Whether you are just looking for affordable rotors that look much more appealing than stock or if you want to increase your BMW's braking performance, StopTech direct replacement rotors are the perfect solution! SportStop slotted, drilled, or drilled and slotted rotors from StopTech are a great first upgrade for the original brake systems of your BMW, delivering winning performance while meeting or exceeding original-equipment quality specifications. SportStop rotors improve brake system performance by wiping away the used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material more exposed to the rotor surface and promotes more consistent braking performance.

*Will not fit M3s equipped with competition package or BMW performance brake package.

What Do Drilled and Slotted Rotors Do?
- Clean and refresh the pad surface.
- Increase brake bite.
- Prevent gasses from collecting between the pad and rotor.
- Decrease unsprung weight and decrease rotational inertia.
- Improve braking ventillation and dissipate heat.

SportStop Rotor Features
- Increased initial ""bite"" response.
- Improved wet weather response.
- Reduced pad glazing.
- OE Vane Designs, including casting part line location.
- Machining designs engineered for optimal rotor integrity.
- Double-disc ground for a consistent friction surface and better pad bed-in.
- Mill-balanced for vibration-free performance.
- Black e-coating on non-friction surfaces provides lasting attractive looks.
- Enhances open wheel appearance.

StopTech Rotor Technology
With so many different rotors on the market, its quite easy to be fooled by inferior products that claim to be premium. Only StopTech rotors feature OE Specs and production processes to meet QS and ISO Quality System Standards. StopTech rotors utilize an Electrocoating finish that provides long lasting corrosion protection. This coating is exclusive to StopTech and is designed to withstand 400 hours of salt water exposure without rusting!

Inconsistencies on the friction surface area left by interior finishing processes create potential noise and vibration issues. These rough finish surfaces also prolong the pad-rotor break in period, diminishing braking power which cause longer stopping distances. SportStop rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation. Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad-rotor break in. This finish also provides quieter and smoother stops.
Rough castings left behind by substandard manufacturing processes create balance inconsistencies resulting in wheel vibration related noise. The lack of mill-to-correct balancing only exacerbates these issues. SportStop rotors feature 100% fully machined finishes, including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component. In addition, all SportStop rotors are 100% inspected for balance, and mill corrected to a tolerance of less than 20oz.-inch.
Side-split castings, while cheaper to produce, do not distribute heat effectively. The result is that they transfer more heat to one side of the rotor than the other, greatly diminishing braking power, especially in high-heat emergency situations. Original Equipment specification center-split core casting provides proper heat transfer and thermal efficiency, resulting in superior braking power and safety.
