Tunnel Reinforcement Plate C5, & C6 Corvettes


1 in stock




For guys that love driving a Corvette the way it’s meant to be driven.

It’s not a Sunday driver unless it’s on a race track.


1997 – 2013 C5 / C6 CORVETTE Tunnel Reinforcement Plate. Reduce your interior heat and add torsional stiffness to the chassis with the TPS .25 in. aluminum tunnel reinforcement plate.

Corvette engineers understand torsional stiffness. They build a great performance car and handling is a major consideration in the design. The engineers acknowledged that a stiffer tunnel plate would improve the torsional flexing therefore improving the handling. There is a huge improvement on the C7 in this area.

This is a direct replacement for C5, 1997-2004 / C6, 2005-2013 Corvettes, including the ZO6 2006-2013, ZR1 209-2013 .25 aluminum plate
