I'm ordering up some new wheels for my heap. I see all this chit about wheel specs and the only thing I can ask is "WTF?"

The wheels are a 15x8.5" wheel if it makes a difference.

I'm pretty sure I need a 5x4.5" bolt pattern, correct?

My question is about backspacing.

The wheel is offered in both a 3 3/8" backspace and a 5" backspace. Can I run either the 3 3/8" or the 5"? Which would look better? Would one have a dish to it and one wouldn't?

This stuff confuses the hell out of me.

Thanks for all the help.

Pro stars? I'd ask Jesse, he's got them on his car.

Na. I'm trying something new (I think) - Convo Pros.

Anyone have any ideas?

Your right on the bolt pattern..

Out of those two backspacing choices you will want the 5". On my weld prostars (15x8) i have a 5.5" back spacing. Has a nice lip to the rim.

Definitely want the 5" BS -- I wish Centerline would make that size with a little more backspacing so it would sit inside the wheelwell better.

Stock backspacing is around 4.75" as best I can remember, so going to a 5" BS puts the 1.5" wider wheel about 1.25" further out than stock -- not bad. If you went with the shorter BS, the wheel would stick out about 4" further than stock -- not even inside the wheelwells. I'm not even sure why they make it, I can't think of any time you'd ever run that.

Good deal.

I've got one more question. Are you guys running any type of spacer in the rear to make it look a bit more appealing? I've been thinking about running them even with the stock ponies and I figured if I'm buying new rear wheels, now is the time to put some on if I want to. If you are running them, what size is best to go with?

Thanks for all the help.
