Get a body shop to roll the fenders then. Also, what is your desired trap speed and what rpm are you comfortable trapping at? Because with the 28" tire it looks like you'll be able to trap around 140@7k rpm. And around like 120ish around 6k if I remember correctly. If you go with the stock height you'll be trapping like 120 or so at 7k.

7.5" backspacing is not very common because they would hit the quad shocks/ and exhaust if they were there. And with so many people just putting on wheels and tires without suspension work it is not a common demand. The inner fender actually has a lot of room to move the tires in.
I run 27X10.50X15 with 6.5BS and they come very close to hitting the fender lip with the car only slightly lowered. When I get C/O's on it and put it to the ground I am going to have to use 7.5" BS wheels or narrow the whole rear end to be able to fit a taller tire.

What Brand and kind of tire? Some tires like Hoosier the sizes are quite a bit different than other brands on actual sizing specs. On stock springs though it will prob be fine, if it were lowered quite a bit, or really soft drag springs they might hit when the rear squats on launch. I am pretty sure that JayC runs a 28X10.50 on his.
I am not sure but I believe the SN95 and New Edge have the same fender dimensions.
A common 275/60/15 is about a 28X10.50, which is actually only 9.7 or so actual tread width. Look at the pics of mine with 6.5bs on a 10.5" tire especially the passenger side, they come very close to the inner fender lip, but since my current lowering springs don't squat much they don't hit. To go any taller or wider especially after lowering it more I will definately move them in.

I think you will be fine with a 275/60/15 on stock springs with 6.5bs wheels, but any future mods to the suspension may cause problems if you lower it at all.
