Rossco-Will give it some more time and try your method (I did a hills run in Jan and it didn't help, but have machined discs again now, will give another shot).
Travis-if that doesn't work then B-Specs will go in
Simon-I tried A1RMs before and I hated them as they squealed heaps on braking(more than the pmu), maybe rotor matters. I'm not sure what's on mine, but looks like they might be the 3000s or 4000s.
Taylor-at least yours only squeal while braking, mine squeals while rolling at low speeds without brakes applied lol
