Default Tunnel plate question?

Today I had the oil changed on my 04 Coupe and while the car was up in the air I was checking out the bottom of the car and noticed mine has a tunnel plate on the car which kind of surprised me because there are various companies that sell tunnel plates and I just assumed that they didnt come with them. If I put an aftermarket one on am I really going to notice a difference ?

Your existing tunnel plate is about the same thickness as the aluminum foil my wife wraps sandwiches in. The after market tunnel plates do make a subtle difference in the way the car feels and a major difference in the amount of heat that is transferred to the interior. I've got one on my DD and I have another one being delivered for my track car. In my book, they are worth the $$.

My install page shows you the difference - mine is one of the thinner SS plates too.

Tom,

C5's and C6's come with a tunnel plate stock. The C5's is 1/16 of an inch and the C6's is 1/8 of an inch. GM beefed up the tunnel plate on the C6 because it does make a difference.

When I took off the tunnel plate on my C5, I just bent it in half with my hands and tossed it

We have fabricated a tunnel plate in 3/16 that will more than do the job for any street car. There are plates out there in 1/4 and 3/8 as well, and serve autoX and racing applications.

If you would like more information, please visit our website. We have a killer introductory price that is for CF members only.

If you have any questions, I PM'd you my cell number.

Peace
Chip

Default tunnel plate

I got a C6 plate from Gene at Fred Beans($60) and painted it with hi-temp aluminum paint to reflect the heat. Car seems stiffer and a lot cooler along the tunnel inside.

I noticed these changes also after switching.

I noticed more comfortable and predictable handling at the limit after installing my tunnel plate. The car just felt more tossable.

I also noticed that the plate tends to creak a little as the car warms up to operating temperature in the morning. The heat from the exhaust must cause some expansion, and thus a little creaking at the same time.

I addded one to my convertible. The difference in stiffness was very subtle, the difference in heat transfer (lack thereof) was dramatic!

Tom,

We have recently updated our website with more information about our Tunnel Plates and their improvement in both heat reduction and chassis stiffness.

We have sold hundreds of our Tunnel Plates, literally around the world and have received nothing but positive feedback.

Our 1/4" thick plate is the most popular on the Corvette Forum because of its added thickness AND Ceramic Coating. In addition we now have a new product, the Thermal-Overlay that really does an amazing job of further reducing the heat transfer into the console area.

Do it once, and do it right with our 1/4" thick aluminum tunnel plate.
Let me know if you have any other questions,

We won't be undersold and will match any vendor's price on the same product

Jeff about covered it...

$$$ worth mod IMHO.

I got one and..

1. The interior creeks stopped.
2. My car was so stiff, I go on 3 wheels going into the driveway.

I looked at the products available on Elite Engineering's web site and notice they have 2 thicknesses available, 1/4" & 3/8". It says the 1/4" is the most popular but does anyone run with the 3/8"?

I wonder just how much of a difference you'd notice going to the 3/8" right off?

I can't imagine much difference between the two

My suspicion is the 3/8 version is a bit of overkill...........

I am satisfied with my 1/4 "..................plate that is

When I purchased the 1/4" Thermal ABS of Aluminum for my C6 coupe, my primary goal was to get rid of the heat in the console and cup holder area. After installing the new Thermal ABS, I didn't completely get rid of the heat getting to the console, but it has reduced it enough for me to now consider using the cup holders for cold beverages (Coke or water, no beer) and take out the extra cup holder that I mounted on the passenger side of the console which returns the full range of leg room the car was intended to have for my passengers. Before I could even evaluate how well the plate was going to reduce the heat in the console, I had already noticed a difference the plate made in the amount of stiffness added to the Vette. Even just getting out of the driveway the first time I had already noticed less creaking noise from the top and more rigid feel to the tires stepping down into the street. All of the driving I have done since then also has provided a more solid feel to the car in general. So all in all, I must say that I am happy with the decision to buy the Thermal ABS of Aluminum, and am pleased with the changes it made to my Corvette.
