Adds Huge Stopping Power and Braking Performance to your Mustang

Getting absolutely brutal levels of stopping power for your 2015-2019 Mustang is never a bad thing, and Wilwood's AERO4-MC4 14" Rear Big Brake Kit is your aggressive Pony's one-stop-shop for absolutely ridiculous levels of stopping power. The Wilwood AERO4-MC4 Big Brake Kit combines a pair of Wilwood AERO4 race-inspired 4-piston brake calipers with massive two-piece 14" rotors with either a slotted or drilled and slotted surface that work together to provide a massive improvement in stopping power over the factory braking hardware. The kit even includes one of Wilwood's MC4 mechanical parking brakes and parking brake cables. The Wilwood AERO4 Big Brake Kit will instantly give your Mustang that late-braking stopping power you need to dominate on the track and have some fun on the street. Wilwood even includes a set of their Flexline Braided Stainless Steel Brake lines with each AERO4 brake system.

Forged Aluminum Calipers with 6-Pistons and Choice of Finish

The AERO4 calipers that make up the heart of this package feature a racing-inspired design and a durable construction that provide excellent braking performance and longevity. Each caliper is made out of high-strength aluminum, and are crafted using a specialized stress-flow forging process before being fitted with stainless steel pistons. The caliper features internal fluid ports which eliminates the need for external cross-over tubes or a large bridge which can add weight. The calipers comes standard with a set of Wilwoods BP-10 brake pads, which provide excellent stopping power and a flat torque curve without being overly hard on the system's rotors. The calipers are available in either a black or red powder coat finish, or a nickel-plated finish.

Two-Piece Rotor Design with Aluminum Hat and Cast Iron Ring

Each AERO4 Kit comes with two Wilwood SRP-Series 14" brake rotors with a heavy-duty, performance-minded two piece design. The SRP rotor rings feature a cast iron construction, and can come with either a slotted or drilled and slotted surface. All exposed areas outside of the contact patch feature a black e-coat finish which helps prevent corrosion and improve overall rotor lifespan. Each rotor hat is made out high-quality aluminum alloy which saves you weight versus a solid one-piece iron rotor and comes standard with a black e-coat finish for protection against corrosion.
