Can someone tell me what the offset is on the 16" Snowflake wheel that was stock on the 1987 and 1988 Turbo Coupes? I'm looking at some Eagle Alloy 192's to replace the stock rims and have been told that they will fit. Eagle Alloy now offers a 4X4.25 bolt pattern in this style of wheel. The offset on the 192's are +32.mm.
I'd say that +32 on 7" wheels should be fine for an 87-88 TC. Don't know the offset number of the factory wheels, I'm going to guess that they wqere around +35 to +38. I do know that they had about 1/4 to 1/3" more rear spacing than Fox Mustang 7" wheels ... because I used 1/4" spacers behind 88 TC wheels on my 87 Mustang way back when.
