Are you guys using the anti-squeel lube and the backing shims? My EBC pads made a lot of noise until I took them off and put the shims and lube on.
and IMO AEM are by far the best compromise between high performance and streetablitly even though they are not a true high performance pad. They did their homework.

Oh and just FYI, stay away from EBC.... greenstuff sucks.
Anyone running Hawk pads? Tirerack has them for a decent price.
