StopTech Sport Slotted (CRYO) 01-06 BMW 330Ci Rear Left Rotor

This StopTech Sport Rotor features a deep cryogenic treatment, a one-time process that permanently improves the metal's performance and wear characteristics. It's applied to the rear left rotor for your 2001-2006 BMW 330Ci, helping to reduce residual stress and extend the service life of the brake component. You'll notice the difference in how consistently the brakes perform, especially in wet weather, thanks to the directional vane design and the slotted surface that helps evacuate gases, dust, and heat.

Beyond the cryogenic treatment, this rotor is built for reliable performance. It has a black E-coated non-friction surface for excellent corrosion protection, which holds up better than standard spray paint. The friction surface is double disc ground to ensure a consistent contact area with your brake pads, contributing to optimal performance and a longer service life. The symmetric vane and split-core casting design also help distribute heat evenly, further preventing thermal stress cracks.
