Each rotor is double-disc ground and machine-mill balanced for optimal high-performance operation. Our rotors are manufactured from premium-quality cast iron that meets or exceeds G3500/ISO9002,QS9000/VDA 6.1 specifications. Every rotor is inspected using the strictest quality control standards and checked for compliance with factory dimensional specifications. Still drilled rotors can be high maintains and warp easily under heavy use as owner of new Vetts have found out.Premium Cross-Drilled & Slotted Rotor Specifications Machined And Finished In Our USA FacilityĪll Cross-Drilled and Slotted Brake Rotors are precision-machined and finished in our U.S. Now the mass missing from the drilled holes is design into the equation and can be compensated for. This is a different case if a brake is design from scratch to use drilled rotors such as the new Vetts.

Your are in a sense spending good money on worn out rotors. And as has been mentioned are known to crack. The problem is if you remove metal in a different way as in drilling holes, how do you know if too much mass is removed? You can now longer measure the thickness, this doesn't work any more.ĭrilled shock rotor warp much easer, should never be machined and cause pads to wear out faster. This is why there is a minim thickness specification on a rotor. Now the rotor no longer has the properly designed mass to properly dispense the heat generated by braking. This is exactly what happens as a rotor wears or has been machined in service. If you take a stock rotor for any specific vehicle and drill it and slot it what have you done? You have removed metal mass from the disc. I am assuming a rotor and caliper combination design to work together.

Nowukno, you appear to have bigger brakes.
