So, bought a lexus is200 sport and now it's time to prepare her for the Nurburgring end of September 2011, so far cambelt change, service, pipercross induction kit, a few cosmetic bits and bobs, but I'm going to concentrate on the suspension mainly, and maybe some wider tyres, would love a supercharger, but I think suspension is important, question; what suspension parts should I replace? Was thinking; coilovers, antiroll bars, new polibushes, strut brace front and back?
