Brembo Rear 380x28 Rotors + Four Piston (M3 E90, E92, E93)

Brembo 380x28 Two-Piece Iron Rotors and Four-Piston Calipers FITS (REAR): BMW M3 Coupe (E92) 2007-2013 BMW M3 Convertible (E93) 2007-2013 BMW M3 Sedan (E90) 2008-2013 For Drivers Who Demand the Utmost From Their Car Designed and tested specifically for track-day enthusiasts and drivers who demand the utmost performance from their cars, these kits offer superlative performance for both everyday driving and demanding track-day sessions. Brembo kits consist of cross-drilled or slotted, ventilated two-piece discs and aluminium monobloc calipers with four pistons; a complete set of high performance pads; metal-braided hoses; and high quality hardware. Solutions and Technologies Born on the Race Track Braking systems consisting of motorsports-derived components offering levels of technology and performance without par on the market today and embodying the purest expression of Brembo's state-of-the-art technology. The kit consists of aluminium monobloc (one-piece) calipers with opposed pistons combined with cross-drilled or slotted two-piece floating oversized discs. Brembo kits combine the best solutions available to offer the perfect solution for the individual characteristics of each model. The heart of the kit consists of aluminium calipers. These are monobloc parts machined from a single billet of cast aluminium, ensuring outstanding rigidity and minimized deformation. The discs supplied in the kit, which are floating two-piece design, feature an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%. Cross-drilled and slotted finishes are designed and executed with meticulous precision. These holes or slots in the braking surface help dissipate heat and eliminate brake dust and gases. A set of high-performance brake pads with specific friction materials for each application, T√úV/DOT homologated metal-braided hoses, an adapter and high-quality fastener hardware complete the kit. More Braking Torque and Thermal Capacity on Track Using radial-mounted fixed calipers together with oversized discs gives the system greater braking torque and superior thermal capacity. The result is a braking action that is noticeably more immediate and decisive even in normal road usage, and is extraordinarily powerful and consistent under the repeated loads of track use. Fixed calipers improve the durability and efficiency of the system: the opposed multiple pistons act on the pads with more precision, due to the smaller piston diameter and the reduced pressure exerted on each individual piston, while the greater overall surface area between the pads and pistons results in more uniform friction surface wear. The superlative stiffness of the calipers and the metal braided hoses reduce brake fluid absorption. The result is improved, more stable brake pedal pressure, making it possible to modulate braking force more precisely and enhancing pedal feel. Featuring a hat in aluminium alloy, the oversized floating disc system reduces unsprung mass (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float. This characteristic, together with the greater dimensions of the braking rotor surface, improves the dispersion of the heat generated by the repeated, intense thermal stress that the discs are subjected to, for consistent braking performance and pedal feel even after numerous laps on the track. Eye-Catching and Unique Looks With a combination of painted calipers (available in red, yellow, black or silver) flaunting the Brembo logo, and slotted or cross-drilled discs, the Gran Turismo kit gives an unmistakably sporty, eye-catching look to the car, offering that extra special touch for drivers who want their vehicle to stand out from the crowd. Catering to the more discerning driver is the GT-R line of kits. These offer even more performance and consist of billet-monoblock calipers, slotted discs in diameters up to 405 mm and special high performance pads.
