D2 Racing Sport Front Brake Kit – BMW 3 Series F30 316I 12-18 (PCD 5 X 120) BM73-1

Description

Our upgraded D2 brake kits are designed for optimum braking performance, resulting in reduced brake distances and better brake feel in performance vehicles. A Big Brake Kit (BBK), is also known as an Upgraded Brake Kit or Performance Brakes, is composed of bigger brake discs, brake pads and calipers. Braking performance is linked to the surface area the brake pads have to bite into, as well as the disc diameter and pad pressure.So larger pads and larger brake discs are perfect for shorter stopping distances. This increased surface area also helps with heat dissipation, as heat is the enemy of braking performance. The number of pots (or pistons) of the calipers will also play a role in term of pressure applied on the pads to make the contact as good as possible on the rotors. In order to fit the caliper on your original chassis, D2 Racing provides caliper brackets to position the calipers with your new braking system, making the perfect set up for your vehicle brake system. Calipers with dust cover: FIVE years limited warranty Calipers without dust cover: TWO years limited warranty (HOLLOW RACING & 8POT) Please ensure the brake kits fit your vehicle, in particular in relation to wheel clearance, prior to ordering. MacG Racing are not responsible for fitment issues of brake kits ordered. Fitting and suspension setup also available, for information contact us prior to order. Disc Diameter/Minimum Wheel Diameter Guide 286mm Disc – 15 inch wheel 304mm Disc – 16 inch wheel 330mm Disc – 17 inch wheel 356mm Disc – 18 inch wheel 380mm Disc – 19 inch wheel 400mm Disc – 20 inch wheel 421mm Disc – 21 inch wheel The caliper options are explained below Hollow calipers – These are forged monoblock aluminium calipers which are then CNC machined to reduce the weight and improve thermal efficiency over standard monoblock calipers, as used on high end race cars, to reduce brake temperatures. The discs are a two piece design with aluminium centre bell for reduced unsprung weight and better handling, as well as better thermal performance. Hollow Racing calipers – These are forged aluminium monoblock calipers with high levels of CNC machining for optimised weight reduction whilst maintaining incredible stiffness for the ultimate pedal feel and brake temperature reduction. They also feature high temperature seals and a specially constructed piston to reduce heat transfer into the fluid. Recommended for race and track use. Kits come with two brake calipers, two brake discs, street brake pads, stainless steel brake lines and associated mounting hardware. Race pads and custom colour calipers are available on all options including polished silver, gold and titanium. Please inquire for pricing and availability. Rear brake kits are also available for most applications, and are designed to work in conjunction with the front brake kits.
