$55 for 2 rotors, I wouldn't waste your time, a good set of blank rotors will preform better then a set of cheap dilled or slotted ones. I can almost gaurentee that if you buy those and put them on your truck you will probably not even notice a difference in braking ability and they will craked from hole to hole within a year.
IMO any money spent trying to upgrade the front factory brakes is waste of money (ie fancy rotors & pads) Put the money towards CBR, Baers, SSBC, you will get more than 10 times more return for your $.
just find a freind who gets dealer cost at autozone. (A dealer or shop) they carry the cross drilled and slotted Baer replacement brakes for the best price i have found any where.
i bought ones off ebay they were around 140 and i bought nice hawk pads...they work good better then stock noticable difference esp when stopping fast on the highway...ill try find a link
