Can you post a link with more rule details. What's the PAX for Stu?

Here is the new PAX for 2021- https://www.solotime.info/pax/

315s are enticing, and it's nice that the class essentially allows all the bolt-on mods but doesn't encourage all kinds of cutting up and gutting of cars like CAM does. OTOH, the problem is the class also includes that AWD boost buggies and the mid-engine sports cars like the Cayman. The pax index reflects that (STU = .828 vs CAM-C's .818). That said, if you try it a lot of us will be watching!

I'm interested to hear why you'd choose to run in STU over CAM-C?

In reply to the above, it would technically be more limited prep compared to cam. The discussion of the 315 Rwd allowance was one of the final triggers for me to jump out of stu. It will completely change what cars can be more competitive now as there are a lot of rwd cars that can't mount a 3-series tire without fender modifications.. which aren't allowed in street touring classes (rolling only).

This is also probably the only year to try it as 2022 the supra and m2 cars will probably be moved into the class. Quote:

Also PAX isnt a selling point for me. Yes locally its fun if you don't have anyone in a class with you but at nationals its irrelevant. CamC is the easier class pax wise for sure. |
How would they know if you had a diff tune?

Having come from many years of running STU in an STI (typically outrunning CAMS), I don't see the Camaro being competitive unless you can get the weight to 3400 or less and use all of the tire allowance. In that case, CAMC would be easier to do than the much more restrictive STU rules. Tire:weight being most important, but power:weight coming in somewhat closely behind. Big factor being weight. Adding tire width is a good step, but removing weight from the car in an STU legal manner will not be easy. Also, will 315's on 11"+ wheels really fit up front without modifying the fenders?
