18 kg savings in unsprung weight is a lot man what were your old wheels three piece dino-licious tractor rims held together with 150 bolts dipped in extra chrome and super rice dish with agressive offset? Do you feel and like the difference in performance?
My first time at winton is 2:03.5481 (semi skim; started weight reduction ideas but not fully developed yet, eg seats, toe hooks, glove box etc still in the car, just the HU and speakers, are out)
Seccond time at winton best time is 1:58.6100 (skinny; wheel nuts have been shaved down to take one size smaller socket, no pasenger seat 1/2 tank petrol, coilovers have been installed, car has been corner weighted and aligned to spec, stainless lines installed). Coilovers are 1.5 kg lighter than stock shocks I consider it technicaly as unsprung weight savings
Same conditions (35 deg day) same driver (65kg) less weight = 5 seccond difference!
Third time going to winton is this melbourne cup day, I have something planned...
