Can't remember were but I read Toyo recommended 2+ degrees of camber heres the reply from their competition and technical manager for any-one interested
Hi Tony,
The amount of camber will depend on the tread temperatures. I normally suggest a starting camber of around 2 - 2.5 on the front and around 1 - 1.5 on the rear and then see what the tread temps are doing. You should be looking for a maximum spread of 9 degrees C, coolest on outer edge.
If you would like to discuss further please give me a call.
Regards
Alan.

Gotta be useful for a baseline, ta for that.

Tony,
Did they give you an optimum temp to aim for.
I think mine were running a tad hot at Oulton as the rubber was rolling.
I was running 18psi cold which may have been a bit low.
