Can a 18" fit an ISF? Looks like 18 would be the smallest.... 17 probably a big no go... I'm curious because I would like to pick up another set of track rims for lapping days and I'm wondering what the smallest sizes I could use would be....

I can verify that a 17 from a cobra mustang will fit the back of an F

SCCAForums ran 18s on all four corners without issue. Enkei PF-01s 18x 9.5 with a +45 offset running 285 Hoosiers.

I believe OEM 18" Gspiders fit on the F.

18" fronts, 17" rears are min size. I run 18" Volk RE30s for my winter setup. Even though 18's fit, make sure you have clearance for the brakes.

Cool thanks guys, can you tell me what gspiders are? Are they an OEM or aftermarket wheel?

I was just going to pick up a set of enkei's maybe RPF1's since they are light as hell...

What exact cobra wheel is it would be nice to have 17 in rear for a drag tire opens up alot more tires at much better prices.

If this is what you are talking about, it would be cheap and could accommodate a set of 245/45R17 Hoosier D.O.T. Drag Radials well.
