I haven't upgraded the truck yet but I am a police officer. I have a Dodge Charger police package with the law enforcement Hemi. The brake rotors were constantly warping from the high speed driving.
The O'reilly rotors, best available, would cost me $80 a piece for the HD police rotors. They warped within two weeks at the high speeds that I drive.
I found www.R1Concepts.com
where I could buy two rotors for $120. These rotors were not only cheaper than the O'reilly rotors, but were drilled and slotted for better braking and performance. I bought the ceramic pads to go with them.
4 months later I can hit the brakes at 140 mph and the car stops on a dime and is as smooth as glass. Also, it was free shipping and arrived about 2 days later, regular delivery.
Like I said, I have not upgraded the truck as of yet because I wanted to give these a good test. But after using them for a while, as soon as the brakes need to be replaced on the truck they will get the complete upgrade. Reviews on their website from other users seem to have the same outlook that I have.
Just my opinion.
