Improve the ride and performance of your
C5 or C6 Corvette!
Since its release, our Tunnel Reinforcement Plate has been one of the hottest suspension mods for the C5 and C6 Corvette. Installed on both the C5R and C6R Race Corvettes, it has been proven over and over again to reduce the amount of torsional flex in the chassis. In addition, our ceramic coating and Thermal Overlay adds another benefit by offering heat shielding from your exhaust system.
The engineers at General Motors acknowledged the benefits of a stiffer more rigid Tunnel Reinforcement Plate and improved their original design and incorporated something similar into the new C6.
We have Taken their design one step further!
♦ Featured in both Corvette Fever and SPEED, STYLE, & SOUND magazine.
We have re-engineered the undercarriage tunnel plate on the C5 and C6 with strength and performance in mind. CAD designed and computer precision cut, our 1/4” thick (6061-T6 Aluminum) “Abs-of-Aluminum” Tunnel Reinforcement Plate is twice 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 Corvette suspension.
Below is a picture comparing the stock OEM C5 and C6 tunnel plates to our most popular 1/4” thick aluminum version (Abs-of-Aluminum)
Does your console get HOT?
Check out our "Thermal-Abs" In addition to ceramic coating, our Thermal-Abs Tunnel Plate incorporates a permanently bonded composite-fiberboard and aluminum overlay that greatly reduces the amount of heat transfer into your console area from your exhaust. The result is extraordinary.
With the combined Tunnel Plate AND Thermal-Abs, we were consistently dropping the temperatures at the central tunnel by as much as 65 degrees on a C5 and 54 degrees on a C6 when compared to the stock OEM tunnel plates.
This is the best of both worlds. All the stiffening benefits that made our Tunnel Reinforcement Plates a popular mod. and now unparalleled heat shielding with our new “Thermal-Abs”.

In addition to improved stiffening, another major advantage or our Tunnel Reinforcement plate is the heat shielding it offers. All our Tunnel Plates are coated on all sides with a specially engineered Ceramic Coating to reduce the amount of heat transfer from the exhaust into the interior console.
Upgrading your exhaust?
If you are changing or upgrading your exhaust, now is the time to install one of our Tunnel
Reinforcement Plates.
The “Abs-of-Aluminum” is a direct replacement for your stock
OEM tunnel reinforcement plate and bolts in place using the existing hardware.
Installation is very simple and instructions are included.
Other benefits include:
- Rigidly ties the right and left inner chassis rails together
-A must for Coupes and Convertibles!
- Direct, bolt-on replacement
- 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
- Sound deadening qualities
