yepperz! 12x1.5

if you're doing it on aftermarket wheels, make sure you get the "thinner" nuts on it. i know i had a set of aftermarkets that wouldnt fit on my current wheels. they were too wide. had to step up to the JDM mutekis.

A 12mm lug is pretty standard for a 4-lug car. Some imports go up to 14mm, but that's usually on heavier cars or models with higher HP/TQ ratings. Even most Mercedes use 12mm lug bolts.

what i find the funnniest part, is that the recommended torque according to our chart at work for the xB/xA is like 78 ft lbs! lol. The bigger chevy trucks are running 140 ft lbs! How does it feel that a Chevy truck require one and a half times the torque on its wheels, than we produce in our engines. Makes me cry a little inside. haha.

12X1.5mm is the thread diameter and pitch.
21mm is the wrench size needed to remove them.
