This is my second purchase of these rotors. Work great, stop fast. I use these with Hawk pads. Stops on a dime.

Nice upgrade over OEM 3 years ago
5out of 5stars

I purchased a full set of these rotors as an upgrade over the stock OEM rotors. Although I haven't had them on the track yet, I have been using them on the street for about a month now. I noticed a change in the braking torque curve (as a function of pedal distanced traveled) between the two. The stock OEM rotors have fairly linear increase in torque through the pedal stroke, but the DBA4000's have a lot of initial grab, then seem to back off in increased friction until much further down the pedal stroke. I suppose this is what other folks refer to as "initial bite." A very slight tap on the brakes will scrub about 5mph off my speed almost instantly, which is taking a little getting used to but I do like it quite a bit.

Awesome Performance 4 years ago
5out of 5stars

These rotors performed very well under heavy use of a track day in Mazda Raceway Laguna Seca and in Thunderhill Raceway (5-mile configuration). My brake pads are the Hawk DTC-70 (front) and DTC-30 (rear). Braking performance with this setup is excellent. No brake fades. No brake juddering of any sort. Just excellent and consistent braking performance throughout the track day. It's a definite improvement over my previous setup with the OEM Brembo rotors (roasted in Thunderhill) with the DTC-30 pads all-around. While the braking performance was OK, however, it developed brake juddering in my second track session. It definitely hindered me from going faster and deeper in to the corner. I may have exposed the brake pads way too soon to high heat since the DTC-30 does have lower heat range. These pads were burnished prior to track day too. In contrast to my new T3 rotors with the DTC-70 pads, this setup allowed me to dive in deeper and brake later in to the corner entry with better confidence; which translates in to better lap times. Any track rat can always appreciate that! I'm definitely having such an amazing time out on the race track with this setup. I'm satisfied to have found a combination of rotors and pads to accommodate my driving style in and around the race track. I'm happy that it provides excellent and consistent braking performance I'm looking for in my 2015 STI!

They look AWESOME, the front and rear. Can't stop looking at them when parked. RSD simply the BEST no question about it.

After having these on the car for about 1500miles now Ive had a chance to get some good feedback. The wear on the rotors is very even, and required no special break in procedure. The new T-Slot design gives it a nice look, but the thing to remember is they are fully functional brake rotors with great thermal capacity!
