yes speedle i just notice that a good spot mate even mine are odd.
not so much on mine but the bigger engined fwd cars run something like 16/17" front and 13/14 rear and the mid engine cars run 15/16" at back and smaller at the front.
but when youre going sideways at 80mph with a 200+bhp car wheels are the last thing you think about....lol
i bet who caes what it looks like as long as its fast must go to one of these races next year, thats my new years resolution perhaps we could make it a south meet if they do that down our way
