My pleasure. If you do nothing else, do the A Pillars(just pop them off and stuff the space with any dense cloth or foam material, it does not have to be technical, even old t-shirt material will do the job just as well(maybe better), and do the shift lever hole(with material that will stay in place and not fall down into your shift linkage...big chunks of foam etc.) The rest)B,C Pillars, sill) is all superfluous.. I had the leftover material so I tried it, but I wouldn't waste my time again.As a fellow mk4 owner this makes me happy. Treating the inside of the trim panels with some deadener and CCF helped alot on my jetta. I'm running a 1.8t and pretty stiff drivetrain mounts, so I still get a good bit of vibration. Biggest improvement for me was doing the footwells and the trunk. I'll go check out the A-pillar and see what I can do with it. I should be doing the engine bay metal sometime soon.

I have plenty of junk in my trunk so I let the "stuff" dampen rear wheel noise. If you don't, put a layer of closed-cell foam over your trunk floor, as thick as you can afford/put up with. That will also tighten up your bass(less boomy). Keep in mind the formula for subwoofer speaker size-to-trunk volume...
