how high will 18s raise your car?
 

So i have this buddy of mine that has a v6 stang, and i talked him into getting 18 inch bullitts, but hes concerned about how big of a gap will there be between the tire and the fender as in hight untill he gets lowering springs?, will it look like a 4x4 stang or will it look decent enough to drive around with untill he gets lowering springs?

It will look almost the same...even though the rim is a little bigger, most likely he will get some lower profile tires like 35's. I swapped for the 18's and now I hit on the speedbumps going to work, so I know the car sits a tiny bit lower.

it all depends on tire width and aspect ratio

Exactly.My setup is almost the stock hieght.

35 series
 

He should run 40 series up front and 35 series out back - 275's on both sets if he wants to be able to rotate (assuming he didn't get 10's out back).

Some people are running 285's front and back, but they scrub on the front just a little in tight maneuvering.

Isn't that backward? Wouldn't you want the 35s up front and 40s out back? Plus, wouldn't that also eliminate the ability to rotate? I mean, the width would be fine, but why would want to rotate with different ratios? One time, the rear would be up a little, then the front with each rotation.
