Important
What to Know Before You Buy
Wheel Size Requirements
Big brake kits typically require 18" or 20" minimum wheel diameter. The 2005-2008 Dodge Magnum 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

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 2005-2008 Dodge Magnum 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 Magnum R/T 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 Magnum SRT8. What are my options?
The 6.1L SRT8 uses a different brake layout than the 2.7L, 3.5L, and 5.7L models. Baer and Brembo offer separate SRT8-specific kits. Contact us for fitment on SRT8 applications.
