Brake upgrade - rotor size?

[TXExplrPlt17]

2017 Platinum. I'm going to upgrade the brake kit to a Power Stop Z36 (had a Power Stop on another vehicle and loved it). Question: do I have 325mm or 352mm rotors? I thought 352 because of EcoBoost, but was told that I have the 325s because the 352 is only for law enforcement. Any input? Thanks ahead of time.

I´m pretty sure you have the 352mm rotors, the same as the Sport. I believe you don´t need any upgrades for the brakes. What is that you feel the brakes lack or what do you want to improve?
