Thanks Joe for putting the link to Diamond for Sean. You beat me to it!
Sean,
Yes these are the Diamond Avenger series wheels. They are the 5x130mm bolt circle and have the standard lug taper, you can use them with the stock lugs and steel or aluminum acorn nuts.
On the Diamond website they quote $120 each wheel which includes either a silver or black powdercoat. Diamond adds a surcharge depending on the cost of steel at the time you order. That's why my wheels turned out to be $137 each. If you want them chromed or powdercoated a different color, you pay more.
The backspacing comes in 1/2 inch increments. I have to admit that they look alot better inperson than on the web, I'm impressed.
These things look to be put together pretty well. The welds are nice on the center section against the bell.
Hopefully the car will be up and running in the next 3 months and I'll get to try them out!
Bill P.
