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 one-piece discs and aluminium 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 calipers with opposed pistons which, depending on the car model and in increasing order of performance, may be composite, monoblock or even billet monoblock components, combined with cross-drilled or slotted one-piece 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 also available as monoblock parts machined from a single billet of cast aluminium, which ensure outstanding rigidity and minimised deformation. The discs supplied in the kit are one-piece, featuring 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, TÜV/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. 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, 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.

C3 Carbon Ferrari F12 Carbon Fiber Engine Bay Panels When you open the hood of your F12, you see a beautiful 6.2L Ferrari V12 surrounded by dull-black plastic trim. Replace that trim with C3's autoclaved, pre-impregnated (pre-preg) dry 3k carbon fiber engine bay trim. Fit and finish are as perfect as the factory carbon pieces, bringsing the beauty of carbon fiber to your engine bay. C3 has matched the OEM Ferrari 1x1 weave for an original Ferrari appearance. Easy installation makes this a must-have for any F12 Berlinetta owner.

Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts. Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past. C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time. Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.

FAQs: Acura NSX Front Rotors (Girodisc A1-174) Do these fit NSX models with carbon-ceramic front brakes? Yes. They fit both iron and carbon-ceramic applications, but carbon-ceramic cars must switch to the D1405 pad shape on the front calipers. Are any caliper spacers or brackets required? No spacers or brackets are required for installation with the factory calipers. Will these change pedal feel or ABS behavior? No. Rotor dimensions and effective radius are engineered to maintain factory bias and ABS operation while improving thermal capacity and weight. Are they noisy like some floating race rotors? The floating system uses spring washers to minimize rattle at low temperatures while still allowing thermal growth under heavy use. How do I service them later? When the friction rings wear out, you can replace just the iron rings and reuse the aluminum hats and hardware per manufacturer guidelines. Fitment and ordering Acura NSX front axle.
