the reason i thought the camber was adjustable by the strut housing is the two bolts that hold it to the hub.on most other cars thats where the camber is adjusted,by the slotted mounting holes.do any of you other guys with lowered audis experience much tire wear on the inside of em'?
The axles are different between the 90 and 4kq so you'd have to swap those I think... the 4kq uses a nut while the 90 uses a bolt (plus the splines may or may not be different.. not sure there).
No adjustment happens on those lower bolts... as far as I know they are just there to make removing the hub a relatively easy task. As Nate mentioned, the brake caliper mounting holes are different so you'd have to use 90 brackets.
HTH.. I plan on using type 89 FWD struts on my 4kq so I can use the BIRA brackets.. all the other 4kq suspension stuff will bolt up to those.
