About this part

Product Details

If you're looking to replace the rear brake rotors on your 2018 or 2021 Subaru WRX, this 4000 Series HD rotor from DBA is a solid option. It's built with high-carbon alloyed iron, specifically XG-150, which is known for handling the extra stress and heat that comes with harder braking. This means you get more consistent performance, especially if you drive your WRX in a spirited way or on the track.

What really sets these rotors apart is DBA's patented Kangaroo Paw ventilation system. Instead of standard straight vanes, it uses 144 diamond and teardrop-shaped pillars. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to traditional rotors. This helps prevent brake fade during demanding use. The 4000 Series HD variant gives you all these performance benefits with a smooth, OE-style finish, making it a popular choice for drivers who want improved braking without a flashy look.
