Building the kit and I have a question. How much play should there be in the front arms? They have at least 1mm to 1.5mm of it the rear barely had any play. Just seems to me that's a lot of movement on the hinge pin's. The hinge pin holder screws are as tight as I can get them equal amount of play on each side. This is my first Tekno last couple cars I had were Mugen and Xay which came with shims for the arms.
