Dynomat or similar

[B 4 You]

Anyone used any types of insulation to lower road noise? After installing all-metal coilovers, road noise has become a bit obnoxious. I think using dynomat would be best, but it's way too expensive. A lot of people say they use that peel n stick stuff from Lowes or Home Depot because it's affordable. Anyone here used anything similar? I also don't want anything that produces a fowl odor...

B-Quiet from Canada is cheaper and reports like it as well as Dynamat

I used a ton of these products.... they performed very well in a comparison test (Dynamat + others).

So far I've done only backwards from under the rear seat (20 kg of material), but with very good result. Tire noise was reduced significantly.

I also used the SPL polyurethane foam (10mm) behind all trim panels. No rattles.

I've used B-quiet a couple of times and it works well and is cheaper

The stuff from Home Depot was discussed at length on the CR-Z forum when I was an owner. DON'T USE IT! On a hot day your car will smell like a roof getting re-tarred and the stuff will start to peel off. It wasn't meant to be put in cars.
