R1 Concepts WGPN1-73038 E-Line Drilled & Slotted Silver Brake Rotor Set

The R1 Concepts WGPN1-73038 is part of R1 Concepts' E-Line series of drilled and slotted disc brake rotors, finished in a corrosion-resistant silver zinc coating. Engineered to OEM specifications, this front brake rotor set delivers improved stopping power and thermal management over standard replacement rotors.

Constructed from G3000/G11H18 grade cast iron, these rotors are formulated with multiple alloys to optimize heat dissipation and long-term durability. Each rotor features a non-directional surface finish that promotes faster, more even brake pad bed-in for quieter and smoother braking performance right out of the box.

Key Features:

• Cross-drilled holes reduce rotor surface temperature by up to 105°F and are chamfered to minimize cracking risk
• Diamond slot technology clears brake dust and road debris, preventing pad glazing and extending pad and rotor life
• G3000 cast iron construction with rust-inhibiting silver zinc finish for lasting corrosion protection
• Non-directional finish for faster pad bed-in and consistent, fade-resistant stopping power
• Mill-balanced for smooth, vibration-free rotor operation
• Direct OEM fit — no modifications required for installation

The R1 Concepts E-Line series combines performance-oriented design with OEM-quality standards, making these drilled and slotted rotors an ideal upgrade for drivers seeking improved braking performance and reliability.
