IMO, carbon graphite upper deck/towers are uneeded and not as strong. Super chassis isn't really needed - just a different grade aluminium - same thickness, and the tank has a built in ceramic fuel filter.

That only leaves the ti turnbuckles and threaded shocks left on the hpi option parts! I wish they'd added the threaded shocks to the kit though - they are trick! Ti turnbuckles sound nice, but it would have added a lot onto the total price to manufacture. I'll probaly just get the rear MT2 threaded shocks in immediate future for rear of my rush evo, then in a few weeks when I get it I'll only need the front pair. They really will be the finishing touch!
