Star Brake Rotors are made of laser cut, and parallel double disc ground 410 Stainless Steel. Our Front Full Floating Rotors have a center composed of aerospace 6061 Aluminum alloy (magnesium/silicon/titanium), with a T6 heat temper grade. Again that’s all the technical stuff, what this means on the street/track is; Since they are laser cut, and parallel double disc ground, they have a stress free, perfectly flat surface, meaning a large contact patch from your pads to rotors. The higher the contact patch, the better the braking! The 410 Stainless steel, which they consist of, has a melting point of just less than 2800 degrees. It has good impact strength, and corrosion/scaling resistance up to 1200 degrees, so you can put them through the abuse. The 6061 Aluminum that makes up the center has a T6 temper grade, meaning that it’s been heat treated; it also means the centers have a melting point of just less than 1100 degrees!
