[urq] UrQ SUb-Frame(s)

[Louis-Alain_Richard at computerhorizons.com]

For Martin D,

If I'm wrong, then Martin P. will correct me, as usual :-))

On our urQs (1982 to 1987, North-America), there is 2 different subs 
(early and late), 2 different swaybars (with an annular groove and c-clamp 
or with a loop-end and end-link) and 2 different a-arms (with slot for 
c-clamp or hole for end-link). As Martin said, cut date is around mid 1983 
that is 85-D-900600.

The only visual (and maybe functionnal) difference between the 2 subs is 
the way the swaybar is bolted to the sub: with a small c-clamp (1 bolt) or 
with a bigger bracket (2 bolts) à la 4000Q/90Q (see TFA ). I think any 
swaybar can be installed on any subframe, providing you have the correct 
brackets and bushings for that subframe. Be aware that the early style 
bushings are NLA at Audi, however www.audipoly.com seems to sells some 
poly replacement units.

The sway bars and the a-arms goes together unless you modify the a-arms to 
accept the other swaybar attachment. But they are independent of the 
subframes, functionnaly.
If I am right, the only difference between the old style a-arms and the 
newer units is the hole for the swaybar attachment. Except that, they are 
dimensionally identical.
Then, to install a newer swaybar on an older style a-arm, you just drill a 
hole (and reinforce the area maybe ??) into the a-arms to connect the 
end-links. 

If one wants to see all that blah blah illustrated, just open TFA to 4, 
11, 36-00 for our cars and all this will become clear...
For those without TFA, I can send a PDF version of the page, if need be.

[urq] UrQ SUb-Frame(s)






     I read with interest all the recommendations on this subject but 
found 
it difficult to sort the complete situation due to references to control 
arms 
etc. Basic questions for someone to answer please relating to just the 
subframe(s):

     1.  Are the 83 sub-frames unique to the 83?
     2.  If the answer to 1 is NO can they be replaced, without 
modifications, by a sub-frame from some other model?
     3.  If modifications are required, which model sub-frames can be used 

and what are the modifications?
 
     Thanks
