So what are everyone's thoughts on specifically the wider wheel/tire allowance for STU in regards to the Evo 8/9? Will this alone make this platform not nearly as competitive? I mean I know we could fit a 295mm tire up front, but out back that's a different story.
Unless one would run 18x10.5 or 18x11's all the way around, run high enough ride heights out back to "fit" that by just letting the rear wheels/tires poke and not give a F?
Thoughts? I'm all for the clutch, boost control, FMIC changes no doubt. I am torn between the wheel/tire situation.
If all else fails, my friend recently bought Ron Bauer's SSM ND Miata, so I may just co-drive that next year instead.

So STU allows us to run up to 11" wheels. That being said, here are my thoughts/options:
1)
Front:
10.5" or 11" wheel
285mm RE71R
Rear:
10" wheel
285mm RE71R and see if I can get that to fit. I think it's possible with the TC105X's I have. May have to increase rear ride height even more...
2)
Front
10.5/11" wheel
295 A052
Rear
10" wheel
265 or 255 with a similar OD to the front
3) Poke for days setup. It is legal to have tires poke out from the fenders in STU, right?
Front
11" wheel
295 A052
Rear
11" wheel
295 A05s
Discuss.

There were some pinching 275s on stock 8" wheels back in the day but the tire definitely fit under the strut up front and a pinched 275 was probably more like a 255-260mm tire. And then with the fender clearance from ride height it was still probably rubbing/hitting at heavy load.

I wouldn't run the staggered wheel widths. a 10" wide wheel is fine for 285's, no reason to run the wider front wheel and not be able to rotate the tires.

However, my biggest reason why I'm leaning towards the 295mm AO52 (11 inch wheel up front) and the 255 AO52 (10" wheel out back), is with how much wider that 295 tire is compared to the 285mm RE. That and the RE71R is out of production with no successor named as of yet...
295 A052
Section width 11.8"
Tread width 11.2"
285 RE71R
Section width 11.4"
Tread width 10.3"

@Dallas J will tell you the staggered setup with wider fronts has been tried and it doesn't work.

I've read his comments on it before, and to summarize- you don't want to sacrifice rear grip in the hunt to reduce understeer by running a larger tire up front. At least thats how i recall it being phrased.

As long as you're respectful, thoughtful, professional, and operating with good intent then of course it's fine to weigh in on classes you don't currently participate in.
