Baer Brakes Disc Brake Kits: Race-Proven Stopping Power for Every Build

When it comes to disc brake kits, few names carry as much weight in the performance aftermarket as Baer Brakes. For over 30 years, Baer has been pushing the boundaries of performance brake technology from their Phoenix, Arizona facility — engineering, machining, and finishing every kit entirely in-house, with materials sourced from the USA.

What sets Baer apart in the disc brake kit category isn't just hardware — it's a purpose-built system philosophy. Each Baer kit is designed around a specific performance goal, covering everything from affordable street upgrades on classic muscle cars to full race-specification big brake systems. The result is a lineup that addresses virtually every build type with a matched solution.

A Series for Every Application

Baer organizes its disc brake kits into clearly defined series, each engineered for a particular level of performance demand:

• Classic Series — The entry point into Baer performance. Featuring two-piston front and single-piston rear calipers paired with cross-drilled, slotted rotors, the Classic Series delivers modern stopping power while maintaining a traditional aesthetic. Each kit includes rotors, calipers, pads, hoses, and all necessary hardware for a complete bolt-on installation.
• SS4 & SS4 Plus Series — The SS4 line steps up to four-piston calipers in rotor sizes ranging from 11" to 13". The SS4 Plus variant upgrades to lightweight two-piece rotors, reducing rotating mass while improving heat dissipation. These kits are designed to fit behind most 15" and larger wheels, making them a popular choice for street performance and autocross builds.
• Track4 Series — The 13" Track4 kit targets drivers who split time between street and track use, offering outstanding heat management, consistent pedal feel, and modern braking response through four-piston calipers and large-diameter rotors.
• Pro and Pro Plus Series — Stepping into six-piston territory, the Pro and Pro+ lines feature Baer's 6P six-piston calipers with rotor sizes from 13" to 14" and optional two-piece rotor construction. The 14" Pro Plus, for instance, is engineered specifically for performance street, autocross, and open-track applications, with premium slotted and drilled rotors, stainless steel hoses, and all installation hardware included.
• Extreme and Extreme Plus Series — At the top of the lineup, the Extreme series pairs 6S six-piston monoblock calipers — the type used in professional motorsport — with massive 15" rotors for uncompromising stopping power on the most demanding builds.
• Deep Stage Series — Purpose-built for competitive drag racing, the Deep Stage kit is engineered to reduce rotating mass without sacrificing braking performance, prioritizing quick serviceability and lightweight construction for strip applications.
• 6T Series — The 13.5" 6T kit is Baer's answer for trucks and off-road vehicles, featuring heavy-duty 6P six-piston calipers and large rotors built to handle serious loads across demanding terrain.

What Makes Baer Kits Different

Every Baer disc brake kit is precision-machined and assembled in-house in Phoenix, AZ, giving the brand tight control over fit and finish. Caliper powder coating — a Baer signature — is also performed in-house, with standard finishes in red, black, and silver, plus an extensive range of custom colors. Baer is widely credited with popularizing the red performance caliper look that has become an industry standard.

Kit completeness is another hallmark: Baer kits ship with rotors, multi-piston calipers, performance brake pads, stainless steel hoses, and all mounting hardware — everything needed for a professional-grade installation. Vehicle-specific fitment across a wide range of American muscle cars, GM A-Body and F-Body platforms, Ford Mustangs, classic trucks, and modern performance vehicles means less guesswork and a more direct installation experience.
