Has anyone ever measured to see just how much more inboard room you can use up before hitting the struts in the front? I've found some wheels that really look nice, but the least offset offered is 35mm and stock's only 10mm. Would that extra inch or so justify a spacer?

 

Depends on what year you have and what size wheels you plan on using. For the 84-86, the largest backspacing you can use is 5 inches although that is virtually touching the strut housing. For 16 inch wheels, I wouldn't recommend anything more than 4-3/4" as you would probably rub with more than that. And then you can't run tires much wider than the wheels or else the tires will rub on the housing.

For the 87-89, you can run a little larger backspacing, but I wouldn't go more than 1/2 larger for a good safety margine.

 

It's an 86. Before I get my ruler out, can you tell me what the stock wheel backspacing is? Thanks.

 

Read the bottom of this page to calculate backspacing:

The numbers used to calculate the backspacing for all stock wheels is at the top of the page.

 

Page down key, basic math and metric conversions? You sure want a lot.

Wheels I'm looking at only have another 9/10 of an inch so I think I'm safe. (4" total)
