Stock BMW E46 M3 and Z4M models have the power to overcome the stock one-piece rotors. CSL rotors are not 1-piece from the factory. Spirited street and track driving can result in cracked or warped rotors, causing vibrations at speed and while braking, or worse, cutting a track day short.
ECS Tuning engineered 2-Piece semi-floating rotors offer real world benefits that can be felt on both the street and track! Our 2-Piece rotors combine the advantages of weight savings and rapid heat dissipation to provide a rotor superior to stock while preventing warping and extending component life. The reduction of unsprung weight and rotational inertia allows for quicker acceleration, decreased braking distances, and more responsive handling in all driving scenarios.
When you're ready for a re-ring, ECS offers discounts on pairs of replacement rotors to the original customer or customers showing proof of ownership. Please contact the Sales Department for additional information.
Features and Benefits
- Weight Savings: Each 325x28mm 2-Piece rotor saves 3.2 pounds over stock E46 M3 rotors; the 345x28mm 2-piece rotor saves 1.1 lbs over ZCP/CSL rotors.
- Durable and Dependable: Diligent engineering, proper machining processes, and careful material selection results in a rotor set that will stand up to heavy use, road and track, without worrying about warping or cracking.
- Low Moment of Inertia: The aforementioned weight savings yields a lower moment of inertia for increased handling prowess, quicker acceleration and deceleration, and improved road feel.
- Increased Thermal Capacity: Bolting cast iron rotor rings to aluminum rotor hats in a semi-floating configuration allows for independent thermal expansion and contraction. This keeps heat away from wheel bearings and improves heat dissipation in the rotors.
- Direct Bolt-on Fitment: Diameter, thickness, bolt pattern, hat depth, and set screw chamfer and placement are identical to stock, making the upgrade a simple bolt-on affair.
