The go-to big-brake upgrade for F-Series BMWs running 370 mm front discs from factory.
If you drive a performance BMW and regularly find yourself pushing on B-roads, doing fast-road miles, or hitting the occasional track day, you already know the stock brakes can only go so far. This DBA 4000 Series T3 + XP Pad Combo is designed for drivers who want a stronger bite, more consistent braking, and far better heat control during sustained spirited driving.
The 370 mm DBA 4000 Series T3 discs feature advanced ventilation, refined T3 slotting, and Thermal Stability Profiling for exceptional performance and durability, even under heavy braking loads. Paired with DBA’s XP (Xtreme Performance) pads, this kit offers a high-friction semi-metallic/carbon fibre compound that holds strong up to 550°C without fade.
The discs and pads are engineered to work together, giving you predictable stopping power, better pedal feel, and a serious upgrade over standard F-Series braking — all with direct fitment and no modifications needed.
