What brand did you use and how is it fitted ? (i.e. inside the wheel arch inside the boot area or outside under the wheel arches)
Approx. how much nosie reduction did you notice ? (roughly as a percentage)
I bought mine from a company selling soundproofing kits. Fit inside the car, alongthe vertical section under the rear seats, along the wheel arches.
If you are really pernickelty, remove rear seats/fold them down and get a passenger to listen and highlight noise.
Most noise if from wheels/tyres and in rwd cars the rear diff.
Also insulate front wheelarches if not done...
