Increase the rigidity/quiet of your A1...

[amalventano at sc.rr.com (Allyn)]

ok, some points of concern i might as well bring up.
having cut up many roccos, i've noticed that our rocker panels arent exactly
a perfect hollow tube. there are many layers of steel that run along the
center of the rockers.

so my concerns are:
1. whats a good entry point (you would have to drill somewhere)
2. how do you get the foam distributed within all areas of the rocker?
also, heres another idea, check out this pic of the front engine bay:

there are a few plugs which would allow entry points without drilling
there is also the area within the firewall:

(plug visible in this case)
theres also some decent candidates in the rear:

especially the last one. that entire beam that wraps along the wheel well is
totally hollow, as well as the beam that runs across the bottom of the
hatch, forward of the wheel wells. the part thats missing in this pic:
http://scirocco.dhs.org/vw/pics/0-allyn/project/images/030130-204021-Z10.jpg
you can see the outline of where it started just forward of the base of the
shock tower.

anyhow, this may be more creative uses of extra foam than just throwing it
into large vacant areas within the fenders/body.
