Hello,

I have an 87 RX7 that I have been autoxing. Last year I ran the car with convertible BBS wheels. I am looking to go with a wider wheel this year to compliment a set of 225/45/15 Hankook R-S3's. I was thinking of going to an 8" wide wheel since the class I'm running in (SM2) has no limitations on wheel width.

I need to know what backspacing I need for the car. It has a full ISC racing suspension setup on it(including adjustable front bar) and the ride height is setup per ITS rules (5" from lowest point of rocker panel)

I was thinking 5" because I was told that would work on a 7" wide wheel. But I don't know if the extra inch of width will cause problems...especially in the front where I know it will be tight.

Here is the wheel I was considering going with:

I also have 1/2 spacers and long studs, and I'd like to still be able to use them for setup purposes too.

Thanks for the advice in advance.
