Wheel Studs

Does anyone know the proper size stud on the 2012 regal GS? I'm installing aftermarket wheels and I'm looking to upgrade the studs as well since I'm going with a different offset. All of the websites I look on say it's an m12x1.5 with a .501 knurl. I'm pretty sure it's actually m14x1.5 with a .630/16.01mm knurl. Anybody have any input on this?

Not sure about the length, but it definitely is an M14 stud.

Dont bother with studs. I run my car on aftermarket wheels with a wider offset and have had zero problems. 19x9.5 all around withba 21mm offset. The studs are 14x1.5. Save yiurself the money you dont need them. Buy hubcentric rings for your new wheels and make sure they are balanced/on the car properly and you wont have any issues.

How thick is the spacer you have on?
