DBA DBA53912SLVS 5000 Series T3 Slotted 2-Piece Front Brake Rotor Silver Hat

The DBA DBA53912SLVS is a front 5000 Series T3 slotted, fully assembled 2-piece performance brake rotor featuring a clear anodized silver aluminum hat. DBA's 5000 Series T3 represents the pinnacle of direct-replacement two-piece performance brake rotor technology, combining proven track-developed engineering with street-ready durability.

T3 Bi-Directional Slot Design:

This rotor features DBA's patented T3 slot pattern — 48 CNC-machined tri-directional curved slots in the friction surface. These slots channel brake dust and gases away from the pad surface, reducing pad contamination, controlling heat buildup, and preventing brake pad knockback for a quieter, more responsive feel.

Key Features:

• 2-Piece Composite Construction: High carbon cast iron friction ring paired with an aerospace-grade T6061-T6 aluminum hat, secured with National Aerospace Standards (NAS) bolts and crimp nuts
• Silver Anodized Aluminum Hat: Reduces unsprung weight, acts as a heat barrier to minimize heat transfer from the disc to the hub and wheel bearings, and allows for uniform radial disc expansion
• Kangaroo Paw Vented Design: DBA's proprietary vane configuration delivers up to 30% greater surface area and 20% improved cooling efficiency over conventional straight-vane rotors
• Thermographic Heat Paint Markings: Color-shifting heat indicators allow users to monitor peak braking temperatures and assess rotor fatigue after track or performance use
• CBN Machine-Turned Finish: Precision surface finish on high carbon alloy rings for optimal pad bedding and consistent friction performance
• ECE Approved: Meets European Community homologation standards for road use
• Fully Assembled: Ships ready to install; hats and friction rings pre-assembled with NAS hardware
