back when I was heavy into z cars, one of the members passed this on to the board members. I was'nt intrested so much about the touring scene but, I did take interest on the Konig discount prices. 55.00 bills for any 15 inch and 75 for 17 inch wheels and they where delivered to your house. On of the members got her 4 15 inch wheels for her Z for under 300.00 to her house. Know I don't know if they have any that will fit our cars here, but it might be worth looking into.
