After looking hard at fitting 7"x 15" alloys, I've about concluded to go with 6" x 15" alloys. My 5 1/2" x 13" factory alloys have an offset of about 26 mm and a backspace of about 4 3/8". The 6" x 13" aftermarket alloys on the car have about an 11 mm offset and a backspace of about 3 7/8". It appears to me that a 6" x 15" rim with a 15 mm offset will have a backspace of about 4", giving a little more clearance on the inside than the factory rims and a little more clearance on the outside than the aftermarket rims. Moss Motor's wheel information page seems to confirm my thinking, suggesting the 6" x 15" rim with a 15 mm offset. Am I missing anything before I put my cash on the line? Thanks.
