Im looking at buying a 1/4" thick aluminum chassis tunnel plate replace the stock one to help reduce the insane interior cabin temps.

Has anyone installed a tunnel plate, did you see reduction in interior temps, how about difference in suspension? Just out of curiousity where did you buy?

I seriously love to drive my '04 has nearly 134,000 miles on her! But the car is very well cared for!

Best bang for the buck and it will do everything you need. I just bought one! Quality is top notch WITHOUT the Corvette Tax!

Hope this helps!!!

I put a 1/4" ceramic coated plate from Elite on my 04 and it solved the heat problem.

If it's just heat you're concerned about, insulate the cabin. I did the Frost King mod and it knocked all the heat out and alot of the noise to boot...

Is that frost king stuff heavy like that dynomat stuff?

Heck no, a fraction of the weight and the cost! :cheers:

where did you buy the frost king material??

I got mine at Lowes... here's my write up on the install;

Thanks Tim. I'll drop by Lowes this weekend and pick some up and put it on the shelf for that great 3 day weekend as it sounds like you spent a lot of time installing the stuff. :thumbsup:

All day! But I did other stuff too, it's amazing how clean you can get a car's interior when you gut it! :thumbsup: I'm getting some more too, I'm doing some custom lighting work to my doors and wil insulate them with the Frost King while they are stripped down. I also have to replace my Passenger outside door handle... never ends!:willy_nilly:

I know that this is an older thread, but others may find this information valuable.

As you know, the primary contributor to heat in the vehicle comes from the exhaust tubes in the tunnel.

You can install a heat barrier (there are many types) between the floor / tunnel sides and the carpet, but this adds bulk to an already space-challenged situation, and eventually the insulation material heats up and begins to radiate heat on its own.

Insulated tunnel plates help, but they only block and do not remove the heat.

You really need some method for removing the heat mechanically.

If you take a look at where the mufflers and cat converters are located, you will see that GM has installed metal heat shields that are spaced away from the surface that they are protecting.

The air space allows for a mechanical removal of heat (as the vehicle is driven) instead of attempting to block the heat with insulation.

So, following the GM engineered model, I designed an aluminum plate to surround the exhaust (on three sides) while still leaving a 3/8" air space between the plate and the tunnel sides and the tunnel closeout panel.

Designing the plate and having it fabricated was a little tricky, but there is adequate room if you measure carefully.

I took heat measurements at the base of the tunnel before and after I installed the shield and I measured a 30 degree heat reduction under medium load conditions (driving in hilly areas) and a 20 degree heat reduction when cruising (flat roads).

If you are interested in more detailed information about the design, send me a PM.

Thanks.

P.S. I also built and installed a tunnel plate, but the goal was to improve chassis stiffness.
