Here's some info: The tires were mounted on either chrome-plated steel wheels ('86/'87 GN) or ribbed aluminum wheels ('84/85 GN, '86 T-Type & '87 Turbo-T). There were other wheels available for other turbo-packaged Regals but these are the two most common styles. Both styles were 15"x7". '86/'87 GN wheels had a 3mm negative offset and 4" of rear backspacing. The aluminum wheels had 3 3/4" of rear backspacing. The circle bolt pattern was 5 X 4 3/4 inches. Hope that helps |
