Default Tunnel Torque plate?

Is there any difference in the C5 Tunnel plate from the C6 plate? I have the old one off my 05 C6 from when I bought the Elite engineering 3/8” thick one and installed it. Would it be worth my trouble to get under the C5 and install it on her?

Absolutely.

The C6 plate is nearly as good as the 1/4" EE plate, and a hundred times better than the flimsy C5 plate.

My c5 plate made a bigger difference on my car than I thought it would. Seemed to stiffen the chassis and allow the suspension to work better.

Hmm , sounds like I need to find a C6 TP. I'm about to install an x-pipe so I'll be under there anyway.

Yes. The C6 is double the thickness of the C5 (1/8 vs 1/16). I have 2 C6 plates riveted together on my car.

Default Insulation

The elite plate is also insulated. You will be able to tell the difference from the first drive. Paid for two and was happy to do so.

Would anyone know the part number for the C6 tunnel plate?

I searched on gmpartshouse but couldn't find the part.

Why not just order an Insulated Elite Engineering plate? Better quality.

Because they're stupid expensive. I made my own out of a piece of 1/4" T6 aluminum and got some thermal shielding from Summit racing. I have about $75 into it, and 2 or 3 hours of my time. I'd stack it up against an EE plate any day.

Don't forget that the EE tunnel plate is also ceramic coated to help reflect heat. Stupid expensive? AT $205 and you get ceramic coating it is a great deal. For $289 you can get the 1/4" with thermal insulation.

plus if I was capable and had the time fabricate it in three hours then it would still cost more than buying one. If someone has the time and talent, and enjoys making their own - more power to them. Sounds like it could be a good side business? What would you sell them for?

I would like the part number so I can compare pricing.
You can get a 1/4" ceramic coated plate on the bay and add your own insulation from Summit Racing.

Just curious as to how much a stock C6 plate costs.........for that I need a part number

Wow that is fairly reasonable. It does a great job as it is, without modification?

Doesn't the torque tube have to come out to install the tunnel plate?

It sure does get wicked hot in the console if you are driving for very long.

Torque tube does not have to come out but the exhaust does or at least dropped to get it in. Wonder if you could put 2 C6 plates together?
