#78163 I want to buy 4 track R's for doin trackdays as the circuit10's are 6.5's
and less gripy SO . . .

ROTA are doin track R's (sprintheart cp-R's) in a 15x7
they have two offsets though +40 an a +15 ? :?

Which will be more suited i.e be enough to fill the arches yet not too much
to have to pull out arches . . .
NOTE: the car will be alligned for the track before running negative
camber . . .

#78169 the +15 will need some light body work (fender roll) done to avoid rubbing, but it also depends on the size of tire you are going to run, how low your car is and camber.

You will be safe with the +40
