there is a plastic cover for the towing eye that you remove to get to it. i much prefer getting towed forwards 
tell you what ur funny arnt ya.
I mean on the front if u do the conversion and then dont cut the rectangle of the metal part of the bumper you are going to have problems if you want towing from the front as u can only see a small part of the towing eye and it isnt enough to fit a tow bar through due the thickness of the new big bumper rather than the small ones.
funny fatherless son.
that is only an issue your golf must breack down lots, mine dosent. towed quite a few big bumper golfs before its not exactly that big of an issue.
anyway i prefer the look of big bumper golfs as long as bumpers are fitted properly the gripe i have with them is the lower air dam, it's a bit east to snap / rip off. don't think the frount one is any heaver than teh small buper ether if you count in the bits of body that can also be lost when fitting big bumpers
