hey i put some lego wheels on my xmod like stock wheels (bolted on) the fit on the same way as stock wheels do and dont stick out like they would if i glued them to the stock wheels. i did it by drilling a big hole in the lego wheel and then cutting a hole in a piece of plastic that would fit on the xmod axle. then i glued the platic piece in the lego wheel and used the hole in the lego wheel to stick the wrench in to tighten the bolt down. heres some pics of just the front done ill post some of the back later this afternoon
