My mistake. I just assumed you still had the small pattern. With 5 on 4.5, you probably have a thousand choices.
But you are still mixing up backspace and offset (post #28) But 4"backspace, or -6mm offset (if that offset moves most of the wheel toward the inside) should work good on a 15x7.
And I'm a huge fan of torque thrusts too. I have a pair of 15x7 tt2's on my 62 on the front. I can get you the backspace measurements if you want. (The one piece have a fixed bs, the two piece can be custom).
