UR quattro conversions

["mike" <mike@genesis-microchip.on.ca>]

     I was hoping someone out there could help me with a couple of things 
     regarding ur-quattros. I realise answers to my questions may well be 
     archived and if this is the case, I'd just appreciate being pointed in 
     the direction of the relevent archive.
     
     Could someone describe the Abt and/or Treser body kits for the 
     ur-quattro? I am particularly interested in the material the kits were 
     made from and what parts of the car were modified. I know what the 
     Treser convertible looks like... and I won't say any more.
      
     I'd also appreciate e-mail addresses of any ur-quattro owners, who 
     either perform their own maintenance, or have had their cars 
     performance "modified".
     
     Thanks in advance, Mike (mike@genesis-microchip.on.ca)
