[Es2] 5 X 112 hubs for '90 coupe quattro

[Ben Nesbitt]

When I did this swap (URS4 front hubs) on my '93 90 quattro, the offset
screwed me up bigtime.  I had measured everything before hand but the setup
did not work at all and I was baffled, really.  I thought I could use URS4
rotors and 1/8" spacers under the caliper carriers, but that was not to be.
the extra offset on the rotors made them hit the hub carrier and the only
solution was to drill 5 holes in my oem 90 rotors (same offset as S2) and
put 1/8" spacers under the caliper carriers.  This is after I had the base
of the URS4 hubs machined down so they would seat into the '93 90 hub
carriers.

I had at my disposal, nearly every caliper and rotor that Audi had ever made
and this was the only rig that worked.  I have not had a chance to try the
A4 front hub, but if you are planning the 5x112 conversion, the S2 front
hub/rotors are highly recommended by me,  Kung_Fu_4.2. Ex business advisor
to Achtuning and insane installer of a 4.2 liter V8 in my '93 90 quatt...not
done yet.

FYI, the URS4, coupe and B4 90 quatts use identical caliper carriers, but
the URs uses different calipers and rotors.  God only knows about the hub
carriers.  A guy I know - Rich, in Seattle - used an A4 Stoptech kit on his
coupeGT so maybe the A4 hub is the answer for the front.  The A4 REAR hub
and rotor are golden, but the front is snake-bit.
