#3 Road tyres as can't be faffed with slicks currently have 2 sets of wheels. staggered 13's. have 888Rs on one set and ZZS on the other. Looking for next option to replace the ZZS soon for obvious reasons. have lots of experience in M3 setup but new to the Caterham fraternity, so advice from any track day enthusiast welcomed. I just want a good track setup for any track legal road tyre. on ride height....if I go too low does it mess up the caster?? Is there an optimum height to try? standard 2016 springs and bilstein shocks. Spring rates unknown to me. thanks what do the the Caterham race series run? Anyone involved Willing to share. thanks in advance
