tj- just letting you know, if you're planning on using these on your nismo (sport 19's and 18's included) wheels the studs could break as the 10mm kics do not have the centering ring. if you're using on lugcentric wheels (aftermarket) they work just fine if they have clearance for the protruding stuck studs.
actually i have the exact 10mm kics on my G35C's front wheels right now.
