I have offered R1 products since 2009 due to personal experience and the experience of my customers for everything from 1/2, 3/4 and 1 ton gas and diesel trucks to Mustangs, Corvettes, Cadillac's and more. They offer brake parts for anything you could want, even class 8 trucks. I can also offer EBC, Baer, Brembo, Stoptec, Hawk, you name it. I can even make a larger profit on those brands, but R1 products have proven themselves time and time again on my customers' Raptors and more.
I first tested their Premier drilled and slotted rotors and Posi Quiet pads on my 2003 Duramax. I hauled heavy farm goods throughout the year with that truck and was replacing rotors and pads after every single Christmas tree season. I installed the R1 products in January of 2009, hauled with that truck for two more years before I had to quite hauling due to health problems and that same brake package was still on the truck with more than 50% of the pad left and no cracking, no warping and no extensive wear on the rotors when I sold the truck this past September 2014.
Everyone out there has their favorite brand name products, however, most personal opinions are limited to their personal experience with one brand. I have sold EBC and other brands and had customers complain about longevity and or quality. EBC is a good company with a great reputation, but I have yet to have a customer complain about anything to do with the R1Concepts products quality, performance or longevity.
