Description

The Ksport SuperComp Big Brake Kit is engineered as an extreme brake upgrade for the 2003-2008 Nissan 350z, providing a significant increase in stopping power over factory systems. Constructed for performance and racing applications, this kit features 4-piston calipers with a 1-piece billet aluminum body, offering light weight, exceptional strength, and corrosion resistance. The calipers house aluminum pistons for better heat management and smoother operation. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers bolt directly onto the existing mounting points without modifications. The rotors are a 2-piece vented design with a 330mm (13-inch) outside diameter and a cast iron braking surface with a drilled finish and aluminum center to reduce rotational mass and improve response. The opposed-piston caliper design enhances pad grip and minimizes uneven wear, while heavy-duty caliper seals are built to withstand sustained high-temperature track use. Stainless steel brake lines are included to prevent expansion under pressure, leading to faster pedal response. Key specifications include a minimum wheel diameter requirement of 17 inches (432mm), street-oriented brake pads, and a fixed hat construction. The kit is intended for performance driving styles and is sold as a 2-piece set.
