Re: question for a2vr6'ers (qka2)
If you want 11" front brakes then the G60 4lug is fine, all you need is the uprights (spindle) fron an A3 or late A2, calipers with carrier, brake hoses and rotors. If you want 11" 5 lugs, then the Corrado VR6 or early A3 VR6 upto 95. spindles, calipers with carriers, hoses, and balljoints, plus suspension (VR6 control arms) with swaybar. You can also get the same VR6 spindles, calipers with carriers, brake hoses, and VR6 balljoint from a B3/4 Passat. You just can't use the swaybar or the control arms with the A2.
Now if you want the 11.3" DE brakes, the 96+ A3 and B4 Passat have them, you need the calipers with carriers, hoses, spindles, balljoints. Note: You will need VR6 Corrado or A3 VR6 control arms, swaybar and axles for the 11.3. You cannot use the B4 Passat control arms, swaybar or axles (keep the joints but not the shaft as spares).
Rear is easy, just replace the rotors.
You will need the 22mm M/C, or opt to add ABS from the Corrado, B3/4 or A3, these have the 23mm M/C.
Prices vary from scrappers, shop around, just note that you may have to rebuild the calipers since you don't know the condition of the items.
Caliper kits run about $15 for 1 caliper, it's easy to do.
