It depends on what, exactly, you are after!
The standard GTI has a separate lower lip - about 2/3rds of the total width, each end finishing below the centre of the two outer fog lamp grilles - part no 1K0 807 110 9B9 - pimply satin black, £29.22. This actually looks fine when painted (painted properly though!).
The lower lip screws into the bottom part of the bumper - roughly the bottom two inches, and goes all the way round to the wheel arches - p/n 1K0 805 903 H 9B9, again pimply satin black, £30.57. Again, looks fine painted. This is actually a b!tch to remove from the remainder of the front bumper - you will end up snaping the locating tabs, but if you have a plastic weld gun, you should be OK.
The Ed30 is a one piece unit - the bottom section of the bumper includes the lower lip. Part no 1K0 805 903 J GRU - grey primed, £198.00 - which is quite a lot of dosh, when painting the standard GTI bits looks nearly as good!
