Front Brake Rotor for Shifter Go Kart Brake Systems by Righetti Ridolfi, P/N K346DF-S or K346SF-S. Ideal for front-brake equipped racing go karts, this rotor is designed to provide intense stopping power for the demands of even the most powerful racing karts! Cross-drilled design improves cooling over standard rotors.  And, rain racers take note:  cross-drilled rotors have an advantage when things get wet. Water escapes the rotor surface through the holes and allows the pad a better bite.

This brake rotor is manufactured to mate well with the Righetti Speed E2 4WP Front Brake Kit, but will fit many aftermarket or non-OEM brake systems! Point Karting has helped customers fit this rotor to many awesome projects outside of performance karts as well. 

Note: This brake rotor is directional! This means that the mounting points for the rotor are important to factor into your selection when choosing your rotor! "Right" and "Left" denote driver's right or left regarding the steering system and associated brake components. 

Overview

The K346DF-S or K346SF-S brake rotor is made of cast iron, and features a diameter of 160mm x 12.0mm thick. This model of front brake rotor is slightly lighter than the solid cast-iron rotor, but still slightly heavier than the grooved front rotors. 

Internal vented flutes within the brake rotor help dissipate heat during heavy braking, while a 3-point mounting system ensures that the rotor is held firmly in place. Additional cross-drilling through the rotor surfaces cool the pad and disc interface during use, improving durability of the rotor. This rotor is distinguished from the other front brake rotors within the Righetti line by a 'matte' finish to the rotor color when new. 

This rotor works well for Righetti Ridolfi braking systems, as well as aftermarket or non-OEM brake systems where additional front brakes on your kart are required! 

The brake caliper this pad is designed to work with is the Speed E2 Brake Caliper, model Number KB111E2-DN or KB111E2-SN.
