weld prostar backspacing

[Robuilt]

OK, ive done my research trolling internet boards and have not come to a solid conclusion.

I own a 97 GT and want to buy a set of 15X10 Prostars. What backspacing will be a good fit.

Ive heard a 5.5 and 6.5"

Now remember, 94-98 axles are 29 31/32"s (almost 30"s) while 99-04 are 30 11/16" (almost 31"s).


anyone with a 94-98 running these wheels? what is your backspacing?

IIRC my 15x10 Pro Stars are 6.5 BS.

A lot of good info in this thread http://www.sn95forums.com/forum/index.php?topic=26798.0

I have been told that with 15x10 welds in the rear you will not be able to run aftermarket exhaust, and that you will have to dump...just a heads up. I've always been told

15x8 - 5.5 bs
15x10 - 6.5 bs

Not sure if mine counts as aftermarket exhaust as I have weld in Flows.

I had exhaust on my car with 10s and 6.5 BS no problems. didnt even have to take the quad shocks off...

okay than sorry for the wrong info. Ive been told that before by a different forum, but wasn't sure if it was true.

6.5 will tuck them in nicely. I will be running 5.5s to bring them out to the edge of the fender more. But if the car squats too much then there might be a problem.

mine seem to tuck just fine...

also to be track legal with prostars, you have to have extended lug studs...
