I am sure others will disagree, but if you have had good service with the OEM brakes (30K is pretty descent) and no braking issues or unusual wear on the rotors, why change?...stick with the OEM ones. If you do change go to a single level of performce higher, say EBC or other aftermarket vendor...they offer slightly better braking performance at about the half the price of OEM. I would change things that do not impact the design as far as longevity, i.e. I changed out my brake hoses to HD Diamondback sheathed stainless steel braided ones to improve the "mushy feel" and flushed system with good clean brake fluid. Since I am getting good wear and excellent braking with stock calipers, pads and rotors, I will probably use new HD OEM parts to replace.
Thing is when you replace key high performance braking part that directly affects the swept area like the pads, you may find that they are harder on your stainless OEM rotors, or the pad manufacturer may want you to mate them to a higher perfomance rotor/caliper for full effect and your simple brake job cascades into a project.:newsmile093:
Doing a complete high performance design requires the system be reviewed to match and weigh the benefits, skill level, use and HD (Hundred Dollars) could turn into TD (Thousand Dollars), be careful out there... :small3d036:
