tell me I'm stupid if you want, I dont mind. but a thought has just crossed my mind, thinking back to when Halfords fitted the wrong tyres to my new 18" alloys. they should have fitted 40 profile tyres, but instead they fitted 35's. it doesn't sound a big difference, but apart from it affecting the speedo, the car accelerated like a standard impreza......... pathetic !! what would happen if you fitted oversize tyres ?? onder: I know it would confuse the speedo again, but 2 things ; there is plenty of room in the wheel arch for . lets say for example 215/50/17, instead of 215/45/17 or even 215/55/17 !! :cool1: [ and pro rata for the 16's & 18's ] and also only for track days ?? not very practical for every day use.
I'm not really one for trying experiments, but I know a man who is !!! [ Dave...... are you listening ?? ] I reckon a scout round for some cheap, second hand, oversize tyres, [ the engine has enough power to overcome any quirks you might throw at it ] & I bet you would reduce your 0 to 60 time by................................................ . waits for ridicule !!:nono: 0.5 secs !!:cool1: :cool1:
