I would stay away from the 14mm with the GST or the Nemesis 7.7. The smaller wheel hexes can not handle the torque and will strip out. I would go with 17mm or 23mm, 17mm will give you more wheel and tire options than 23mm
yeah i wanted to mention this earlier but i did not know what the kong rims were made out of so it is far better to keep mouth closed and appear stupid than to open it and remove all doubt... if the rims were alluminum they would prob. be fine but not if they are plastic
