the towers were designed to be able to slam the body, so they had to be low. in addition to neglecting track width, most foam races (even some national races) won't tech body height. infact, i have taken a file across the top of the tower and flattened off the ears, where all that extra material is. i'm not sure why they decided to make the rears 1-2mm higher. maybe just so you don't have to do those mods to both ends...

anyway, makes the car look two tenths faster, if nothing else.
