few things I would check
another mentioned the caliper slides. (highly recommended use a waterproof silicon lubricant)
I would also check your E brake cable. My car the cable seezed up on the passenger side and was draging on the rotor. This damaged alot of stuff.
I would also look at this link
Performance Parts and Accessories Catalog - Auto Parts Warehouse
I would use a slotted but not crossed drilled rotor and I would also use ceramic pads with beveled edges. ceramic is much nicer to the rotor and last longer and stops better
