Pontiac GTO Brake Rotors (2) - Front - DBA - 5000 Series - `05-`06 are direct replacement, composite 2-piece rotors designed for drivers who demand reliable braking performance and reduced rotor mass. These front rotors pair high-carbon cast-iron rings with aerospace-grade aluminum hats to improve thermal behavior without adding unnecessary weight.

Built from proven DBA 5000 Series technology, these rotors use T6061-T6 aluminum hats and National Aerospace Standards (NAS) hardware to secure the cast iron rings. The two-piece construction reduces unsprung weight, promotes uniform radial expansion of the braking surface, and limits heat transfer into the hub. Offered as complete assemblies or replacement rings, the 5000 Series is appropriate for high-performance street use, track days, club racing and rallying where improved cooling and weight savings matter.
