       Stock offset is about 35 to 37 mm, which is a bunch.  I am running 3/4 
inch spacers on all four corners of my 84 race car, which changes the 
effective offset to about 16 mm.  I want more offset, but the Campagnolo 
Daytona style wheels that meet the SCCA class requirements of a 6 x 14 wheel 
have too thick a center.  If the wheel centers were thinner, I would run inch 
spacers.
       Of course, I have longer, larger studs to fit the spacers.

       I think the 7 x 15 Ford Mustang GT and LX wheels from the mid 1980's 
have about exactly the right offset.  Since the rims are wider, they fit out 
closer to the fenders, even though the offset is about 25 mm, as I recall.  
You do have to cut the back side of the Mustang wheels slightly to clear the 
stub end of the Alfa rear axle.  Plus they are cheap.
       I am running 225 50 25 tires on Mustang wheels on my lowered 82 
spider.  I would suggest not going that large.  They rub, or did before I 
rolled the fender lips flat and did some clearance work on the inner rear 
fenders with a BFH - don't force it, get a bigger hammer.
