Just get slotted, drilled are prone to hot spots and cracks.
Try EBC instead. Also very good.
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.
R1 concepts slotted drilled rotors and pads along with some GoSpeed traction drop springs and alignment.
I’m happy with the EBC rotors and red pads but I can’t get them to stop squeaking.
I had this when I fitted ebc discs on my Cupra. It's went on for a few hundred miles but then went away. I think it's something to do with the grooves. My thinking was they maybe had a little lip or something that eventually smoothed off.
Just run em’ after you grind it off. For a daily I would never run drilled. Noisy, water intrusion points, eat up pads, spider crack at the drill holes from water hitting a hot rotor, and you’ll be lucky to find a shop to turn them once they warp which is going to happen.
