will 275/35-15 tires fit all 4 corners?

lol... with my massive 120whp I don't really have trouble controlling wheel spin under power on standard 215 street tires. More so what I'm going for is more cornering grip in auto-x format. With the A6 tires I won't be able to use them on a full length track anyways (would turn to goo in just a few laps).

Well obviously it's been proven here that 275s fit in the rear. With a small diameter of a 15" wheel, it should fit better then an 18". I have 265's up front with no issues on 18's (but I have 2.5ID springs). Danno fit 275 up front, had to grind off the small brake line tab on the strut (he also ran with 2.5 or 2.25 ID springs). You could make it work. Depending on offset of course. I would count on rolling the front fenders. Good luck!

The profile of the tire has a lot to d o with the width, for example. I have 225 50 zr 16 in front with 245 24 zr 16 in rear and they are about the same width. Tire rack guy claimed that this is due to the differance in the aspect ratio of the tire. Bigger aspect ratio, increased width and contact patch. That tire size is standard for corvette, but corvette has 300 Hp stock, your n/a 944 is less than half of that horsepower - why would you want to do that?

Anyways, as I stated before, the wider tires are not for better acceleration (though it still may help in some of the slower corners), but more so for lateral grip & braking.

Just so you know a 225/50/16 means the tire is 225 MM's wide, the sidewall is 50% of the width (or 112.5mm's) and the rim size is 16". Contact patch can change based upon rim widths but it's not a significant change as a percentage.

Umm what the hell are you talking about. Width is width. Aspect ratio is the relationship of the tire sidewall size in relationship to the width. A 225mm tire and a 245 mm tire are still going to be 225 and 245 mm's wide regardless of the aspect ratio.
Just so you know a 225/50/16 means the tire is 225 MM's wide, the sidewall is 50% of the width (or 112.5mm's) and the rim size is 16". Contact patch can change based upon rim widths but it's not a significant change as a percentage.

225mm = 8.85826772 inches
275mm = 10.8267717 inches
225/45-15 = 8.8" of tread, 9.8" wide on 7.5" rim
225/55-15 = 8.7" of tread, 9.6" wide on 7.0" rim
275/35-15 = 10.1" of tread, 10.8" wide on 9.5" rim
275/50-15 = 10.0" of tread, 10.8" wide on 8.0" rim
As you can see the 225's do have roughly 225mm of tread, but the tire is actually another inch wider. Whereas the 275's are roughly 275mm wide, but have about 3/4" less tread. And that variance is only among one brand/style, when you mix brands it's even more inconsistent.

While you're mostly right, another thing to keep in mind is that 225 is not necessarily 225mm of tire. For instance, the specs for that A6 tire are:
225mm = 8.85826772 inches
275mm = 10.8267717 inches
225/45-15 = 8.8" of tread, 9.8" wide on 7.5" rim
225/55-15 = 8.7" of tread, 9.6" wide on 7.0" rim
275/35-15 = 10.1" of tread, 10.8" wide on 9.5" rim
275/50-15 = 10.0" of tread, 10.8" wide on 8.0" rim
As you can see the 225's do have roughly 225mm of tread, but the tire is actually another inch wider. Whereas the 275's are roughly 275mm wide, but have about 3/4" less tread. And that variance is only among one brand/style, when you mix brands it's even more inconsistent.

Three Wheelin'
Don't remember how low your car is, but since you're running CSP the wheels don't have to stay completely under the fender. You can run whatever offset you want and have the wheel stick outside of the fender. The only issue would be if you would rub the top of the tire in the corners. Shouldn't be any issues with rubbing on the inside of the tire if you have enough offset.

Hey hold up, I was only reiterating what the Tire rack sales guy told me on the phone when I shopped tires. I couldnt understand why the aspect ratio related to the width either, but what he told me made some sense and he did mention that manufacturers vary on the numbers. I think the 225/50 and 245/45/15 sets are pretty common for the 951. I remember my vette took the 275/40/17 on all 4rs. I also remember for example, falken made a wider tire than goodyear due to the lip protector they build in to the tire bead.
