you need to get information:
I'm currently converting the UFO brake rod to Hp 2 from s6 on my Audi V8. Need the exact outside dimension of the HP 2 hub. Because I want to turn off the UFO hub. There are many opinions of 4 and 5mm. Would be nice if someone could tell me the exact measure. Oh, and if there's any place here, I'm sorry, it was too lazy to look...
Thank you very much
