So, I just got a t-maxx that came with these, how the hell do I install these things? They have a grub screw and from what I've seen they have the pin that is stock in them also. Do they just go on like stockers, if so wtf is the grub screw for. I see pictures of them all over as I look for instructions for installation. Help me out so I can get these badass rims and tires on my truck
