Can't help but notice the part numbers appear the same for the 2016.

Indeed, they will fit. Its a regulation issue. For patten parts for cars after 2016, the discs need a test certificate. This costs a lot of money and basically, they are sent to a test lab in Germany, loaded onto a sim and then tested with the appropriate hp. So thus, I can only market them to 2016.
They are covered in full by the manufacturers indemnity and warranty.
To give you further info. The OEM front discs on the GTS are dual cast, ours are solid and a kilo or so more. The Chrysler 300C SRT8 runs a solid disc that fits on the GTS hub but the offset is wrong. The SRT8 is of a similar HP to the GTS.
The SRT8 runs a 6.4 392 Hemi
engine with 470 hp and weighs 1835kg
The GTS runs a 4.7
engine with 454 hp and weighs 1880kg
So basically, you have two cars here that have the same underpinnings (Fiat Group Chrysler). One has dual cast, the other solid (as per our SM proposed discs) so there is no issue with running solid discs.
Further to this our discs are high carbon so extremely strong and I am still of the opinion that the warping issues with the OEM front discs are down to the fact that the discs are dual cast and each metal reacts differently to the extreme temperatures put through them...the same way it does with a bi-metallic strip.
