ECS Tuning 2-Piece Lightweight Front Brake Rotors - Pair (338x26)

Lightweight two piece front brake discs, set of 2, 338 x 26 mm

Looking for a serious stopping power upgrade for your BMW without the penalty of extra mass? This pair of high performance two piece front brake discs delivers sharper response, cooler running and confidence on fast road and track day use. Engineered with an alloy centre and high carbon iron rings, these discs shed unsprung weight and rotational mass, improve pedal feel and help your tyres work harder under braking.

We have fitted these discs to customer cars and our own builds, and the feedback is exactly what enthusiasts want to hear, crisper bite, stronger repeatable stops and less fade when worked hard. If you want a front brake disc upgrade that looks the part and performs, this is it.

Why upgrade to these performance front discs

• Significant weight saving, approx 4.7 lb per side, around 2.1 kg, for faster turn in and better suspension control
• High carbon grey iron friction rings for outstanding thermal stability and consistent friction at high temperatures
• Precision machined grooves and cross drilled pattern to de-gas pads, clear water and dust, and maintain a clean contact surface
• Curved internal vanes for directional airflow and faster heat evacuation than straight vane OE discs
• Heat treated rings to reduce internal stress and resist cracking under repeated heat cycles
• 6061 aluminium centre hats, hard anodised in matte black, strong, light and corrosion resistant
• Semi floating two piece layout allows the ring to expand radially under heat which helps resist distortion
• Non friction areas, including vents, finished to fight road salt and grime for long lasting good looks
• Ground braking faces for quick bedding in and parallelism

Real world gains you can feel

• Reduced unsprung weight improves ride quality and grip over rough roads
• Lower rotational inertia helps your car accelerate and decelerate more efficiently
• Shorter, more consistent stopping distances during spirited driving and on circuit
