Good point. Engines are 2499cc, so STU weight would be 2750#, no additions for RWD. Pro3 weight is 2650, so 100# more ballast.

And there's no 1/4" mesh limit in STU (in fact, you're allowed to cover grill openings).

And I'm gonna go out on a limb and guess no one runs the automatic transmission.

So, other than +100#, they're compliant to STU.

Edit: oops, cage. STU requires a lateral dash brace. Pro3 regs require IT- or GT-compliant cages, and the former does not require a lateral dash brace.
