I want to say THANK YOU to Darin for excellent customer support thats on par with the big companies like HPI . I received all my replacement parts yesterday. The material on the front hubs is definitely thicker. I cant tell if its more flexible though. But I guess Ill find out in time. I would still change the design on the from hinge pin holders though. Instead of the plastic captures they should just be clips holding the pins and that would eliminate that problem.
Thanks again Darin!
