Scalloped Brake Rotor, Long Spline Rear Chevy Pattern Left

OVERVIEW

Elevate your air-cooled Volkswagen''s braking performance and visual appeal with the EMPI Scalloped Rear Brake Rotor. Engineered for enthusiasts who demand more than just standard stopping power, this rotor features a distinctive scalloped outer edge that serves two critical purposes: it significantly reduces unsprung weight for better suspension response and increases the cooling surface area to combat brake fade. When you are navigating demanding terrain or spirited canyon runs, the cross-drilled and slotted face works tirelessly to vent hot gasses and debris, ensuring that your brake pads maintain a clean, high-friction contact patch at all times. This isn''t just a replacement part; it''s a performance upgrade designed to handle the rigors of modern driving while maintaining that classic VW spirit.

Designed specifically for "long spline" rear applications, this rotor (SKU: 22-3876-7) is the definitive choice for late-model IRS (Independent Rear Suspension) setups or swing axle conversions requiring the longer spline length. One of its most powerful features is the dual-drilled bolt pattern, offering the flexibility to run either the high-end Porsche 5x130mm wheels or the widely available Chevy 5x4.75 pattern. To protect your investment and keep your wheels looking sharp, EMPI applies a robust zinc plating to the entire rotor surface. This coating acts as a sacrificial barrier against corrosion, preventing the unsightly rust buildup that typically plagues raw iron rotors. Whether you are building a show-quality street car or a rugged off-road machine, this left-side scalloped rotor provides the durability, versatility, and "wow factor" your project deserves.

PRO TIPS

1. Proper Degreasing is Mandatory

Even though these rotors are zinc-plated, they often arrive with a thin film of shipping oil or cosmoline to prevent oxidation during storage. Before you install your brake pads, you must thoroughly clean the friction surfaces with a high-quality brake cleaner. Failure to remove this residue will "glaze" your new brake pads almost instantly, leading to poor stopping performance, excessive noise, and permanent damage to the pad material. Always use a clean, lint-free rag and wipe until no dark residue appears on the cloth.

2. Torque and Safety Hardware

When installing rear rotors on a VW, the rear axle nut (36mm) requires an immense amount of torquetypically around 217 to 253 ft-lbs depending on your specific year, though many performance builders go even higher. Always use a high-quality torque wrench or a "Torque Multiplier" tool to ensure the nut is seated correctly. Never reuse an old cotter pin; always install a fresh, heavy-duty cotter pin to lock the axle nut in place. A loose rear rotor can strip the splines on your axles, leading to a complete loss of drive power and a potentially dangerous situation.

3. Directional Considerations and Pad Bedding

This is a "Left" side specific rotor. While the scalloping and drilling are designed to work in harmony with the rotation of the wheel, ensure you have the matching "Right" side rotor (22-3877-7) for the opposite side of the vehicle to maintain symmetrical braking force. Once installed, perform a proper "bedding" procedure: make several gradual stops from 30 mph to 5 mph, followed by a few firmer stops from 45 mph to 10 mph. This transfers a thin layer of pad material to the rotor, which is essential for maximizing the lifespan of the scalloped design and preventing "hot spots" on the rotor face.
