Wheel sizing info needed
 

Hey turbo guys, I am having a set of 17's made for a 78 930. (well a car converted to widebody but using 78 930 front hubs and full 930 brake package). We want to put wide wheels on it but need some offset info. The car has front coil overs so we are losing between 1/8 to 1/4 inch of clearance up front on the inboard side. Do not want to run spacers. What are you guys with 17's running for offsets? Would like to fit a 9 in the front and maybe up to an 11 in the rear.

Thanks

Anybody know the offset of their aftermarket wheels??
