I run ATE Powerdisc and ceramic pads too! The discs look amazing and the lack of dust is lovely.
Full ATE PowerDisc and Ceramic pad brake overhaul done today - I’ve run these discs & pads a few times now on previous E39s inc. both my Jap import E39s and they’re superb.
Excellent bite from the off / cold and little to no dust.
I have used rotors from R1 Concepts for over 15 years, on vehicles ranging from a Dodge Caravan, Chevy Trailblazer, to multiple BMWs and have never had an issue. They’re high quality and good price and I highly recommend them.
Its been just under a week after installing R1 Concept's Geomet drilled/slotted rotors and ceramic pads, I am impressed. Extremely quiet and smooth ride but once they're hot, they get aggressive.
I bought R1 Concepts front rotors for my Lexus IS250 at 85k miles. My car sits at 143k miles 5 years later and they have been the BEST rotors i have ever used. I chose their Geomet coating, and they are so rust resistant it is ridiculous. I have zero rust on the veins or hub of my brakes at all after all this time. I have used Powerstop rotors in the past on numerous vehicles, but I find the zinc coating will always rust after a few years. The R1 Concepts geomet coating is the best in my experience.
I have R1Concepts Geo-Carbon series rotors (2nd vehicle I’ve used them on), absolutely no complaints from my Giulia. I’m rocking them with Porterfield R4-S pads and the bite in dry is very nice and feels the same in wet.
I\u2018d always use ATE, they\u2019re pretty high quality and usually what OEMs use
ATE rotors. Check the callipers, they don' t work properly.
R1 concepts are fine not the best.
The R1 concepts will be rusting in 3 months or less.
