The DBA 4000 Series drilled-and-slotted front rotor for 1988-1994 Chevrolet Corvette (standard suspension) is cast from XG-150 high-carbon alloyed iron and undergoes Thermal Stability Profiling to resist the heat of demanding braking. Its Kangaroo Paw ventilation uses 144 diamond and teardrop pillars to boost surface area and cooling efficiency; DBA cites up to a 30% increase in area and about 20% better cooling over straight-vane designs.
