I made the 3d model in 3ds Max, I'm not looking for what to use for the control arm, but I'm looking for a cheap way to hook up the suspension arms to the wheel hub for strong support, I'd rather buy some like ball sockets, rather then making my own

as for the speed controllers, I need at least to because the Mako in the game combined steering and tank like control at low or no speeds. I cant have all the motors connected the same way because then each wheel would need different gearing inside
