Anyone that saying the class name changed to just XA or XB care to post which Fastrack it was addressed? I've looked over the last three years and don't see that mentioned once. Maybe I'm missing it?

This thread died but hoping it grabs the right attention. Is anyone running the 275/40/17 RT660 on the rear? I'm not prepared to quite do a rear gear ratio change and was hoping these should fit without much work.

depends on wheel offset. +42-45 should fit it easier than say a +38 would. I barely made my 275 hoosiers fit in the back on a +38

Thanks. My RPF1s are ET45 so that would be easy to do.

pumping this thread again. So since i took forever to get all my stuff together it looks like they changed the rules and i cant run a difuser. Would that mean that I can't even put a sheet of something over the big gaping void of where the OEM muffler was? pinging @Chuckls

I sold my FRS but I'm still putting together a different XSA car. The aero rules are going to change and according to the FB group, we should have an idea of the new rules earlyish December.

The current and soon to be out of date rules have a loophole for the diffuser, since it says 6" forward of the rear bumper and that includes the bumper piece just behind the rear wheels in most cases which allows a true diffuser from most OTS offerings.

I was wondering about that because i verus diffuser would probably fit the rules if you get the "non aggressive" one

The Verus rear diffuser fits the loophole ruling no problems.

I wish I were more help, but I've moved on from XSA. HPDE Champ #1 now.

I want it for track use as well. I'm worried they might tighten that up but get more loose on wings. So, I wait.

I'll sell you my tS wing. It fits XA rules

No thanks. Even if I wanted it, it wouldn't work on my car. I sold my twins.

Just bumping the thread to see what everyone is doing this year.

I did it for the first couple of events since I installed Flex Fuel in the off season. Ultimately I ended up just moving to ESP since the PAX is better on that and I had an opportunity to have a bit of direct competition with someone running along in that class in our region.
