I agreed, not worth for those cheap casted wheels. Years back, I bought 4 20" wheels (great looking) at Chicago auto show for my nearly new Infiniti Q45. After a year (only driven in local), the edge of rim started to fall and crack. One day, I ran over a pothole on I-65 freeway at about 70 mph. The wheel cracked right after. My car towed to a small town near by, only one shop would take my car (because of my performance tires). I had to buy four new rims from him and 4 used tires too, in order to drive back home. What messy and nightmare.
