So what would you need for a 10.5 to fit? Because I've seen and heard that 295 will fit. Jimmyray has them on 17s with 17x8 and my plan is to fo 18x10.5 in rear with 6.5in bs
Based on the measurements I've taken, with a 68-70 B rear and 1/2" spring offset the 18x9.5's with 285/40/17's I want to run are going to be a just a bit more than 1/4" off the springs and will probably still need a quarter lip trim at my planned ride height.
When I mocked up the 275's on my Duster with the stock springs and rear end, they fit pretty much exactly in the wheel well. No extra anywhere, a 1/4" off the springs and right at the quarter lip. The 1/2" spring relocation should buy me enough to get the 285's, but 10mm = .4" so that's right back to pretty much no extra clearance.
Either that or you'll have to run +2" rear springs and just let the 295's hang out. But lowered and 295's with the stock wheel wells isn't going to work well. Section width on a 295 is like 11.9", stock duster wheel wells are about 12" (at the bottoms!!!). You need at least a 1/4" clearance at the springs and quarters to keep things from rubbing, and that's TIGHT. So, 11.9 + .25 + .25 = 12.4". You might get exactly that if you completely cut the quarter lip off, but then you'll have to weld the quarters and inner fenders with a bead along the edge (not fun). And even then you might not have enough because of factory body tolerances.
