FEATURES OF KINETIC  DRILLED & SLOTTED ROTORS FOR BMW E38

• Castings are made using SAEJ431 metallurgy from ISO9000 registered foundries
• Large drill holes reduce stress risers in your BMW E38
• Holes are engineered for optimum cooling to prevent rotor warping
• Zinc-dichromate plating resists rust for years and it provides much better protection than painted rotors.
• Precision machined using state of the art CNC machine for perfect fit and balance
• Custom chambered holes to prevent rotor cracking

THE SCIENCE BEHIND FASTER STOPS FOR YOUR BMW E38!
Cheapeuroparts.com's BMW E38 Cross-drilled rotors can improve stopping power up to 35% over stock rotors as reported in SAE Technical Paper 2006-01-0691 "The effect of Rotor Crossdrilling on Brake Performance" by two GM engineers.  The fact is that the drill holes greatly improve convection heat transfer and the result is more pad bite. The report also states that "it is possible to have too many holes, in which case too much cooling air would be lost before reaching the hottest part of the rotor". Kinetic rotors are designed for optimum rotor cooling and durability with one cooling hole per vane in your BMW E38 7-Series. This also provides superior strength to avoid cracking.

STOP ROTOR WARPING!
High rotor temperature can cause heat spots to form on the rotor, and this causes pulsating brakes.  cheapeuroparts.com's BMW E38 Cross-drilled rotors keep the brakes up to 150 degrees cooler to prevent rotor warping.
