I run 295/275, but I’m not lowered. The proper coilovers may give you more clearance, though.
There’s also some reports on this forum that stock brake pads can squeak a bit. Mine do if it’s colder and the brakes don’t have heat in them yet, and I’ve noticed mild squeaking when they are warm. I’m chalking it up to “race car noises” until they need replacing and I have a plan for brake upgrades.
Car looks great. The silver accents on the wheels really set everything off, IMO!
