My 68 911 has a 930 slant nose wide body kit, the wheel that came with the car has to be replace ( wheel not wide enuff plus it does not look like its even a porsche rim, it look like somthing off a Fors Van) I want to replace it without the use of spacers. Its seems like I can go has wide as 10 - 12 inches wide X 17. My question is How wide can I go on the rear (17 X ?), on the front (17 X 7" or 8), ? and What will be my offset on all four Rim? Attach is a pics. CAN ANYBODY OUT THERE HELP ME?????????
