my GT2 bumper is made by TTP and it is a perfect fit. They really didnt have to do too much to modify it to make it fit, other then make a couple of the holes for the screws a little bigger. I cant wait to get it back with the rest of the Gemballa body kit after this weekend.
And to answer your question yes it works on a S too. I do k now someone else with an S who has it too.
From all of the bumper choices out there this is the only one I truly like
