Which lugnuts do I need for the Z06's. Acorn?

 

12x1.50 acorn seat

try to get some with a 19mm head so you can get them off with your spare tire tools

 

The acorn is the same as conical seats aren't they?

 

yep

 

My Z06s came with lug nuts that weren't all the same size so i just went to oreilys and bought some 12x1.5 acorns. Only thing is they are 3/4inch wrench size i do believe. It worked out though because that is the same size as my locking lugnut socket.
