AS usual with this question it can be confusing, yes it fits but i dont think they do a zorst trim that lets you keep your back box where it is, you will need to replace your back box with a R32 type or get the zorst very bottom piece modified a bit.
Oh i see I always thought it didnt fit into the R32 bumper i remember reading ages ago on one of the american forums about a guy who plastic welded the middle cut out, and made a GTI one. Oh well thats useful to know cheers Joe.
