I've just got back from the Ring...
First time in my Golf, not set up for the Ring at all really, only KW V1's, Porsche brakes on the front but crappy pads and old P Zero Pirelli's, the rest of the bushes, drive line is standard. Car is stage 1 ish, 320bhp.
I managed a 8:38 on my 4th lap which I don't think is too shabby, I'm going to do more mods (Roll bars, bushes, tyres etc) and go back to hopefully get faster, with handling mods I think an 8:20 ish is easily possible!
