BMW Drilled & Slotted Brake Rotors

Cross-drilled rotors are a quick and simple way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder when itaEURtms time to stop NOW! Tests have shown (and drivers can feel) the immediate improvement. The holes also provide better cooling under hard use. Pad wear may be accelerated slightly (depending on driving technique), so only high quality brake pads should be considered.

Slotted rotors provide much of the increased pad bite that cross-drilled rotors do, but can handle the heat of more aggressive use. The slots act as a wiper, cleaning the pad face as they go by to reduce pad glazing, keeping the pads fresh for optimal performance. If taking the car often to track days or where very spirited driving is the norm, slotted rotors are the smart choice.

Cross-drilled and slotted rotors combine the best of both. Fewer holes mean longer pad life with little penalty in the way of initial pad bite. These are popular, aggressive-looking patterns that look great behind custom wheels.

Every SportStopA(r) rotor is finished with black e-coating on both sides of the hat, inside the the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these area can lead to installed lateral run out issues.

BMW made two rotor types in the stock 335/435 sizes: blank and a slotted/dimpled style. Both are in the stock 340x30mm size. This Stoptech performance rotor is a drilled and slotted version of the stock rotor. It's a direct replacement for the stock rotor on the 2012+ F30 335i/335xi and F32 435i/435xi. These rotors will also fit the 2012+ 328i M Sport brake upgrade. These are an ideal replacement rotor over the pricey factory rotors.

Cross-drilled and slotted rotors combine the best attributes of both styles for a sporty and functional braking upgrade. The drilled holes improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder when it's time to stop NOW! The holes also provide better cooling under hard use. Slotted rotors provide much of the increased pad bite that cross-drilled rotors do, but can handle the heat of more aggressive use. The slots act as a wiper, cleaning the pad face as they go by to reduce pad glazing, keeping the pads fresh for optimal performance. Every Stoptech rotor is coated on the internal vaning and both sides of the center hat with an electrostatic black coating. This coating prevents unsightly rust from forming on the visible sections of the disc.

Price is for the pair of front rotors.

ECS V4 Brake Rotors are Electrostatic Coated to prevent rust more effectively than the typical phosphate finishes used by other manufacturers. Oftentimes these phosphate coatings are only preventative during shipping and storage, resulting in immediate visible corrosion once exposed to heat and moisture on your vehicle. ECS's Electrostatic Coating is tested to endure 400 hours of salt spray exposure without rusting to save you the headache that comes from both the unappealing aesthetic of rusty rotors and associated run out issues. ECS V4 Rotors have a fully machined finish to promote superior rotor balance and to give your car an attractive rotor that peeks out from behind your beloved wheels. ECS's V4 Rotors are designed to have a double disc ground, taper free finish - this prevents run out through guaranteed parallelism and accurate disc thickness variation (DTV). This process prevents the finish from being directional, facilitating a more effective pad and rotor break-in period, along with smooth, silent stopping power for the life of the rotors. ECS V4 Cross Drilled and Slotted rotors will give your vehicle track appeal, complimenting the rest of your wheel and suspension setup. Slotted rotors are designed to prevent brake dust and debris buildup from inhibiting performance, giving you more consistent brake feel. Cross drilled rotors keep your braking system cooler, thus reducing brake fade. Combining both cross-drilled and slotted rotor types gives you more reliable performance whether you're in stop-and-go traffic or driving in wet road conditions. ECS Tuning carefully controls the cooling rate during the manufacturing process to ensure that the drilled and slotted rotors meet or exceed tensile strength requirements. Additionally, V4 Cross Drilled and Slotted Rotors are designed independently for the left and right side of your vehicle, ensuring that the drilled holes do not touch any cooling vanes. Features: V4 Cross Drilled and Slotted Rotors Electrostatic Rust-Inhibiting Coating Fully Machined Finish Surface Roughness production standard: RMS = 64.3, Ra = 1.6 micrometers Individually inspected for balance, and mill corrected Symmetric, OE Style Vane Casting Engineered to meet all OE specs, along with QS and ISO Quality System Standards

Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. Cross-drilling a rotor is a way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder.

By combining both Cross-drilling and slotting, these rotors combine the best of both worlds. Fewer holes mean longer pad life with little penalty in the way of initial pad bite.

These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.

These front brake discs / brake rotors fit:
2007-2010 E90 335i, 335Xi sedan
2007-2010 E92 335i, 335Xi coupe
2007-2010 E93 335i, 335Xi convertible
