I know this is a dated post...... However that being said, I installed the slotted/cross drilled Cryo Rotors from Power Stop. One of the best single upgrades I made... With my Boat and Truck I weigh in at around 24K GCW.... before I could tell I was over working the brakes for heavy stop and go traffic, now things feel as they should, no fade, brakes grab and do the job they were meant to do. ordered mine via Autoanything.com Don't recall the exact cost, a bit pricey tho as I recall, but in the end well worth it.
