What size are the factory wheels?

[Steve Petro]

I know its a stupid question but...............
What is the WIDTH and BACKSPACING of a facory 1987 Grand National wheel. I thought the width is 7". I tried to measure it with a tire on thru the opening and it "looks" like 8".
Thanks in advance.....................

If you point to the underlined text, your browser should show the link path at the bottom of the page in MS Internet Explorer. With your cursor over the underlined link, just right click and pick Properties, and you could copy and paste the address in your browser. I just tried the link and it worked, its in tech articles of gnttype.org under suspension. Here it is in long form, it's got all the info you were looking for.

Other than changing the suspension enough to keep from dying, has anyone actually topped out a stock TR between 156 and 162 MPH?
