Anything special needed for skinnies?

[Beamer]

I am going to keep my eye out for a set of skinnies for track use. I have a set of Centerline Auto Drags with slicks for the track and believe I would drastically improve with some skinnies also verses my 15X7.5's with 245/60 or 70R15's that I have been running.

Is there anything that I need to ensure before buying them with respect to backspacing or anything else? I am looking for a used set and will check on Ebay every once in a while. I just want to make sure that I know what I need.

Thanks in advance,
Mike

How "skinny" are you wanting to go? That's the big question.

Thanks for the links...

It looks like a 3.5" with 1.5" back spacing to a 5" with 3.5" back spacing. That kind of gives me an idea to push away from the rotor about 2" or so to keep a proper fit inside the fender. As for height, I would use 26" to 28", I believe. I am only looking for track time to reduce weight and drag on the ground.

Any other comments are welcomed. I am hoping to find a used set of wheels at least, by the way...
