What is the benefit of the T3 slotting pattern?

The T3 slotting pattern is bi-directional and helps to sweep away brake dust and gases. This ensures consistent contact between the rotor and brake pad, leading to more reliable stopping power.

How does the Kangaroo Paw ventilation improve cooling?

The Kangaroo Paw ventilation system uses a series of diamond and teardrop patterned pillars. This design increases the rotor's surface area for cooling by up to 30% and improves overall cooling efficiency by 20% compared to traditional straight vane designs.

Product Details

DBA is known for making well-built brake components, and this T3 T-Slot rotor is a great example for your 2008-2012 BMW M3. If you're looking to upgrade your rear braking performance, this rotor is designed to handle the extra stress and heat that comes with spirited driving or track use.

It's cast from XG-150 high carbon alloyed iron, which is a strong material that can take more heat than standard cast iron. DBA also puts these rotors through a process called Thermal Stability Profiling to help them handle repeated stress. The T3 slotting pattern is a bi-directional design that helps sweep away dust and gas, keeping the brake pads making solid contact for consistent stopping power. Plus, the Kangaroo Paw ventilation system, with its unique pillars, increases the surface area for cooling by up to 30% and improves cooling efficiency by 20% over traditional straight vane designs, which is notable when you're braking hard.

This is a direct replacement rotor, meaning it fits right onto your M3 without needing any modifications. It's a solid option if you want improved braking performance and durability.
