UFO conversion

[kneale at knitknacks.com]

My 200q20v sedan belonged to the dealer's family before the guy I bought it
from acquired it.  The UFOs were changed for G60s.  They work OK unless
you're in a fade circumstance like a long, steep downhill.  The UFOs on all
my other cars of the same vintage, including the 200q20v avant and two V8s,
were less succeptible to fading under extended use.

Subject: UFO conversion


I am the original owner of my 91 200Q 20V and had Audi do the conversion
under warranty when the car developed warped rotors at speed. Vehicle had
only 5000 miles then. I have in my file the complete Audi tech service
bulletin that outlines the procedure including parts and step by step
instructions. While I believe it should be available thru Audi, if you send
me an address, I can forward a copy. 

Personally, I thought the conversion was the way to go. These are the 92 V8
parts grafted on to our vehicle. Eliminating the bi-metal construction of
the UFO disc is a critical issue. As I have sold brakes professionally for
some thirty years now, I can tell you that these two piece welded
assemblies have issues. Just ask a 1990's era Ford Taurus owner... K-H
created one for Ford and warpage became a big issue due to extra critical
wheel tightening procedures. Service techs were over-torquing wheel bolts
and warping these rotors. Our situation is a bit different, but it is an
overly complicated design. I never lacked for stopping force when using the
Pagid pads.
