Default Correct backspacing

So after spending a ton of time trying to find what I want to put on my TA I have found them.

So of course now I have issues figuring out the right back spacing.

I want to run 15x7 upfront and 15x10 in the rear. Looking at the wheel chart I want +35 to +40 for the x7's and +38 to +54

so backspacing in inches is 1.38 to 1.6 for front, and Rear 1.5 to 2.2

The rims I want for the front have a 4 inch backspacing, and rears are 4.5 backspacing.

My understanding these rims will stick out alittle more than 2 inches then what I want. So is it reasonable to expect that I can roll and stretch out the fenders to cover the tires. And the people that run the 15x10 rears where do they get them with the right backspacing.

The rims I am looking at are exactly these.

1. You can't fit a wheel over 4" wide in the front in a 15" diameter. If you want a wide front runner, you have to step to a 17" front.

2. Those cheap china Jegs knock off wheels don't come in the correct backspace for 1993-2002 F body cars in 15x10.

3. You need 15x3.5-15x4 with 1.5-1.75" backspace for the front.

4. You need 15x8 with 5.5" backspace or 15x10 with 7.5" backspace for the rears

5. The most common wheels that will fit over LS1 brakes in 15" are Weld Racing RTS series, Billet Specialties Street Lites, Racestar/Darkstars, and Bogarts. Again, you cannot go over 4" wide in the front with a 15" diameter without extensive brake modification.
