  1/4" Aluminum Tunnel Plate and "Thermal-Abs of Aluminum"
 At a full 1/4" thick 6061-T6 aluminum, this plate is twice as thick as
your stock OEM Tunnel Plate;  Coated on all sides with a specially engineered ceramic coated and then bonded to a composite-fiberglass thermal barrier.  

This is the best choice and BEST SELLER to offer both chassis stiffening and superior heat shielding to reduce the amount of heat transfer from the exhaust.

Since its release, the redesigned 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 adds another benefit by offering some 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

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)

    Tunnel plate

    Makes factory item look worthless.

    Upgrade, just temper your expectations.

    Posted by Matthew Davis on 25th Sep 2020

    Install was straightforward, well machined piece. Did a test run with stock plate, temp read on stripped center console (bare metal in cockpit over torque tube) was 123F. Installed plate, did a longer run, temp read 116F. So there is SOME temp reduction, just not enough to prevent me from doing additional exhaust shielding and installing something in the cockpit to prevent me from burning my elbow. Will test again during next track day, with stock plate I burned my elbow, will see if bearable with this plate.

    Super product!

    The 1/4" ceramic coated insulated torque tube plate was an easy install for my mechanic. Drove 100 miles home on an interstate at speed and noted much decreased heat in the center console. Handing seemed to be indicate a stiffer ride, but time will tell. Overall, I am very pleased with the purchase.

    Super nice product!

    I purchased the tunnel plate to knock down some of the heat that swaps in to the car. I haven’t installed it yet as I’m waiting on some other insulation and a cat less x pipe for my C6Z before I tackle the project. I can say it’s a quality piece and looks like it will meet all of my needs!

    Top notch!

    Posted by Mark Hoffman on 15th Nov 2019

    Have not installed yet, but out of the box - WOW! Very impressed with the quality and the speed of delivery was unbelievable. If you’ve ever ordered anything on line, be prepared to play the waiting game. Not with these guys!

    Exceeded Expectations

    Posted by Eric on 25th Sep 2019

    I received and installed the tunnel plate on my C5 Z06 and I am impressed with both product quality as well as radiant heat reduction. I think it has also helped with structural integrity however that is a little more difficult to prove.

    Easy install when doing exhaust. Definitely makes center tunnel interior much cooler. No heat on legs. Now to cool foot area.

    Great upgrade for a C6

    Posted by Tony on 30th Apr 2015

    Strengthens the car and reduces the heat in the console tremendously. It used to be very hot and now after an hour drive it is moderately warm. Installed with a set of headers which normally would increase the heat. I bought the one with the Thermal-Abs. Excellent investment.
