GorillaAutoHey @Artsan, @GorillaAuto is spot-on...but you can do yourself a huge favor and install studs! I have a 2001 Audi S4 Avant and I'm so happy I ditched lug bolts in favor of studs. If you do that, I recommend going with open-ended nuts so you don't have to worry about the length of the studs and whether they will hit the top end of the bolts. And don't forget the red LocTite...on the studs/rotors, not the nuts!
