What is the main benefit of the 2-piece rotor design with aluminum hats?

The two-piece design with aluminum hats offers significant weight reduction compared to traditional one-piece rotors. The aluminum also helps to better manage heat, reducing its transfer to the hub and allowing for more consistent braking performance under strenuous conditions.

What does the T3 slotting on the rotor do?

The T3 slotting pattern is designed to help sweep away brake dust and gases that can build up between the pad and rotor surface. This helps maintain a cleaner contact patch, leading to more consistent and reliable braking performance, especially during hard stops.

Can I just replace the rotor ring if it wears out, or do I need to buy a whole new assembly?

DBA offers replacement friction rings (flat discs) for the 5000 Series rotors. This means you can reuse the aluminum hat assembly and only replace the worn friction ring, which can be a more cost-effective solution for long-term use.

About this part

Product Details

If you're looking to get the most out of your 2004-2006 Audi TT Quattro 3.2L, especially if you plan on hitting the track or pushing it hard on the street, DBA's 5000 Series T3 slotted rotors are a serious upgrade for your braking system. These aren't just standard rotors; they're a two-piece, direct replacement design that significantly improves how your brakes handle heat and reduces unsprung weight.

DBA builds these rotors using high-carbon cast-iron friction rings paired with aerospace-grade T6061-T6 aluminum hats. This combination is held together with strong NAS bolts and crimp nuts. The aluminum hats are key here – they help manage heat by reducing its transfer to the hub, and they also cut down on the rotor's overall weight. This means your brakes can perform more consistently, even under heavy use, and the reduced unsprung weight can even make a small difference in how your car handles. The T3 slotting pattern is also notable, designed to help clear out dust and gas, ensuring a more consistent grip from your brake pads.

Because these are a two-piece design, you can even replace just the friction rings down the road if needed, reusing the aluminum hats. This makes them a smart long-term investment for high-performance street driving, track days, or club racing applications where brake performance is critical.
