no they don't. replace the lap seat belt mounting bolts with eye bolts and
use snap-in belts, so you don't have to sacrifice the regular seatbelt.
if you use a six point harness, you can attach the ends of the
antisubmarine strap to the seat mounting bolts. the shoulder harness
is the trickiest part. one solution i've seen is to attach to the rear
lap belt anchors, but this has the disadvantage of creating a fairly
extreme angle. note that the SCCA GCR forbids more than a 45 degree
angle from the horizontal, because moving the shoulder belt away from
the horizontal tends to cause compression of the spine in a hard impact.
and that's a very bad thing. my brother, who is an orthopedic surgeon,
a good solution from a driver protection standpoint is to bolt a
beefy bar between the b-pillars using the stock shoulder belt
anchors. this ensures that the shoulder harness doesn't compress your
spine. you need to make sure this bar is stiff, so it won't bend and
put a big bending load on the mounting bolts.
before my mustang acquired a rollcage, i located the child safety seat
tether in the rear. although the nut placed there by the factory was
too small to be used for a shoulder harness, it was welded to the
rear subframe, and i drilled a larger hole behind it for my mount. i
welded a piece of 1/4" plate to the subframe and put the mounting bolt
through it. this is probably more than you want to do to your audi,
but this is all i had to do, and it was a clean installation. after i
was done, i just had an eyebolt sticking out.
you may regard proper safety equipment as overkill, and that's certainly
your prerogative. IMHO, if you feel you need safety harnesses, you
should do the job right. i honestly don't feel that installing a proper
race harness is any more difficult than installing a schroth. i've
done several installations in several different cars.
besides, most schroth belts are 2" wide. every SFI-certified race
harness is 3" wide.

see above for my comments regarding attaching the shoulder harness to
the rear seatbelt anchors.

i'm not convinced of that, javad. i know schroth belts are very pretty
and make a nice and clean installation, but i'm not convinced they
are an improvement over stock from a safety standpoint, primarily
because of the shoulder harness issue. spinal compression is very
bad, and that's why football players aren't allowed to use their
heads to ram other players.

you will never see a schroth harness in a real race car (because it isn't
going to pass tech), and you won't see them in very many dual purpose
cars, either. mostly, i see them in riceboy cars. not that i'm calling
you a riceboy, javad. i do feel that if you are going to spend money
and effort installing a harness, you should do the job right.
we may have to agree to disagree on this one.
