Another stupid wheel fitment question!
A friend of mine has a set of 15x10 prostars with a 5.5 backspace. Should I bother buying them? I don't mind cutting bumpstops or removing extra metal inside the fenders. It'll probably be a 275 drag radial on them. Thanks!
-disclaimer. Could not find an answer in search. Once saw a prostar thread but I couldnt find it.

Re: Another stupid wheel fitment question!
try harder, this is a very common fitment.
they will bolt on with little modification, provided they have the right bolt pattern.
they will, however, stick out of the wheels wells a little. this is a very common size for the drag race guys. 6.5" of bs looks a million times better, but require more work, cutting, hammering.

Re: Another stupid wheel fitment question!
You will need to cut out the bumpstops and I had to grind the **** out of my pbr calipers to make them fit, yet the '87 iroc I took them off of had pbr calipers and didn't need any grinding or cutting of bumpstops just unbolting, apparently there are two different kind of fins on the calipers and mine had to get grinded.

wheels design has a lot to do with the fin issue as well

Re: Another stupid wheel fitment question!
I took my draglites off of an '87 iroc with pbr calipers and they fit fine on that car with just the bumpstops unbolted and calipers intact. I put them on my '89 iroc and I had to cutoff the bumpstops and grind the snot out of the calipers.

Re: Another stupid wheel fitment question!
regardless, every car is a little different, so some may need a little more work than others. the rideheight can change this since the axle will move side to side at different heights because of the panhard bar.

Re: Another stupid wheel fitment question!
Dont forget, brake pad thickness in the rear will affect where the caliper sits in relation to the back of the wheel.
Old pads will give lots of clearance, new pads will make the caliper require the most grinding.
Ask me how i know...lol
I currently run 15x10 with 5.5bs...with factory wheel wheels, didnt have any clearance issues.
