315 tires on e31 850i

[ZERO NERO]

Alright people i want to ask everyone here in the forum for help , advice and guidance into making 315 tires fit on the rear of my e31 ! I know it is possible because a few bimmerforums members have done it while playing with specific offsets and different tire brands i currently have on the car 18" oz racing wheels 8 front and 10.5 rears and i am running michelin pilot super sports 275 without rubbing ! Any help is greatly appreciated also might go 19"
