Thats what I have but the studs on the car stick out to far for the spacer to fit flush?
The stock studs are sticking through the spacer about 1/2 inch. So the wheel will not sit flush against the spacer. Do I need shorter studs?
install the lug nut before you grind so when done grinding, removing the lug will straighten the threads.

you have it backwards! I snapped 2 sets of studs then bought the studded adapter and haven't had a problem. BUT if you have some serious HP adapters need to be steel made by a machine shop.Thy type of spacer you are using is VERY weak and WILL break unless you drive like an old lady.
Do it the right way, Buy a standard spacer (no lugs in it) and get aftermarket longer lugs in your rear axle.
I assume this is a cosmetic thing your trying to do, because there is NO performance gain from doing this.
Your $$ is best spent elseware...
Get some lowering springs.
