Why Settle for Less? Tech Tip 31: When we run suspension strategies for lower chassis/body roll, the right way is to run a larger sway bar in the front & stiffer springs in the rear. If we were to run stiffer springs in the front, we would reduce our precious front end travel that is key to the lower CG, better downforce & other performance benefits from a high travel suspension strategy.If we were to run a stiffer sway bar in the rear, instead of stiffer springs, we would simply be picking the inside rear tire off the ground when cornering. This happens if the rear sway bar rate gets close to the spring rate. So larger bar in the front & stiffer springs in the rear it is.With stiff rear spring rates, the spring can come out of its cup in some circumstances. That would cause the spring to ride on the coil-over shock threads & eat them up. Bad. Solution?Take-Up Springs & Dividers on the Rear Shocks. So, we include them in RSRT packages that will use stiffer rear springs.182'
