G60 Conversion on `89 90 Quattro

[JShadzi at aol.com]

    Ok, thanks for the clarification on the 20v Sedans.
    I have thought a lot about the A4 caliper, and even did some 
measurements.  Basically, the A4 caliper has the same offset as a G60.  The 
problem is, the A4 uses exclusively a 288mm rotor in the US.  In Europe it 
was offered in a smaller solid rotor, so the correct part may be available.  
Overall, the best bet on a type 44 would be to use the A4 rotor and caliper.  
The A4 caliper is 5 lbs lighter than a G60 BTW.
    You could likely use the a4 caliper, but the pad would overlap the rotor 
by a few mm on the outside-not the best way to do it.  I bet you could find 
an A4 owner who had done BIRAs or something that would send you a rotor and 
caliper for test fitament.  Honestly, though, I don't think it will provide a 
huge improvemnt in braking, the BIRA set up is good for that.

<< Right on, Javad, except that the 20v sedans didn't get the G60s in the
 US. Euro versions had that option, apparently, which is why we can get the
 funny offset 276mm 4x108mm rotor with a factory part number.
 
 One option that I want to investigate is the possibility of mounting A4
 front brake calipers and a 276mm rotor onto my 20v sedan. The A4 caliper
 should bolt right up to the strut housing (same spacing) and the specs
 call for a 276mm rotor on the A4q sedan. Unfortunately, there seems to be
 some confusion, as Ti Kan reports that he had a 276mm rotor (5k-style) and
 an A4q rotor hand in hand and the A4q rotor was more like 288mm. Weird.
 
 Any thoughts on the A4 front caliper setup? There have GOT to be some
 availble from the rich people on audiworld.com :>.
