I went with R1Concepts rotors which are supposed to be pretty good in quality. I haven't done nearly enough heavy braking to get the rotors to warp in the three months I've had them.

Its close to your ear and sometimes you can hear it.
The control arm I'm a bit skeptical on, to be honest. The shop that did my wheels said it would need to be done "sometime soon," but it hasn't been mentioned by the dealer when I brought my car for recall service and they do their full inspection (they look for anything they can try to convince you to get service for). I've noticed zero issues with stability, handling is as good as ever, no pulling to one side, etc.

Or ounces.
I'll have the shop rebalance the wheels and search harder to find somewhere I can bed the brakes. Thanks!
