Doesn't seem like it

 

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.

 

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!

 

It wouldn't be the first time!

 

Good catch - I forgot about the older wording. I agree, I think they'd be legal if you could find a set. They would make great rear rotors..

 

No problem! Glad to clarify.

 

Hey Dallas, you got a picture of that to share? Tasha just handed me her credit card :-)

 

If you zoom in you can see its slightly pinched.

 

Just a little bit happier

 

I think my car would be much happier on 315s with 18x12" wheels

 

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?

 

You can definitely remove the stock wing in STU!

 

Outstanding, thank you! I creep the STU threads a lot to figure out how to set up the car. Enjoy following your adventures.

 

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?

 

FYI - there's a 2022 thread

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.
