I am awaiting my 2017 RT plus w/ STP, and am already cannibalizing my 2013 R/T. I am taking off the MOPAR strut tower braces and bought slotted rotors, Red Stuff pads, steel brake lines and caliper covers. As far as the engine bay is concerned, I took out my catch can and polished it up. I pulled out the Moroso coolant tank along w/ the blue silicone coolant lines. I have billet tech dress up pieces. Some were from my '07 and some from my '13, but pretty much made a complete dress up kit. They were in satin and in pretty sad shape. So, I decided to rough them up w/ sandpaper. I then gave two coats each of high temp ceramic primer, low gloss black and clear coat. I wished I would have taken before pics, and I don't know which items will or will not fit the '17. I don't even know how they will hold up....but I figured out I might as well try. Also got a new braided line kit coming from Speedlogix. Let me know if anyone has done this as well.
