Below a close up, 8 mm thick sandwich construction.

All the parts except the floor mats have a self adhesive side and a grey rubber side. Just pull back the protecting foil and stick the parts in place.

Above the the Noisekiller Self-Adhesive Barrier Mat, it's a heavy but very thin and mouldable material. These small mats are fitted to the inside of the door skin. The small piece is enough to make the door sound much more solid and take out the drumming noise.

Fitting the kit:

The Noisekiller kit is replacing my previous attempt to get rid of the noise. My home made kit was made out of water sucking foam and cheap carpeting. So first of all I had to remove the old home made noise killing material. The basic foam had disintegrated a lot during the 7 years it has been fitted. Dismantling and fitting back the hand throttle kit made is a little bit more complicated. Also if have fitted a round or flat series heater you will have to dismantle is or work around.

A cheap but not very successful way of killing the noise but very effective for collecting water.

I decided not to cover up any of the gearbox tunnel screws in case I have to open up the floor pans and remove the seat box sometime in future.
