Coated Front Brake Rotor

PowerStop AR8234SCR is a front disc brake rotor built as a direct bolt-on replacement for original equipment. It is designed for drivers who want OE-style fitment, vented construction, and corrosion protection in one replacement rotor.

Key Features

  • Part number AR8234SCR for easy identification and ordering.
  • Partially coated with silver epoxy on the hat, outer edge, and vanes to resist corrosion.
  • Vented, full cast rotor with smooth surface finish.
  • Mill balanced to support consistent operation.
  • Matches original equipment weight and vane count for fitment confidence.
  • 5-lug bolt pattern with 100 mm bolt circle diameter.

Detailed Description

This PowerStop coated hat and edge rotor is engineered for front brake service on a range of compact GM applications, including Chevrolet Cavalier, Pontiac Sunfire, Buick Skylark, Oldsmobile Achieva, Pontiac Grand Am, Chevrolet Beretta, Chevrolet Corsica, Pontiac Sunbird, and Oldsmobile Cutlass Calais. The AR8234SCR uses a rust-resistant coating on exposed areas to help preserve appearance behind alloy wheels while maintaining OE-style dimensions and performance targets. This rotor cross-references Monroe Shocks & Struts (e.g., 18060237) for the same application.

What It Helps Address

  • Corrosion on exposed rotor surfaces.
  • Brake pulsation caused by worn or damaged rotors.
  • Fitment issues from incorrect rotor dimensions.
  • Uneven braking performance from a worn front rotor.

Installation Notes and Tips

Compatible with front brake applications only. Verify outside diameter, overall height, nominal thickness, discard thickness, and bolt circle before installation. The rotor is a direct replacement style part, so it should be matched to the vehicle's original brake specifications. Fitment includes 1990-2005 Chevrolet Cavalier, Pontiac Sunfire, Buick Skylark, Oldsmobile Achieva, Pontiac Grand Am, Chevrolet Beretta, Chevrolet Corsica, Pontiac Sunbird, and Oldsmobile Cutlass Calais, front.

Quality Assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for guaranteed fitment.
