Ford Wheels on a Coupe?

[Lines Peter]

I recently put some Blizzak snow tires on some cheap black steel wheels that
I bought at a local tire store.  My car is an '86 4kq.  I had trouble
finding 4x108 wheels, but once I started asking for the "Ford pattern" there
were lots of wheels available.  The only problem I had is that the diameter
in the center was larger than my hub.  Audis are designed to by hubcentric,
meaning that this diameter should fit snugly for proper wheel fit.  I used
the wheels for about 250 miles before making some simple aluminum spacers to
fill the gap (I have access to a machine shop).  The inner dia. of the Ford
wheel is 63mm and the outer Audi hub diameter is 57mm.  The spacer is about
15mm wide and has a slight flare on the OD that fits behind the wheel so
they won't fall out.  Most people will have strong opinions about whether
these spacers are actually necessary.  I tend to err on the safe side and it
only took me like 2 hours to make the spacers, so what the heck...  Some
people have mentioned that plastic spacers can be bought from various wheel
suppliers, but I don't trust plastic anywhere near the brakes my car.
The other thing you want to watch out for is the offset.  Offset is the side
to side spacing between the mounting surface and the centerline of the
wheel.  I suggest (as someone else did) having a wheel bolted up and check.
Make sure to try it on the front and turn the steering side to side with the
car on the ground, if possible.
Last thing, since Audis use wheel bolts instead of studs, you have to watch
out for wheel thickness.  I mean the part where the bolt goes through.  If
the wheel is alot thinner than the stock Audi wheel, then your bolts will
stick too far through the back of the hub and could cause damage.  Shorter
wheel bolts are available at the dealer (and maybe aftermarket) for VAG cars
with steel wheels.  My car didn't need shorter bolts, though.
HTH!
