[s-cars] Rear caliper carrier bolt

[Tom Green]

No, that is what 034 supplies for RS2 caliper to hub bolts, so I see no
issue here.  I was just pointing out that if the bolts are ungraded  
or of
too low a grade you may be over torquing them and weakening the
connection, since some of those bolts will only stretch slightly before
failure.

IIRC, all these bolts are fully threaded.  Even though the Audi parts
that bolt the RS2 calipers in place in front are only partially  
threaded,
the Porsche bolts that bolt that same caliper in place on the 993tt car
are fully threaded.  Go figure.
