The back spacing will vary depending on the wheel width used, example a 8 inch wide wheel with 4.0 inch back spacing will have similar clearances as a 10 inch wide wheel with 5.0 inch back spacing except the wheel lips will be 1/2 inch closer on both sides to the cars body and or suspension parts. A 8.0 inch wide wheel with 6.0 inch back spacing may rub the inner wheel wells, hope this helps Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

They've crammed a 295/60R15 drag radial in there too. Drag-oriented/hot street cars as I recall, so I've no idea about cornering (sidewall flex). Most I've run is 15x8 OEM steelies, 4.5BS, with 295/50s, with room to spare.
