Looks like it's just as tall on the front. They follow the shape of the floor. Driver has a fake pedal on the left and a real pedal on the right.

I never had a problem with too much water/snow with the OEM rubber mats and prefer that they lay flat and don't try to climb the sides.

On a couple occasions I've dumped them out before water got too deep and when enough dirt got on them.

I have a set of e53 OEM somewhere. (From when my e53 was deer retired).
