Show original supplier description
The Ksport Slimline Big Brake Kit is engineered for BMW 3 Series vehicles, offering a significant brake upgrade that addresses common fitment issues with aggressive wheel choices. Many aftermarket big brake kits struggle to clear factory or closely-fitted aftermarket wheels due to the caliper's size. Ksport's Slimline Caliper design, inspired by the thickness of OEM single-piston calipers, ensures compatibility with a wider range of wheel setups, including those with very limited brake caliper clearance. This specific kit, the BKBM010-312SO, includes 286mm slotted rotors and a 3-piston caliper system. The slotted rotor design helps to dissipate heat and reduce pad buildup, contributing to consistent braking performance. The 3-piston caliper provides increased clamping force over stock braking systems, leading to improved stopping power and reduced brake fade, especially under demanding conditions. This bolt-on upgrade aims to provide a sophisticated performance enhancement that is both effective and user-friendly for enthusiasts looking to improve their vehicle's braking capabilities.
