I check this thread every once in awhile for updates; planning for future 17 inch wheel swap.
80 Malibu, stock spindles, cut factory MCSS springs so it is lowered slightly. 16x8 w/4in.bs TT2's with 255/50/16's rubbed the top of the inner fenders when the suspension compressed. No issues with the same size in back. Those are now gone but I'm planning on going with 17x8 4.5 bs in the front with 245/45/17's; and 17x9.5 5in. bs in the rear with 275/40/17's. Hoping to not have to cut/roll the wheel well lips as I want to keep the wheel opening moldings. Rearend is a GN 8.5, alum. drums and longer ARP studs, so running a thin spacer to tweak bs is doable.
