Since it has been several months since I have been under my '04 Vert and I just do not remember.....is there a factory tunnel plate there or were these only on Z06's?
If not one there, are there provisions for one? What would I need to get to add a tunnel plate?
Okay...good to know...thank you.
Sooo....is the OEM plate plastic or something so these aftermarket 1/4" aluminum plates are supposed to increase chassis stiffness...???
OEM plate is very thin. Just a stamped piece metal. The aftermarket plates are much thicker. Supposed to increase stiffness but I don't know the numbers.
There are all sorts of aftermarket plates available. Most thicker than the OEM plate and some with an insulation coating that helps minimize the heat of the exhaust from rising up into the tunnel and causing the interior of the car to get hot. If my car had headers I would definitely consider an insulated plate. YMMV
I installed the Thermal Abs Insulated plate just for the purpose of the heat and I'm not running headers but between that and insulating the interior it made a world of difference. The tunnel doesn't get no where nearly as hot as it used to.
