Default Tire question

Okay, a buddy of mine has a GXP and is completely sick of the mismatched tire sizes for some reason. I was going to order him some new tires for the car but before we buy 255s for the front and 225s for the back I wanted to see what size the rims are.
Also, i'm always looking for new customers. I dont' have a LS4 section in on my site but I can cut you guys some good deals on parts.

18s, I think they were 255/45R18 and 225/50R18 stock. I'm running 275/40R18s and 245/45R18s at the moment.

Thanks for the quick answers guys. As far as LS4 parts are concerned I'll work on it if there is enough business to warrant it. I guess you guys don't have a ton of options like the Vette and Fbody guys. If you guys need anything in the mean time just shoot me an email and I'll get you a solid price.

Right now we have your main bolt on parts. Intakes, exhausts, tuners, etc.., I can get pretty good deals on rims to since I have an account with the Tire RAck. So anything there I can get for you at a discount. But there isn't to much I can't get my hands on at this point.

Ok then, how about a Magna Charger with an approximately 10mm shorter snout than standard LS motors and a rear mount throttle body?

Yeah, probably can't cover that one. Did you try bolting up a Maggie set up for another car and it not fit? I wonder if the snout from a L67 blower would fit, I'm sure that's gotta be shorter. Seems like a long shot though.

You could add a section for MAFs, intakes, camshafts, headers, etc.

From fieroguru:
LS4 78mm MAF on the left and the 85mm [LS2] MAF on the right. Both are 5 wire MAFs, but use different connectors.

EDIT: And considering that your friend has a GXP, this should all be pretty much straight forward.

Is the GXP's wheel well really that different than the Impala's? I have 235s in the front and when my wheel is cranked all the way left or right the tires rub in the wheel wells.
