You can run with the 6mm shock towers back and front from rc-badboy on ebay, the PBS difference relates to the hub carriers, i.e they are PBS an not C hub carriers. So no problems with the shock towers.

I think you'll find that the towers are different on the front of the PBS and c hub variants. That said you can still fit the c hub ones to a PBS ok, though you must use the upper hole for the top arms.
