Centerline Rev wheels 8" wide with 4" backspacing. 275/60 BFG Drag Radials. A lot depends on your ride height, when you start lowering the car like JEVANS or mine, clearances get a lot tighter. Also, brands of tires are not always the same size despite having the same size rating. In other words a BFG 275/60 isn't exactly the same size as say a M/T 275/60. I find the BFG's are just a tad narrower. You also have to deal with the fact that the rears on these cars are never perfectly centered with the body.
With my GN I had to trim the wheelwheel trim slightly. Still getting an occasional scrape sound depending on what angle I take a driveway at. Might need to nibble away a bit more. On my driver's side I am getting some rubbing on that damn part of the frame towards the rear of the wheelwell. Might have my welder do a little surgery on that someday.
Most of the wheel manufacturers only offer wheels with 1/2" backspacing. Example, Welds 8" wheels would have 3 1/2" backspacing which would stick the tires out 1/2" more than the wheels I got. That's the main reason I went with the Centerlines and it is nice going to a show pretty much knowing you won't see another set of wheels like these.
Don't forget, if changing tire height you will need to change the speedo gear to keep things accurate.
