StopTech 121.42094 Premium Brake Rotor

The StopTech 121.42094 Premium Brake Rotor is a direct replacement disc brake rotor designed to deliver OE quality with enhanced performance features. This one-piece rotor is manufactured from high-quality cast iron with superior metallurgy to ensure reliable stopping power and extended service life.

Key Features:

• Direct replacement for factory brake systems - fits stock calipers
• Black E-coating finish provides long-lasting corrosion protection in critical areas
• Double disc ground friction surfaces ensure parallelism and eliminate run-out
• Fully machined hat for improved balance and professional appearance
• Mill-balanced to reduce vibration and noise
• Manufactured under QS and ISO quality system standards

StopTech Premium rotors feature an advanced electrocoating process designed to withstand 400 hours of salt water exposure without rusting, making them ideal for all-weather driving conditions. The double disc grinding process creates a smooth, non-directional friction surface that promotes effective pad break-in and delivers quieter, smoother stops compared to standard replacement rotors.
