I want to install a set of 2021 Charger Hellcat Widebody brakes on my 2017 Chrysler 300s. I am concerned because the knuckle part # is different on the 2020 and up models. The only information I see is they are now 15.7" rotors instead of the older 15.4" because of the copper being removed from the pads. I know the 2019 and down Brembo brakes will bolt right up as long as the knuckle in the front and the hub in the rear are used. Just wanting to confirm if this holds true for the 2020 and up models?

Interesting. I wonder if there are any pads that are as good at braking under ALL conditions that either still have copper (why? Does it cause Global Smarming?) or produce lest dust.

From an article:
.

Most brake pads still contain copper, which has been proven to be harmful to the environment. However, Bosch’s QuietCast pads are copper-free. These brake pads also produce little noise and brake dust and have a longer life due to their rust and corrosion resistance.

Brake pads that have a longer life due to their rust and corrosion resistance?

Really? Copper in a brake pad makes it rust? Is there anyone, anywhere, who has EVER experienced a rust problem with their brake pads?

Isn't that like gold in a watch making it overly magnetic?

I mean, the Bosch pad ad copy sounds good, but the rust bit, really? Ima look at the Bosch pads and see if they make any for the Hellcat. They usually make good stuff.

I found the Bosch pads on Ebay. They seem affordable, and they evidently boast of being quieter and cleaner. Hmm.

Rust post wash that came off after a drive, but I will say the DBA rotor rings will rust near the hat (Where the pad doesn't touch) if it ever hits water. I installed mine, then took them off to tape and paint the diameter because I DESPISE rust.

2021 and up. 2020 brakes are the same as the rest.
