Rocket Racing Attack 18x10 6" bs all around w/ 275-35 and 295-35 NT05 tires. So far fit looks good. Don't see any issues in the front - should be OK w/o a spacer. In the rear I have 3/8" clearance to the seat-belt hump and 1/2" to the spring. Should work as is - but I have 1/4" spacers I may use to give a little more inside clearance. Car isn't ultra low so doesn't seen to be much of an issue on the fender side - I could go out .5" easy. Rear is 4th gen, so it's .75" wider than a factory 2nd gen rear. When I build a 9" I will go with this same width as it works a bit better for these wheels vs. the 2nd gen width. These wheels have more caliper clearance with 6" bs vs. 5" and they don't offer them in 5.5" for the 10" width.
