The wheels are RacingHart CX 18x8 +10mm offset 
(Tires, Sumitomo 225/40x18) ordered  
by a Norwegian dealer with contacts in Japan. 
i have original suspension and there is no need for spacers.  
i had to do some machine work on the front hubs, the center hole on the wheels where to small in diameter to fit.
