I came across this thread on a foreign forum

Someone has this brake setup:
Fronts
ST185 Single Piston calipers
Redrilled ST185 front brake rotors
Rears
Late model SW20 turbo calipers, part number 22V
Front AW11 rotors with a spacer between the hub and rotor
"the SW20 calipers bolt straight up to the AW11 rear hub carrier. The caliper mounting tabs on the hub carrier aren't as long as on the SW20 carrier though which is why I ended up running a smaller rotor than the SW20"
The rear setup looks good as it appears the calipers don't need welding and it uses stock mk1 discs. I wondered if anyone here has tried this, and what size spacer is needed

so the answer is yes ans I need a 6mm spacer. Guess I can use an off-the-shelf spacer as mk1 disc will align on hub. I think this should be in the brakes conversion table.... good alternative to the hassle of welding/grinding etc to get the g60 discs on.
