My friend (A-group TD) is going racing this year, after one yr of TD's. Good rider, smart/safe/smooth/semi-fast A-group....well thought out, not banzai rider. He still intimidated about going from no-throttle to on throttle mid corner. He gets good lean angle for TD tires. Gsxr750. He weigh about 175 w/out gear. Just bought used bike to race. MW slow/med speed tracks (gateway/mcra, BHF/CCS, etc). He rode bike once and doesnt like the lack of power and weak midrange (prefers his 750 motor). Bike is oem 2008 gsxr600, oem stock except for, SS-lines, pipe, case-gaurds, Brembo lever and race-glass. He doesnt have money for aftermarket suspension/geometry right now. I reccomended him a 520 converesion w/ -1/+2, to give the bike some ass. And Kurvygirl vesrah std RJL's, for braking power/feel. And Pirelli or Mich race tires + warmers (I loan/give him my old warmers) Any other low-cost suggestions? I think my 01 oem 600 had 10-mm spacer on rear oem shock and flush Forks/Triples. Would that hold true for an 08/600? Thank you!!!
