The range of tyres up in that width is pretty limited. It seems to jump from 275 to 315 with nothing much in between. Are you running the Kumho KU36? I'm looking forward to running in the new control tyre classs.
I agree with Dave. The stance on your car is great. A real credit to you.
I don't think the symmetry on the original cars was anything to write home about either.
The bump on the rear of mine was so bad it wore a hole right through the fiberglass in one spot
Probably would have cleared with 10" rims though. There was a change in toe of more than 20mm through the entire travel.
When I modified It I had everything bolted up and checked clearance through the whole travel. Fingers crossed there will be no rubbing. That sort of thing really irritates me.
Cheers
