330mm 4-Piston Big Brake Kit

This kit features a robust 4-piston caliper forged from aircraft-quality billet aluminum, weighing just over 7 lbs. It boasts larger pistons than ProComp calipers, offering enhanced rigidity and improved pad wear compared to OEM designs. The caliper includes aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. Complementing the caliper is a 2-piece floating disc assembly with a 330mm diameter and 32mm thickness. This design reduces rotating and unsprung weight, while the floating disc construction prevents thermal stresses from warping the disc. The unique slot design on the rotor minimizes braking noise and efficiently expels gas and pad debris. Cross-drilled rotors are standard, recommended for daily driven vehicles for their cooler operating temperatures. Stainless steel, D.O.T. compliant brake lines are included, improving pedal feel and response by preventing expansion under pressure. This Ksport big brake kit is made to order, and customers will receive an estimated delivery time after placing their order. It is important to note that made-to-order items are non-refundable and non-exchangeable once the order is placed. Standard equipment includes Ksport SC5 Street Pads, which are NAOC ceramic pads designed for optimal street and occasional track performance, offering reduced dust and noise. For dedicated track use, Ksport RC5 Race Pads (carbon metallic) are available as an option, though they are not recommended for street use due to their higher optimal operating temperature range. The Ksport Supercomp Big Brake Kit is specifically designed for the Mercedes Benz W212 E63 AMG models from 2010-2017. This includes the E63 AMG with the M156 6.3L engine (2010-2011) and the E63 AMG 4-Matic with the M157 5.5TT engine (2012-2017).
