Quick question—are you still running the stock 18-inch wheels, or have you upgraded to 20s? I honestly had a nightmare experience with StopTech Sport Slotted Rotors on my heavy sedan because they just couldn't handle the heat under load, and unfortunately, they warped way faster than I expected. tbf, it might've been my driving style, but I'd love to know your wheel size before suggesting a better setup!

Hi there! I'm honestly so excited to see another HEMI owner looking to level up their stopping power! Before I give advice, curious about one thing: are you still using the original rubber brake lines? When I first started working on heavy cars, I realized that even the best pads can't fix a spongy pedal if the lines are old and expanding. Anyway, since you're on a budget, have you looked into the PowerStop Z26 Street Warrior Brake Kit? It might be a safer, more heavy-duty alternative to the Z23 for a big sedan! Good luck!

Hey! I totally get that frustration—the 300C is a heavy beast, and those stock brakes definitely feel like they're struggling once that HEMI gets moving. I've been through a few setups over the years, and for your budget, I'd say skip the BBK; it's overkill for street use and way over $1,200 anyway.

In my experience, the absolute sweet spot for this platform is the PowerStop K2164-26 Z26 Street Warrior Brake Kit. I've run this on my own heavy Mopar for years and it's fantastic! The Z26 pads have a bit more bite than the Z23s and handle the heat much better without that annoying brake fade. Plus, the drilled and slotted rotors really help with dissipation. Honestly, if you want something even more aggressive, you could pair those rotors with EBC Brakes DP41722R Yellowstuff 4000 Series Brake Pads, but they can be a bit dusty.

Don't forget to swap in some Motul 600 Dot 4 Brake Fluid while you're at it to fix that spongy pedal feel. It makes a huge difference! Good luck with the upgrade!

Basically, for a DIY job on a heavy car like the 300C, you need components that can handle high thermal loads without going soft. High-carbon iron is usually the best bet for rotors because it offers better damping and thermal capacity than the cheap entry-level kits you find at most shops.

• Hawk Performance HPS 5.0 Brake Pads - these work well because they provide more torque than stock but stay quiet enough for daily driving.
• DBA 4000 Series T3 Slotted Rotors - these use a pillar vane design which is much more efficient for cooling a heavy sedan compared to standard straight vanes.
• Goodridge G-Stop Stainless Steel Braided Brake Lines - swapping these is a decent option if you want to eliminate the expansion you get with old rubber lines. The DBA rotors include heat-sensitive paint markings which helps you monitor if youre pushing the temps too high. Since youre doing the work yourself, just make sure to clean the hub surface thoroughly to prevent lateral runout. If you need the specific torque values for the caliper bracket bolts, let me know.
