Are the R1s a good alternative to Stock Rotors, Or are they an improvement. With my new Wheels/Tires I'm in need of an upgrade... My brakes were replaced about 5K ago (previous owner) Both Rotors and Pads (pads are a ceramic dust free I believe) And Rotors I'm fairly certain are OE. (I'll have to check the receipts).

Is there any "big brake" kit that's compatible with our vehicles? Are our stock calipers plenty good?

Just tryin' to be safe here
