BFG G-Force R1 application notes
 

I am about to install 205 and 225 R1s on my track car.

(23/31, lowered, polybronze)

Any suggestions on starting camber settings and hot pressures?

Cheers

We've run these only a short while on a friend's car- 87 Carrera 23/30 springs, adj. rear bar, 225 front, 245 rear.

We run max camber that the rear springplates will allow (with the use of the Elephant Cambermax widgets) and started pressures in the low 30's. They climbed pretty high so we settled them back at mid 30's and they seemed to do okay with wear and grip. However i'll admit said friend is one of those set it and forget it kinda guys. Half the time he doesn't know what's a good tire pressure and adjusts his driving style (balls-out sloppy lines, but still drives the crap out of the car) accordingly instead of playing with the pressures.

The fronts have the camber (-2)and caster maxed out for the stock camber plates. Shoulder wear is prominent, as is heat (shoulders turn blue when in storage). Same tire pressures. Mid 30's work well. However raised spindles and more camber are in the works to get better results up front.

Forgot to mention i'll likely use these this coming season, so i'll post my personal experiences on my own car.

Mid 30's like they tell you, as much negative camber as possible. Great tires.

To answer my own question ;)

32 F, 34 R hot

-3 neg F and R

Yeah ,I remember with my old r1s the pressure would go raelly high after the first run group. Nitrogen is supposed to help the stability of pressure though a lot of tire shops and off road chassis shops( shocks) have this.
