yes my bodys fit with no modifications. you just have to put the slits in the bodys so they pop on and off the stock mounting tabs. you can put it as low as possible or as high as possible. its up to you...
as far as the tires go. they are supprisingly sticky enough to get you going and keep traction. i didnt even need to add any rubber cement ot liquid latex to the tires to make them grippy!! i think this has to do with how wide they are and the amt of rubber hitting the ground.
so after the mod i didnt have to do anything to the tires. they work supprisingly good.
