i also put this in the other wheel forum to get as much help as i could.

i just got a set of 5Zigen (acorn shaped) 19mm lugnuts for my Volks but they look too big. Anybody know if 19mm is too big before i send them back?

thanx,
chris

 

already answered.

 

12mm x 1.25 is the lug nut threading.

 

it wasn't that which was the issue. it was the outter diameter of the lugnut. but i made a few calls and found out that the GT-c's come with their own lugnuts.

thanx,
