Important
What to Know Before You Buy
Wheel Size Requirements
Big brake kits typically require 18" or 20" minimum wheel diameter. The 2011-2014 Chrysler 300 base models often came with 17" or 18" wheels. Check each kit’s spec before buying.
Pad Options
Many kits offer multiple pad compounds (street, track). Baer and Wilwood offer slotted, drilled, or plain rotor options. Brembo kits include high-performance pads. Choose based on your use case.
Front vs. Rear vs. Full Kit
Front-only upgrades deliver the biggest improvement. For balanced braking, pair a front kit with a rear kit. Baer and Wilwood sell front and rear separately; Brembo offers both.
Brake Fluid & Bedding
Flush brake fluid when installing. Follow the bedding procedure for optimal performance.
Baer 14" Pro+ Front Big Brake Kit
The Baer 14" Pro+ Front Big Brake Kit is the most affordable entry into big brakes for the 2011-2014 Chrysler 300. Baer ships fully assembled hubs with bearings and races pre-installed and packed with Redline synthetic grease, so installation is straightforward. Choose from Slotted Only, Drilled & Slotted, or Plain rotors to match your driving style.
Fits 300 and 300C models (2012–2024) excluding SRT8. 2011 models use the 05-11 Baer Pro+ kit. Requires 18" minimum wheel diameter. AWD models are excluded. Pair with the Baer 14" Pro+ Rear kit for a complete F&R upgrade.
Pros
- Lowest price point for a front big brake kit
- Fully assembled hubs — ready to bolt on
- Rotor options: slotted, drilled & slotted, or plain
- USA-made
Cons

Baer 14" Pro+ Rear Big Brake Kit
The Baer 14" Pro+ Rear Big Brake Kit completes the front upgrade with matching rear stopping power. Same fully assembled, plug-and-play design as the front kit. Balances brake bias and reduces fade when paired with a front upgrade.
Fits 300 and 300C (excl. SRT). 18" minimum wheels. Excludes AWD models.
Pros
- Pairs with Baer 14" Pro+ Front for full F&R

Wilwood AERO6 Front Big Brake Kit
The Wilwood AERO6 Front Big Brake Kit delivers 6-piston front braking for the 2011-2014 Chrysler 300 at a price point between Baer and Brembo. Wilwood’s AERO calipers are designed for street and light track use with good heat dissipation and pedal feel.
Fits 300 3.6L and 5.7L RWD (2012–2014). 2011 models use the 05-11 Wilwood AERO6 kit. Available in drilled or slotted rotors and black or red calipers. Excludes SRT8 and AWD.

Wilwood’s AERO4 Rear Big Brake Kit uses a 4-piston caliper design for improved rear braking and heat dissipation. Available in drilled or slotted rotors and black or red calipers. A strong value for 300 owners who want a rear upgrade without the Brembo price.
Fits 300 3.6L and 5.7L RWD (2012–2014). 2011 models use the 05-11 Wilwood AERO4 kit. Pair with the Wilwood AERO6 Front for the same platform.

Baer 15" Extreme Front Big Brake Kit
The Baer 15" Extreme Front Big Brake Kit steps up from the Pro+ with larger 15" rotors for more heat capacity and stopping power. Same fully assembled hub design as the Pro+ line. Ideal for 300C Hemi owners who want maximum braking without Brembo pricing.
Fits 300 and 300C (2012–2024, excl. SRT8). 2011 models use the 05-11 Baer 15" Extreme kit. Requires 18" minimum wheels. Excludes AWD. Pair with the Baer 15" Extreme Rear for a complete F&R upgrade.

Brembo GT 6-Piston Front Big Brake Kit
The Brembo GT 6-Piston Front Big Brake Kit is the most versatile option for the 2011-2014 Chrysler 300. Brembo’s GT Systems use monoblock aluminum calipers for rigidity and consistent braking. Available in Black, Silver, Red, or Yellow with Drilled or T1 Slotted rotors.
Fits 300 and 300C (excl. AWD & SRT8). The SRT8 300C uses a different brake layout and requires the Brembo GT 8-Piston kit instead. This is the go-to choice for 3.6L and 5.7L Hemi 300 owners.

Fits 300C SRT8 only. Available in Black, Silver, or Red with Drilled or T1/T3 Slotted rotors.
Pros
- Only big brake kit for 300C SRT8
- 8-piston caliper, 380mm rotors

Common Questions
Frequently Asked Questions
Do I need new brake fluid when installing big brake kits?
Yes. Flush and replace brake fluid when installing big brake kits. Old fluid can contain moisture and reduce brake performance. Use fresh DOT 3 or DOT 4 fluid (or DOT 5.1 if specified for track use).
Will big brake kits fit my stock wheels?
Most big brake kits require 18" or 20" minimum wheel diameter. The 2011-2014 Chrysler 300 base models often came with 17" or 18" wheels. Check each kit’s spec before buying.
What’s the difference between front-only and full (front + rear) kits?
Front-only upgrades deliver the biggest improvement since most braking force is on the front axle. Full kits (front + rear) improve brake balance and reduce fade under heavy use. For a 300C Hemi, a front-only upgrade is often sufficient; for track use, pair front and rear.
How do I bed in new brake pads?
Follow the manufacturer’s bedding procedure. Typically: 5–10 moderate stops from 60 mph to 30 mph, then cool down. Avoid coming to a complete stop during bedding. Repeat until pads are fully seated.
Will big brake kits void my factory warranty?
Modifying brakes may affect warranty coverage if a brake-related failure occurs. The Magnuson-Moss warranty act limits manufacturers from voiding unrelated warranties. Check with your dealer if concerned.
I have a 2011 Chrysler 300. Which kits fit?
The 2011 model year uses the same platform as 2005-2010. Baer and Wilwood offer separate 05-11 kits for 2011; Brembo GT 6-Piston fits 2011 directly. For 2012-2014, all kits in this guide apply.
