Brake Cooling Ducts

The 2006 Corvette Z06 uses a duct on each side to carry cooling air to the front brakes. On early vehicles, the duct carried air rearward to an opening in the wheel liner 
(fig. 15).

After VIN 1G1YY26EX65100198, a longer duct is used (fig. 16). It passes through the wheel liner and dumps air directly on the brake assembly.

One wheel liner is used with the short duct, and a different liner is used with the long duct. There are no service parts available for the short duct setup.

Regardless of which type of duct the vehicle originally had, if a replacement is necessary, the long duct and corresponding wheel liner must be used.

Here are the combinations of part numbers that must be ordered for the long duct and wheel liner.

TIP: Some vehicles built before the VIN break may not have the duct fastener mounting holes in the frame. When necessary, these holes will have to be drilled and tapped for the M6 fastener (fig. 17).
