Sorry panterapatt, I misunderstood you. I did email Roin and asked Andrea to provide me with prices on the matching lug nuts, which he has. Given the hell I went through with UPS in getting the wheels, I really wish I had ordered lug nuts from Roin when I ordered the wheels. Waiting to hear back from him.
Also, when I get home, I will put one wheel on the car and take a picture and post it. That should give a better idea as to how far the studs come through the wheel's holes.
Just want to thank everyone for their input thus far.
