mm fsb on soft, 24mm rsb on hard, eibach multipro r1 coil overs with 300lbs front and 350 lbs rear springs. Alignment is -2.6 front and -1.7 rear. I'm finding that in sweepers I can't carry any speed through a corner. The car just rolls over and scrubs the outer edge of the tire off. I am thinking I need to go with higher spring rates front and rear. What spring rates have others been finding works well for our cars?
