I am getting new rotors soon and am curious if anyone has used the various rotors available from R1 Concepts. They offer std. rotors, slotted, and vented rotors. Any word on their quality and longevity? Again, these are for the Kelsey Hayes 4-piston setup....but input from the 73' and newer brakes will be helpful too.
Thanks
BE VERY CAREFUL...take a look at the Centric rotors on Rock Auto...less cost, same performance.
By itself, Slotting rotors will not enhance stopping distance.
In fact, you may suffer stress related cracks due to the type and hardening process used on the metal surfaces of these slotted rotors. Remember that brakes are heat sinks - and - as they are cycled, the durability of the metals used play large role in lifespan, stopping distance and heat disapation.
BTW most rotors are vented - factory K-H rotors were vented, as are most higher quality aftermarket brands (Centric, Raybestos,etc.).
There should be some stampings on the rotors that equate to the metal rating used in the surfaces. There are grades assigned to the variety of metals used for rotors. Check out the metalurgy grade to determine quality.
Effective brake swept area, a critical factor in fade and stopping distance, is not increased at all by adding slots.
Several members and members on Moparts tried the R1 rotors...beware.
Not only were these more expensive...there was no improvement in performance.
