You reach 180 at Calder about 3/4 of the way down the Straight. The guy in the white 34 with gold bbs wheels (sorry dunno your name) was driving down the straight sitting on limiter lol and as for hicas, that's long gone, I have a lockbar.
Good day! Managed a 1.13.06. Pretty happy with that. Definetly need more power down the straights, was good to keep up with a c63 AMG through the corner but would pull away heaps on the straight. Can't wait to get tyres though!! Biggest issue I have.
