Tunnel Reinforcement Plate

Improve the ride and performance of your Corvette!

Since its release, the redesigned Tunnel Reinforcement Plate has been one of the hottest suspension mods for the Corvette. It has been proven over and over again to reduce the amount of torsional flex in the chassis. The engineers at General Motors acknowledged the benefits of a stiffer more rigid tunnel plate and improved their original design and incorporated something similar into the new C6.

We have taken their design one step further!

We have re-engineered the undercarriage tunnel plate on the C6 with strength and performance in mind. CAD designed and computer precision cut 6061-T6 Aluminum, our 1/4” thick “Abs-of-Aluminum” Tunnel Reinforcement Plate is two times the thickness of the stock OEM plate. The benefits of this added thickness is a much more rigid and stiffer tunnel plate. Therefore reducing the amount of flex in the chassis and improving the overall functionality of the C6 suspension.

Below is a picture comparing the stock OEM C6 tunnel plate to our 1/4” thick version.

On the Right: Elite Engineering's Redesigned Plate!

If you feel our 1/4" thick plate is not enough, we also offer a 3/8" thick version. In addition to improved stiffening, our plate is also offered with a Ceramic Coating to reduce the amount of heat transfer from the exhaust into the interior console. Although the C6 does not experience the same amount of heat transfer as the C5, some heat is still present.


Other benefits include:

  • Rigidly ties the right and left inner chassis rails together
  • A must for Coupes and Convertibles!
  • Direct, bolt in place replacement
  • Machined C6 insignia
  • Greater sense of control behind the wheel when cornering
  • Reduced squeaks, creaks and noises while driving
  • Significantly decreases the heat transferred to the interior console
