Why upgrade to ECS 2-piece rotors for your E46 M3
- Lightweight 2-piece design - aluminium hat with grey cast iron ring reduces unsprung weight by over 3 lb per rotor for improved handling, quicker acceleration and decreased stopping distances.
- Superior heat management - cross-drilled and slotted rotor faces promote rapid heat dissipation, pad deglazing and water and dust evacuation for consistent, fade-resistant braking.
- Semi-floating construction - allows radial expansion of the ring under extreme temperatures to help prevent warping and vibration for long-term reliability.
- Heat treated rings - increased stiffness and strength for improved performance under repeated heavy braking.
- High quality materials - lightweight 6061 aluminium hats, hard anodised in matte black for corrosion resistance, paired with durable grey cast iron rings.
- Precision machining - chamfered drill holes and ball end-milled slots reduce the risk of cracking found on poorly machined rotors.
- Anti-corrosion protection - non-friction surfaces, including internal vents, are painted to resist salt and road grime.
- Optimised braking surfaces - ground faces ensure parallel running and easy, even pad bedding.
