has anyone successfully fitted motorsport wheels to there audi?

[sam80quattro]

bought some oz rally wheels for my 90q however there group a fitting (i think lol) and the wheels basically have steel inserts for the bolts/studs to go through and there just a steel tube, no radius seat etc, i have considered trying range rover wheel nuts as these have a sleeve on them that i'm hoping will fit down the inserts and then use studs instead of bolts
pics to follow as im sure ive probably described that as bad as i could

Are the studs M12 or m14?

Jag X type have M12 flat faced nuts with a shank to fit down the sleeve of 3/4"
