15x7 torque thrust/stock 66 289

American racing has the 15x7 torque thrust with a 3.75 backspacing. Will this allow rear fender clearance without rolling the rear fender? From earlier posts I read that 4.25 backspace is optimal, but in that style of wheel, 3.75 is all you can get in 7" wide. Thanks.
 
Should be fine - depending on what tire you plan on putting on them. I've got the 15x7 AR Torque Thrust wheels with 225-60-15 tires and they fit fine.

I don't know the back-spacing of my wheels, but if you say they only come in 3.75, then that must be what I have.
