This may not be the ideal place to ask this, but....

I'm close to deciding on buying an 05 GT, but i'm wondering if my 18x9 and 18x10 FR500s will fit on an 05? Looking at americanmuscle.com, they have wheels that fit on 05, and not 99-04, so idk if it works the other way around too. I've seen a pic or two of an s-197 roush with them on in the 2005+ talk section, but idk if you need to modify something to make em work. If they don't work, i may hafta dump my fr500s on someone, and pick up the gt500 replicas. Thanks in advance.

ok, so how did this guy make em work? Do they make special fr500s for the s-197s? can you just use spacers or something?

i know its a diffrent back spacing. to get 05+ rims to work on our cars you need a spacer. but for our rims to work on 05+ i really don't know.. it would be a cool little thing to try..

LOL not that bad haha...but they don't look right, for sure. I bet you could find a wheel machine shop somewhere in your area to mill down that offset to fit an 05+ better! My guess is wouldn't cost more than $40/wheel max....

it'sd be best to use a C&C machine and anything from those places is $80 starting

C&C would be the more accurate, but there is no reason why it can't be turned down on a lathe IMO. There are plenty of shops that make custom forged wheels w/ lathe (as well as C&C) processes from scratch, so they shouldn't be too hard to find no matter what. Anyway, to the original poster, if you're dead set on that exact set of wheels (doesn't sound like it though!) then shop around for wheel/custom machine chops, otherwise sell them for some decent coin and buy what you want for the new whip

Ok, i'll admit right now that i don't know much at all about wheels, but i'm also an engineering student, so i had to do some math. I found this diagram, i'm assuming its a universal schematic for most wheels.



Then I looked up the specs for the FR500s i have, and the back ones are 18x10, with a 22 mm offset. The shelby gt500 replicas i'd get are 18x9.5, with a 50 mm offset.

If i'm thinking about this right, the distance from the mating surface to the outside edge of the wheel is the offset plus half the width of the wheel???? If i do that, i get that the gt500 wheels are 6.7 inches, and my FR500s are 5.9 inches, which means they'd be tucked further in than the shelby wheels? This contradicts what people are saying. Am I completely off here?

EDIT: I just realized this, right after i posted it.....it depends on which side is the outside. At first I assumed that the right side is the outside, is that right?

ok, i'm a retard. I found another diagram that is better. I assumed that the outside was on the right of the above diagram, when its on the left, that reverses it, and now i got these numbers...

the shelby wheels would be 2.79 inches out, and the fr500s would be 4.13 inches out, which means my fr500s would stick out an additional 1.34 inches.
