Pro touring wheels

Something wrong with the web site. I bought them there at $93 each (new).

Tire rack is $159. http://www.tirerack.com/tires/tires...SUPERCAR&vehicleSearch=false&fromCompare1=yes

I heard they are used in some racing series, produced in big batches or something and extras sold at a discount. I think I'll get an extra set while they are available.
