When it comes to one-piece brake rotors, DBA is definitely a standout in the industry. The DBA 4000 has been a favorite for autocrossers for years, and it's no mystery why. The patented kangaroo paw disk venting system is extremely efficient, and the slots do a great job of removing dust and releasing gases from the pads under extreme conditions. If you're looking for a competitive autocross rotor, definitely check out the DBA 4000. If you're looking for something a little more hardcore, DBA offers the 5000 series rotor which features a lightweight floating rotor design.
These are the same front rotors that we use on our AutoX WRX, and we haven't been disappointed.
