Hmm, that is really interesting though. I need to check SM rules and see if I can clearance the inner fender walls. Ive refused to do 315s because I don't want to make the rear wider. But inboard.... Maybe I have a new project for winter.

FTFY. Unless your motor build is gonna happen that quick..
Motor will be ready before Nats this year. I getting pulling a 4G64 block from the JY Saturday and will drop it off at machinist next week. Picking up all the parts I need in stock from ER as well. If I get really lucky I might even make packwood Tour/Pro in July.

As I understand it, nothing inboard of the hub face per SP rules. SM only modifies to allow replace/modify of fenders, not the body side of the fender well.

I assumed this was covered in 16.1.O:
"Any minor modification, intended to allow or facilitate any allowed modification, is permitted as long as it does not provide any intrinsic performance benefit in and of itself, does not provide a weight reduction of more than 1.0lb., and is not explicitly prohibited elsewhere within these rules. This rule is intended to allow minor notching, bending, clearancing, grinding..."
This gets us into the subjectivity of "minor", however. For instance, I'd think taking a BFH to a couple problem areas could be considered "minor clearancing"
Also...I'm wondering how the question of how to fit 315s is just coming up. Shoe has been doing it on 18x12 for 3-4 years now, and others did it on 18x10.5 before him. R/TErnie trailing arms were the ticket before Wisefab.
Here are mine... still waiting for the motor to be ready so I can get the car back and work on suspension stuff.
I was actually considering trying a 335, since it's the same diameter.
That an 18x13? 315s almost stretched looking there.
The question is can they be fit under stock rear body panels. If I can get rear to fit with some cuts inside, I may actually consider that route. Need to write a letter...
I don't necc turn full lock during track days so 1-4 mm of inner front rub is ok but annoying. What I do need is for it to "fit" without cutting the inside like Andy had to do in the rears - or to not be able to run ducts because i'll roast the brakes without em on these 90+ deg day races. R/T arms are on. Current wheel that's even close is a 18x10+38 RPF. The real question at the end of this is - is it worth going that wide with the high mph I have to see....Sebring...Road Atlanta...VIR...Roebling... aren't the most technical tracks. Tis been my debate all along:
1. 275 most power
2. 285+ mid power
3. 275ish slick least power.
By far the slick has been the fastest....but it comes with a cost....both in in $ and if you go off you're in for a ride.

Ah...fitting the 315 w/ stock(ish) panels would be tough. I've given up on that idea. Those wheels are 18x12 +20 Volk ZE40s
Looking at the inside well of my rear fenders will definitely show that even a 285/295 will both rub a fender and inner fender well. And my fenders are pulled about 20mm all around. So either you have to start cutting inside, those tires run narrow (not likely), or fenders are even more heavily massaged than mine.
And as has been said about the front, The trans is definitely a limit for steering angle. Hard to move that guy. Though you can just steer less and its possibly fine on track. AX would not work though.
front steering was limited. no full lock without rubbing. This could be an issue for autocross but typically road course you are not doing those tight turns.
Also for what its worth, we are NOT sponsored by wisefab. Its a good kit for the money but there are some issues that need to be resolved.
The clearance to the suspension spring is closer than to my R/TErnie trailing arms. So, the big swoop doesn't do much unless you also offset the rear coilover (or run a short spring which will get you 6mm)
Is the coilover mount on the Wisefab rear LCA more inboard than the stock LCA?
Also, my point was more directed at the front where I stated that they likely can't turn the steering wheel too much.
Andy, the question that came up was: How exactly does the WF susp allow for the wider rubber?

A little info on how this even happened. We wanted to run wider tires than 275s since we noticed the 275 Falkens compare to 275 Rivals would get up to temp quickly. We figured running wider will help spread the load and stay

Yeah, road course certainly isn't using full steering and if driving on the street or AX you could just put back on a narrower set of tires. Heh we all get a little too excited at thinking their might be a way to fit 315s under stock body but their is no free soup. Even my 295s required somewhat significant effort on the fenders and wheel wells.
Hell, half the reason I made the billet control arms caster adjustable was to perfectly center the wheel for rub (work amazing btw).
