Foam-Filled Areas
The following areas of the chassis are foam-filled for acoustic reasons:
Use foam D-000-111-A2.
Alternatively, a 2-component foam which does not absorb humidity can be used.
a -"A" Pillar
b -"B" Pillar (inside)
c - Quarter panel (outside)
d - "D" pillar
a = Holes for applying foam
A = A-pillar
B = B-pillar, inside.
C = Side piece, outside
An aluminum mesh is inserted below so that the foam does not run through.
D = D-pillar
