I went to my tire shop and they ordered some chrome lug bolts from the manufacturer and it only cost me $70. I would have tried that first if I were you.
I didn't know that you could order them from the dealer. Will they still have that dished center or will they have a smooth ronded cap, which makes all the difference? Be sure to post pics of them when you install them.
I just went to expert tire and they called their guy and said he needed bolts for a porsche boxster, 10 shorter ones and 10 longer ones. They are smooth on top, and have a different taper (straight) because of my new rims.
