Sound proofing

[kenloen]

added weight, I know,, but considering I'm also adding a few unnecessary kgs, and the car is only used for trips out (LeMans/Spa etc) and the noise can get a bit boring after 4 hours.

Has anyone fitted any sound deadening or proofing? If so how much and where? Front Wheel wells, rear bulkhead, doors? Has it made much difference? Winters on its way and I will have time to do..
