So after the last 2 days I have done my grill, I will add that I experienced some unexpected teething problems! I will add this to the bottom of this post.
Its done along with painting the Grill trims gloss black!
Now this is a job I would not call easy, this TTRS grill does not plug and play with a TTS no matter how many times you look at it offer it up, and you have to remove the bottom grill on the TTS bumper (which is an absolute bitch to get out because it has hidden very very tough clips) and then you basically chop it in half so you free up the top recess in the bumper for the TTRS version to fit!
Some other things to consider. Paint the crash bar black even if you get the OEM Crash bar cover, it will show otherwise.
The Standard front Parking sensors are grey in the TTS grill so they will need to be painted Gloss Black
There is an OEM bar that fits back on the top of the grill that hold some electrics, you need to cut this down flush or you will see it through the grill.
Any wires and electrics that are not routed with care will be seen through the front grill.
This is not a novice job, I nearly smashed the grill up a few times trying to get it to fit, but I persevered but now have smashed up fingers, nails and back as a result.
