I have a 1999 Ram 2500 diesel 4x4 Quad Cab. The front brakes last about 30k miles... big surprise to many of you I'm sure. I'm thinking about retrofitting the factory rotors and pads, but have not seen any mention in the forums on caliper conversions. Any ideas from the folks that have blazed this trail ahead of me? I've seen that many of you say to keep away from the drilled rotor and stick with the slotted... I'll do that. But that leaves the small factory rotors. Any ideas on aftermarket items or retrofits?
