Can anyone tell me the correct offset for 18x8.5 front and 18x10 in rear wheels for use on a dedicated 968 track car?

Don't remember offset but they are 997 wheels and they fit with some negative camber in front.

Dave,

I have 18x9.5 and 18x10 CCWs. The 9.5 fronts have a 7.5 inch backspacing and the 10s have an 8 inch. No issues with the rears at all. The fronts have to have at least -1.8 deg camber to clear. The tires are RA-1s: 275/35 and 245/40.

Mike,

You have 245's on 9.5 inch rims? Seems like you need more tire, friend.

Well, I wanted to give the installer a challenge! Actually, the tire is rated for that wheel width and it will stiffen the sidewalls a bit. It doesn't look like I'll get any track time on them till next year so we will have to wait to see how they do. I think there is room for 255s if need be.
