DETAILS

DBA's mid-series enhanced performance rotor features Thermal Stability Profiling for improved heat handling. Thermo-Graphic paint markings on the rotor allot for effective heat monitoring, when the painted lines change color you can see the temperature that the rotors have reached allowing you to accurately match the proper brake pad compound. With a precise array of tri-symmetrical ‘T’ slots, the patented T3 design brings major performance and practical advantages to the motoring enthusiast. These key features make this a great rotor for street use, and the weekend warrior who demands the most out of their car on and off the track.

Details:

  • T3 Slot 48 precision CNC machined slots that are tri-symmetrical curve slots
  • Slots create out-gassing exit points for brake pad friction gasses to escape
  • Increased surface area resulting in greater heat dissipation
  • Kangaroo Paw 144 diamond and teardrop pillar ventilation system
  • XH150 High carbon alloyed iron materials
  • Thermographic Temperature Monitoring system
  • Paint protection on non-friction areas
Note: This is for an individual rotor, please enter "2" in the quantity box to order a set.

Excellent Performance

The DBA 4000 Series Slotted Front Rotors for the 2018-2021 STI are a very nice upgrade for my 2021 STi.

Key Features and Benefits:

T3 Slot Design: The patented T3 slot design with its tri-symmetrical slots is a key feature. These slots help to:
Reduce vibration and noise
Improve brake pad bite
Provide better heat dissipation
Allow for out-gassing of brake pad friction gasses
Improved Braking Performance: Many users report noticeable improvements in braking power and consistency, both for street driving and more demanding track use.
Durability: These rotors are known for their quality and longevity, with some users reporting years of use.
Aesthetics: The slotted design gives a more aggressive and performance-oriented look to the car.
Potential Drawbacks:

Cost: DBA 4000 series rotors are generally more expensive than OEM replacements but are worth it.
Noise: While the T3 slots are designed to minimize noise but I perceive a slight increase in brake noise compared to smooth rotors.
Overall:

The DBA 4000 Series Slotted Front Rotors are a well-regarded upgrade for the 2018-2021 STI. They offer a good balance of performance, durability, and aesthetics. While they are more expensive than stock rotors, I consider them a worthwhile investment for improved braking performance, especially when I drive aggressively or participate in track events.

Hi Mauricio,

Thank you for your detailed feedback! Those T3 slots really make a difference in performance. Glad to hear you are loving the upgrade!

These work so well. Great replacement for brembos. In my opinion they’re better than brembos! They’re so good I accidentally made my girlfriend smack the dash so hard after saying “let’s see how good these DBA’s are”
