Only -1 degree camber for a Roval?

I have heard that some road racers will change their camber for road race tracks that include a long NASCAR bank.
The concern is too much negative camber creating a hot spot on the tire. In fact last year a tire rep said he thought a 911 that hit the wall at Fontana may have had too much negative camber and overheated a tire.

I have two races back to back this spring on the NASCAR banked roval. I was told to run only -1 degree camber on the outside tires.

Does that sound right to you?

I would of thought it would be the inside tires that would require
-1 degree camber?

You need tire temperatures. If most of the turns are in the same direction, you'll need to experiment a little to see what will manage your tires the best. When I used to race at LRP (6 right hand turns and 1 left), I used to take some corner weight off of the left front of my FWD Mazda 323 which helped a lot in the right hand turns and reduced the tire temperatures of my LF tire noticeably. Of course the car wasn't so happy in the left.

Alternatively you can play with the pressures, shocks, springs and or camber. An asyemetrical set-up may be needed like an oval car where the outside front may have -2 degrees of camber while the inside front may have +1 degree or something like that.

But you won't have a clue what works and what doesn't without a pyrometer.

I know that Goodyear race slicks like close to zero degrees of camber.
