RB 2pc Rotor for Mazda Miata MX-5 NC (06-15) Front

I just tested front RB rotors on NC Miata on the track Streets of Willow . Watch video at youtube DIY Racing46. Brakes are performing great under very having braking lap after lap. I even set my best time at 103F heat . Rotors were glowing red but performance was maximum at all times . I was able to brake latter and shorter than before upgrade to RB rotors , brake pads were the same DTC 60 . it was very easy to install and it looks great on the car .
