18x10.5 +30. Front fits just fine without the need for a spacer. Rear needs a MAJOR pull/roll. If you run the SSB rear trailing arms, there are guys getting away with just a roll with the 18x10.5 + 38
and for folks here that might not be super familiar with the STU rules, neither fender pulling or the rear replacement trailing arms are legal in our class.
Stock diameter *and* stock thickness I believe (to avoid those Girodisc ultralite things)
edit: 14.6.A
I don't know if that's true any more...
Here's the OLD SCCA wording for STU:
Non-standard brake rotors may be used provided they are of equal or larger dimensions (diameter and thickness) and made of ferrous material (e.g. iron). Thickness includes the individual plates
of a vented rotor, as well as the overall dimension.
For 2021 - Now the rules only talk about diameter and rotor thickness, which the Ultralites technically have the same OD/Thickness as an OEM rotor. Someone can correct me if I'm wrong here, but I'm quite certain they are legal currently given they dropped some of the wording of old. The wording for ASP brakes is exactly the same as STU and I know there are evos running these in ASP at a National level as well.
On a side note, it seems Girodisc is no longer making these variants according to a few websites....

Doug, excellent clarification! You are indeed correct and I could see how since I posted that in this STU thread, it could be misconstrued as being legal, which it isn't. Thanks!

This may be a rather obtuse question however I am new to the STU ranks in an Evo. My car has no rear spoiler, is that something that I need to rectify?

I've gotten some feedback. Figured I would take it here (suggested) to get more viewpoints. Is everyone going out and upgrading their intercoolers or is that a low yield upgrade? Seems our runs are so short that heat soak and timing being pulled would not be an issue. Thoughts?

For me, I was updating the car for the new rules and wanted to get all the power stuff done at once so I could get it tuned once and call it a day. (opted for the 3" ETS so nothing crazy - 24 lbs). It is more weight up front (though it's low, at least) and at these power levels I don't think you need one.
