I have the 380mm kit. I don't have much of a review of them yet as I've only had them on a couple weeks. A few observations tho:
1. It's a big ass beautiful setup with the caliper and rotor. It catches eyes at stoplights for sure.
2. I don't notice much of a difference in braking or effort
3. When the direction of the rotor is changed (forward/reverse) there is a clicking sound from both sides. I haven't figure out if it's the pads or the rotors.
4. Under heaving braking, they are a bit loud. It's a very noticeable deep pounding sound.
