How to Reduce Road Noise in a C6 The C6 Corvette is a powerful and light sports
car produced by GM autel
md802. One of the ways the Corvette is kept light is through sparing use of
sound dampers and sound insulation. In order to reduce road noise in your
Corvette,you can install additional sound insulation inside the cabin and rear
hatch,along with insulation on the fender liners. Tire selection also makes a
dramatic difference in sound levels autel

reduce road noise. Things You'll Need Socket set with ratchet Sound insulation

the door panels by removing the two bolts that are below the door handle. The
bolts are hidden by a small panel that you can remove with a small flat head
screwdriver. The panel is held in place with clips that you simply pull out.
Disconnect the electrical connection for the power window,then set the panel
aside. The passenger side door panel removal requires removal of the plastic
panel piece to the right of the power lock switch,then removal of the bolt
underneath,followed by removal of the bolt at the bottom of the handrail. 2.
Install sound insulation sheets on the door skins,cutting them to mimic the
shape of the door. Put an extra layer around the lip of the speaker hole to help
control vibrations. There are several aftermarket sound insulation brands
available,and some companies will even custom cut an insulation kit for your
specific Corvette. 3. Remove the carpeting in the rear hatch and lay down sound
insulation. Since the Corvette is a hatchback,you get more cabin noise because
there is no trunk partition as in a traditional coupe. In addition to laying
down sound insulation,specialized companies like Blockit and Lloyd's make simple
drop-in sound insulation mats for the hatch area,along with mats that slide
under the carpet behind the seating. 4. Remove the plastic fender liners and
coat the both sides with rubberized undercoating spray. The rubber coating will
cut down on road noise,and the noise from road debris being kicked up by the
tires. The fenders are held in place with eight plastic screws -- one on top,two
on the side,one on the fender lip and one underneath the rocker panel -- along
with a single bolt near the brake duct. 5. Replace the stock Goodyear tires. The
stock tires on the C6 are designed for maximum traction,which results in a loud
and harsh ride. There are several quality high-performance tires which offer
similar dry traction,better wet traction and a quieter ride.
