Slimline 3-Piston Front Big Brake Kit

The Ksport BKMZ320-342SO Slimline Big Brake Kit is a front 3-piston brake upgrade specifically engineered for vehicles running aggressive wheel fitment where caliper clearance is severely limited. Traditional big brake kits often feature thick, multi-piston opposed calipers that cannot fit between the brake caliper and the inner barrel of a flushed or aggressive-offset wheel. Ksport addressed this challenge with the Slimline caliper, a 3-piston single-side design that mimics the profile of an OEM floating caliper while significantly enhancing braking performance. Key features include a 3-pot single-side caliper that provides multi-piston braking force within an OEM-equivalent thickness, making it compatible with most factory wheels and those with tight brake caliper clearance. The caliper is constructed from lightweight forged aluminum, offering a larger brake pad surface area for improved stopping power. It includes 13.8-inch (350mm) two-piece slotted rotors with a floating design and an aluminum center hat to reduce unsprung rotational mass and improve braking response.
