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.
Don\u2019t get the Powerstop drill slotted rotors. Get their regular rotors. I had them on my \u201819 2.0t and they were remarkable brakes.
I am a big fan of Centric 120-series brake rotors and either Akebono ProAct or EBC RedStuff pads.
Get the Zimmerman rotors (I got the drilled) and Akebono pads. They are awesome!!
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.
Rotors: Zimmermann blanks.
Just bought the powerstop rotors and oem break pads and they worked great. Just make sure buy the squeak shims or they make noise.
I am going to swap to ceramic pads at the next change as the semi metallic are eating the rotors.
The Brembo rotors for the i3 are the poorer quality than the OEM Zimmermann. Don't waste your money. Brake dust is not a big concern in general since it washes off easily, especially for the i3.
I went to Firestone today and I asked for a free brake inspection...They do it, they said they felt the shimmy and I gave the ok to change the rotors.
