Dual-Caliper Handbrake & Footbrake Kit

This innovative system employs a single 4-piston caliper, with two pistons dedicated to the primary foot brake and the other two independently operating the handbrake. This design enhances pad grip and minimizes uneven wear. The kit is a complete bolt-on replacement, requiring no modifications for installation. Constructed with performance and durability in mind, the kit includes 4-piston calipers with aluminum pistons for corrosion resistance and lighter weight. The reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers mount directly to existing points. The 330mm (13") rotors are a 2-piece vented design with drilled surfaces and an aluminum center hat to reduce rotational mass, improve response, and shorten stopping distances while minimizing warpage. Heavy-duty caliper seals are rated for sustained high-temperature use, and stainless steel brake lines prevent expansion under pressure for faster pedal response. This kit is designed to fit 2008-2014 Subaru Impreza STI models. It requires a minimum wheel diameter of 432mm (17") and comes with street-performance brake pads. The kit is finished with orange calipers.
