I went w/ her to order her some rims for her 98. I read on here that 17's are a really good choice, however, she wanted chrome "twisted 5 star" rims. The place we went to didn't have any that would fit. So she picked out a set and they are 18 X 8 Or 9 I cant remember. The tire size is P245/40/r18s (Z rated). I know most (or all) are against these rims but I just want to know how bad this will hurt street performance?

Since the overall diameter will be the same as stock will I need to upgrade the brakes (or brake pads)?

I am thinking of maybe pushing them out 1/4 of an inch. Would this be too much?

I think I can still drop the car in inch (maybe an inch and a half) good idea? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)

Cal, the one problem I've seen with the 16" wheels... no clearance for big brake kits. That being said, I wouldn't go beyond a 17. I know you mentioned NASCAR, but I would assume they don't have as much of a problem with tire roll as autoxers would, do they? In that case, wouldn't a 17" wheel with a shorter sidewall tire help prevent tire roll?

Yeah I think allowing bigger brakes is the only advantage of bigger rims. But for "Mom's car" doubtful that will be an issue. Plus, LS1 12" rotors still fit under a 16" rim, and are pretty substantial brakes. You need to duct air into them for the big track anyway. AX isn't an issue because there isn't enough time for them to get hot.

For AX, you won't get tire sidewall roll over with good tires like Hoosier's on 16" rims, unless the front end doesn't have enough negative camber. I get zero roll over with 275/45-16 A3S04's. NASCAR runs tires with stiff sidewalls and adequate camber also.
