StopTech 320.66057F GCX Plain Front Brake Rotor with GEOMET Coating

The StopTech 320.66057F is a premium one-piece front brake rotor featuring advanced GEOMET Elemental Protection coating for superior corrosion resistance and extended service life. Engineered to restore OE performance while offering maximum durability, this plain rotor provides reliable stopping power for daily driving applications.

Advanced Coating Technology:

• Full GEOMET Elemental Protection coating on all non-mating surfaces inhibits rust formation and extends rotor life
• Partial coating on friction surfaces results in 10 percent faster pad bed-in while eliminating corrosion rings
• Road-ready from the box with no additional preparation needed

Precision Engineering:

• Double disc ground braking surface ensures parallelism and eliminates runout
• Near-perfect disc thickness variation (DTV) for smooth, consistent braking
• Non-directional finish on friction surface promotes effective pad-rotor break-in
• OE-style internal vane designs ensure proper cooling and original performance
• Fully machined non-friction surfaces restore factory appearance

StopTech GCX rotors offer class-leading application coverage and are manufactured to meet or exceed factory specifications. The premium GEOMET coating provides long-lasting protection while promoting efficient rotor cooling, making this an ideal direct replacement for worn factory rotors.
