What is the benefit of the T3 slot design?

The T3 slot design on this rotor helps to sweep away brake dust and gases that build up between the pad and rotor surface. This ensures consistent contact and helps maintain optimal braking performance, especially under heavy use.

How does the Kangaroo Paw ventilation improve cooling?

DBA's Kangaroo Paw ventilation uses a unique pattern of diamond and teardrop pillars inside the rotor. This design significantly increases the surface area for air to flow through, leading to up to 20% better cooling efficiency compared to traditional straight vane rotors.

Does this rotor come with everything needed for installation?

This product includes one rear slotted brake rotor. Hardware such as lug nuts or brake pads are typically sold separately, so please check the product details for what is included.

About this part

Product Details

When you're looking to upgrade the braking performance on your 2018-2021 Subaru WRX, this rear slotted rotor from DBA is a solid choice. It's designed as a direct replacement for your stock rotor, making installation straightforward. This rotor is built to handle the extra heat and stress that comes with more spirited driving or track use, helping to keep your brakes working effectively when you need them most.

DBA casts these rotors from XG-150 high carbon alloyed iron, which is known for its ability to manage the increased demands of hard braking. They also feature DBA's patented Kangaroo Paw ventilation system. This design uses a series of diamond and teardrop-shaped pillars inside the rotor, which increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard straight vane designs. The T3 slot pattern on the braking surface helps to sweep away gases and dust, ensuring consistent contact between the pad and rotor for reliable stopping power.
