Custom Tiburon Rotors

High Carbon Rotors

These rotors are made from the finest blanks with G3000 grade castings.  The castings avoid secondary scrap that can contain stray elements of vanadium, tungsten, moly and other contaminents that cause carbides to form.  Carbides weaken the rotor and leads to warping.

Chamfered Drill Holes

Countersunk for a smooth linear transition at the edge.  This reduces stress risers which improves durability

Corrosion resistant Plating

Zinc-dichromate plating resists rust and keeps the rotors looking brand new.  Some competitors use painted rotors that will discolor, crack, and peel since rotor operating temperature routinely exceed 1000 Degrees

To drill or not to drill?

Cross-drilled rotors can improve stopping power up to 35% over stock rotors as reported in SAE Technical Paper 2006-01-0691 "The effect of Rotor Crossdrilling on Brake Performance" by two GM engineers. That's why Corvette, Porsche, Mercedes, and BMW vehicles come factory direct with drilled brake rotors. i.e. not dimpled or slotted. The fact is that the drill holes greatly improve convection heat transfer and the result is more pad bite. The report also states that "it is possible to have too many holes, in which case too much cooling air would be lost before reaching the hottest part of the rotor". These rotors are designed for optimum rotor cooling and durability with one cooling hole per vane. This also provides superior strength to avoid cracking.

STOP ROTOR WARPING!

High rotor temperature can cause heat spots to form on the rotor, and this causes pulsating brakes Cross-drilled rotors keep the brakes up a 150 degrees cooler to prevent rotor warping.
