Thanks.  All the owners manual says is the "some models" came with the 195/65-15 91H tires.  And that these models had a 130 MPH speed limiter.  Does that mean my Quattro does not have the speed limiter? (since it was supposed to come with the 205s)  Not that there are many roads around here I usually drive to do 130+ mph on.

Oh well. . .  I guess that will save me some money, though.  I'm really don't want to play with the offset.

Fortunately, I've decided on one of those!  The place I bought the car (AutoSport/Imported Car Center) had a black 100CSQ with the Borbet Type H wheels on it and I really liked the look.  (My 90 is also black).

Most of the tires I've been looking at have pretty old designs.  If I go with 205/60-15, I'm down to the RE71, D40 M2, or AVS Int.  I remember being impressed with the performance of the RE71 when I was codriving back in the mid-late 80s.  I heard good things about the Dunlops and the AVS Int. (liked the A-008s).  Decisions, decisions :-)

Sigh, the mechanic couldn't find anything wrong with the brakes yesterday.  Not sure if that is good news or bad.  They haven't done it again since, but I haven't used them that hard since then either.  Any tips on keeping the handbrake mechanism from seizing?

Is the a service manual for these cars?  Bentley only lists up through 1992.  Do I have to go to the dealer for the manual?  I'd like to know things, like which kind of FI system is on the car, etc. 

By the way, I have the Bentley manual for my 4kCSQ that I no longer need.  It is officially titled "Audi 4000S, 4000CS, and Coupe GT Official Factory Repair Manual: 1984-1987".  What's a fair price for it, $50?  (hardly used it) (Or trade for a service manual for a '94, grin)
