R1 Concepts 830-40121R Drilled Slotted Brake Rotor GeoPerformance Series

The R1 Concepts 830-40121R is a high-performance drilled and slotted brake rotor from the GeoPerformance series, designed to deliver superior stopping power and enhanced thermal management. This rotor features R1 Concepts' advanced dual-pattern design combining cross-drilled holes and diamond-cut slots for maximum braking efficiency.

Key Features:

• Cross-drilled and diamond-slotted design for optimal heat dissipation and debris removal
• Manufactured from high-grade G3000 cast iron for exceptional strength and durability
• Precision-drilled holes are chamfered and countersunk to prevent cracking and promote smooth pad bedding
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• Special corrosion-resistant coating provides superior rust protection and improved appearance
• Built to OEM specifications for direct fit installation with no modifications required
• Non-directional finish promotes faster, more even brake pad bed-in
• Diamond-tipped slot ends serve as wear indicators for rotor replacement

The drilled pattern reduces rotor operating temperatures by up to 105°F, while the slotted design extends both pad and rotor life. Ideal for daily driving, light performance applications, towing, and street performance use. The GeoPerformance series delivers professional-grade braking performance with enhanced corrosion resistance for long-lasting reliability.
