Stoptech 127.35019R Disc Brake Rotor - Front Right

StopTech Sport Rotor for Mercedes-Benz SL and 500E

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is a direct replacement front right rotor for factory brake systems and stock calipers. Built for Mercedes-Benz applications such as the SL500, SL320, 300SL, 500E, and 500SL, it combines a vented design with cross-drilling and slotting to support more consistent braking response in wet and dry conditions.

Part number 127.35019R is part of the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line, which focuses on OE-style fitment with performance-oriented surface machining and corrosion protection for street use.

• Direct replacement disc brake rotor for factory brake systems
• Slotted X drilled surface helps disperse heat and brake dust
• Helps reduce pad glazing and improve initial bite
• Black e-coating helps protect against corrosion
• High carbon metallurgy in most applications for quieter operation and improved crack resistance
• Vented rotor design with straight vane construction
• Coated hat finish for added durability
• Fits Mercedes-Benz SL500, SL320, 300SL, 500E, and 500SL front right applications

Detailed Fitment and Application

StopTech 127.35019R is a 300 mm outside diameter, 27.9 mm nominal thickness rotor with a 67 mm center hole and 5-lug, 112 mm bolt circle fitment. It is engineered for front right placement on 1990-1993 Mercedes-Benz 300SL, 1990-1993 Mercedes-Benz 500SL, 1992-1993 Mercedes-Benz 500E, 1994-1995 Mercedes-Benz SL500, 1994-1997 Mercedes-Benz SL320, and 1996-1998 Mercedes-Benz SL500. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Rotor Can Address

• Brake fade during repeated stops
• Excess brake dust buildup on the rotor face
• Pad glazing that reduces braking response
• Corrosion on exposed rotor surfaces
• Uneven braking feel in wet or dry driving

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and front right position before installation. Clean the hub mounting surface thoroughly and inspect pads, calipers, and brake fluid condition at the same time. For best results, follow the pad manufacturer’s bedding procedure after installation.

Quality Assurance

StopTech designs this rotor as a direct replacement for stock-caliper brake systems, with black e-coating for corrosion resistance and high carbon metallurgy used in most applications to support quieter operation and improved crack resistance.
