I was offered a set of 5 minilite wheels, 6.5 x 14 at a giveaway price. The only catch is the PCD is 114 (for BMWs)with an offset of 30 mm for rear wheel drive vehicles. A machinist/friend advised me that the stud bolts can be repositioned to fit the wheels. The use of stud spacers is also out of the question since the offset is 30 mm. as compared to the standard 20 mm offset of Volvo for rear wheel drive vehicles. There is no more space to use a stud spacer. My concerns are:

1. Is repositioning the stub bolts to 114 doable and safe?
2. Is machining the wheels from an original 30 mm to 20 mm to prevent tire rubbing on the inside fender an acceptable practice?

Your comments and inputs will be highly appreciated
