Product Overview

Reduce heat. Reduce warping. Full Floating.

ECS Tuning engineered 2-Piece Tru-Float wave style rotors offer real world benefits that can be felt on both the street and track! Our direct fit?2-Piece Tru-Float rotors provide?rapid heat dissipation for a rotor superior to?stock?that prevents?warping and extends?component life, weighing in at a mere 23.4 lbs each. All-around improvement in one performance minded package.

?

FEATURES:

o? ?Weight savings: The B9 S4/S5?Front ECS 2-Piece Wave Rotors weigh only 23.4 lbs each, compared to the stock rotor at 27.8 lbs. The reduced weight of a 2 piece rotor reduces un-sprung weight and rotational inertia, improving braking and suspension performance.

o ??Corrosion resistant coated hardware

o ??Lightweight, precision machined 6061-T6 aluminum hat hard anodized with an attractive matte black finish that is both durable and corrosion resistant.

o ??The full float design allows independent radial thermal expansion and movement, reducing thermal stresses on the rotor due to uneven thermal loading under hard braking.

o ??The radial expansion allows the ring to increase in diameter without being restrained by the hat, reducing the tendency to ?cone? or distort toward the outer braking surface, improving pedal feel and pad wear characteristics.

o??Gray cast iron rings: High quality FC-30 cast iron with high a carbon content improves wear properties at elevated temperatures and has excellent thermal conductivity and vibration damping properties. ?Friction surfaces are precision ground to ensure perfectly parallel surfaces and improve pad bed in, and rotors are precision balanced for vibration free operation. Heat treating reduces the tendency for rotor cracking by reducing internal rotor stresses.

o??Durability: Non-friction ring surfaces, including internal vents, are coated with a high temp paint to resist salt and other corrosives.

o ??Slotting reduces the effects of pad glazing that often results from extremely high temperatures by continually cleaning the pad surface, resulting in more consistent stopping. Drilled holes are chamfered while slots are machined with a ball end mill - both to prevent cracking that may be present on improperly machined rotors.

o???Manufacturing quality: Manufactured exclusively for ECS Tuning in an ISO 9001 certified facility

?

IMPROVED COOLING:

o ??Heat convection (due to air flow) is considered the most important mode of heat dissipation in rotor design. The key to this is adequate air flow through the rotor.

o ??ECS 2-Piece rotors feature side-specific directionally curved vanes which pump air through the rotor at a higher velocity, leading to consistent, rapid cooling on both sides equally.?? ?

o ??The air velocity in curved vane rotors is higher than pillar-post rotors and straight vane rotors, and as such curved vane rotors have been shown to cool more effectively.

o? ?Conventional B9 S4 front rotors have a pillar-post vane design which do not pump air through the rotor as effectively and as such have inferior cooling capacity in comparison.

o???Drilled and slotted: ECS 2-Piece rotors are cross drilled to promote cross ventilation for improved cooling as well as slotted to clean brake pads and carry away water and brake dust.

?

TESTING:

o? ?ECS 2 piece rotors have been subjected to thousands of miles of hard street use and to the elements (including snow and salt) for years. They have also been subjected to scientific brutal stress testing on the track and brake dyno, performing countless high speed stops in quick succession. ?We have measured stopping distances and elevated rotor temperatures of over 1000*F for long sustained periods (to the point of rotor bluing and catching brake pads on fire), as well as subjecting rotors to careful post-test inspection for signs of irregular wear, warping, stress cracking, or any other signs of failure.

o??Our rotors have proven themselves to be robust, demonstrating excellent wear characteristics, no warping, no thermal stress cracking, no signs of hot spots and minimal pad glazing.

?

Ready for a replacement rotor set? 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.
