This area of the M3 body shell does get a
lot of stress, and remember the M3 windshield is
bonded in place and acts as a stressed member,
where all other E30's glass snaps into the rubber.
BMW wouldn't bond it if it wasn't a "weak" area.
I've seen M3's with dimpling in this area, and
i've also seen a few with a cracked A-pillar from
being tracked or autocrossed. The crack is toward
the inside of the upper end of the A-pillar,
hidden where the door rubber seals against it.
You have to open the door to see it, i think
it's just below the upper weld. The problem is
worse on cars that don't have a 6-point or better
roll cage. On another note, my 85 Golf GTi track/
autocross car has a roof dimple coming off
the corner of the sunroof opening and it's all
due to the stresses of tracking and autocrossing
the car without a rollcage. It also happens on
the 325i models. Just cause you've never heard
of it doesn't mean it doesn't happen :-)
