I will send you a pm with a quote shortly. The number one thing to remember about the pricing. I do not promote R1Concepts because they are the cheapest options out there. I promote their rotors and the PosiQuiet ceramic pads because I have tested them in much harsher conditions than you will probably ever see in your Suburban. I originally installed their Premium drilled and slotted rotors and Posiquiet ceramic pads in January of 2009, ran them all year, (hauling farm goods throughout the year) and during the Christmas season that year ran about 7K miles under average loads with a total gross combined vehicle weight of 35K lbs through the mountains of Virginia, conditions that normally left me with metal to metal with absolutely nothing left of the pads themselves and the rotors so damaged they weren't salvageable. Not only did they survive, I ran one more year hauling and one more Christmas tree season before I had to quit hauling due to increased physical issues. Those rotors and pads are still on the truck sitting in the driveway today with over 50% of the pads still left on them. As for the rotors? No warping, no cracking, no pitting.....nothing. IMHO, although not the absolute cheapest out there, you will not find a better value on rotors and pads. Period. I am currently running their drilled and slotted rotors on everything I own, right down to my son's daily driver 2000 Suzuki Esteem. There will never be another combo put on anything I own.
The R1 website HAS been having issues this week, allow me time to make a phone call and I will PM you with the details.
(((Side note, NO, I was NOT running legal with the weights of the Christmas trees and YES, I greatly surpassed what the truck was built for, but the truck never whimpered and after installing those brake parts I haven't had to buy more. Before that I was replacing stock style rotors with ceramic pads every single season without fail)))
