SA2025 helmets are here, and while the changes may not be groundbreaking, they represent an important evolution in motorsport safety. According to the Snell Memorial Foundation, the SA2025 standard is an evolutionary update from SA2020—not a complete overhaul. Unlike the M2025 motorcycle standard, which adds rotational impact testing, the SA2025 auto racing helmet standard does not include rotational force requirements. Key SA2025 Helmet Safety Enhancements: Increased Impact Protection: SA2025 helmets are required to handle slightly higher impact speeds and achieve lower maximum peak G-force thresholds across all head-form sizes. Global FIA Alignment: These updated requirements bring the SA2025 standard into alignment with the new FIA 8859-2024 helmet safety regulation, creating more consistency across international motorsports. In short: SA2025 helmets are designed to offer enhanced linear impact protection, making them the safest Snell-rated auto racing helmets to date. Whether you're a competitive racer or a weekend track day enthusiast, upgrading to an SA2025-certified helmet ensures compliance with future racing regulations and gives you peace of mind at speed.

C3 Carbon  Lamborghini Huracan LP610 Carbon Fiber Rear Vent Panels Beautiful carbon fiber replacement for the black plastic trim panels surrounding the Lamborghini Huracan LP610's rear engine hatch. C3's autoclaved, pre-impregnated (pre-preg) dry carbon fiber panels install simply with no modification, bringing you the most accurate, beautiful fit and finish available anywhere. C3 matches the OEM Lamborghini 2x2, 3K twill carbon weave perfectly for an original Lamborghini appearance. The spectacular look of these carbon fiber piece adds so much flair to the engine cover of Lambo's one-of-a-kind Huracán. Fitment: 2014+ Lamborghini Huracán FEATURES: Autoclaved pre-preg dry carbon fiber with 2x2, 3K Twill Weave matched to Lamborghini OEM carbon fiber Clear-coated with automotive urethane, hand polished to a mirror finish OEM-perfect fit Install easily without any modifications Digitally 3D laser scanned for guaranteed fitment Autoclave formed in billet aluminum molds at more than 100 psi and 200o F Experience the Difference of C3 Carbon Products Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. 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.

Brembo 2-Piece Rotor FAQs How long do Brembo discs last? The usable life of a brake disc is influenced by a number of factors including vehicle weight, driving style, vehicle usage, brake pad material, and many others. Therefore a blanket disc lifetime cannot be given. However, when used in the same conditions, a Brembo disc should meet or exceed the life of the disc it replaces. It is important to periodically check the disc thickness, and replace the disc if it falls below the minimum allowed thickness. How does reducing weight of the braking system benefit the vehicle? The mass of any vehicle requires energy to accelerate or decelerate. Reducing vehicle mass improves acceleration and requires less energy to be dissipated during deceleration. Rotating mass requires additional energy in order to increase or decrease its speed of rotation. Therefore, decreasing the mass of the caliper is valuable due to its contribution to total vehicle mass. Decreasing the mass of the disc has an even greater benefit due to the fact that the disc must rotate as well. Additionally, the mass of the brake system is also unsprung mass. Reducing the unsprung mass has the additional benefit of improved suspension performance, resulting in enhanced ride and handling. Should new discs and pads be bedded in? The bedding procedure is an important step when installing new rotors and pads. Correctly bedded pads form a transfer layer of material on the surface of the disc which improves overall "bite" and performance. Without proper "pre-bedding" that simulates the correct heat and torque loads seen in actual driving conditions, a pad's true potential cannot be realized. This process will also ensure that the pads will produce a rotor finish with a consistent transfer layer which prevents "judder" from occurring. The Brembo Bedding Memo should be followed when installing a new Brembo system or new discs and / or street pads. For race friction and / or track use, please contact us for detailed information regarding the appropriate bedding procedure to follow. Some of the bushings in the two-piece disc assembly seem to be loose. The two-piece disc assemblies utilize a floating disc. The mounting system of the disc is designed to allow a specific amount of float in both the radial and axial directions. Brembo has engineered special springs that are used on every other fastener in order to slightly preload the assembly. This has been done to prevent excessive noise from the system during street use, while still maintaining the benefits of a floating disc. These springs can be seen when looking at the backside of the disc. The small screws on the backside of the disc are properly torqued during assembly and utilize thread lock compound to prevent loosening. They must not be tightened further. What is the difference between the systems Brembo offers? Brembo offers different levels for different applications, and for different budgets. There are currently three performance levels within the Brembo program. The first level is the Sport system. These kits include cross-drilled or slotted discs and high performance brake pads, and are direct replacements for the OEM components. The second level, the Gran Turismo system, upgrades the entire corner brake assembly. These kits combine fixed mount, 4, 6, or 8-piston aluminum calipers equipped with high performance brake pads, one or two piece directionally vented discs, and steel-braided brake lines. For those seeking a system for exclusive or nearly exclusive track use, the Race systems offer upgrades consisting of true racing components. Why are there so many holes in a cross-drilled disc? The number of holes in a cross-drilled disc is part of the engineered system. Brembo has done extensive testing with regards to the number of holes, their size, their location and their chamfering. This attention to detail is what truly sets Brembo apart in the world of braking. The same attention to detail that is delivered to the Ferrari Formula One effort is a component of the high performance program. The number of holes in a disc is in part a function of the size of the disc and the internal venting (if it is a vented disc). Why use a two-piece "floating" disc assembly? There are several reasons that a two-piece floating disc assembly is of benefit. First, by using an aluminum bell for the hub section of the disc saves a great deal of weight. Since this is both rotating and unsprung, it benefits the acceleration, braking, and handling of the vehicle. Secondly, it is better able to handle the large temperature changes that a brake disc experiences. In a two-piece floating disc assembly, the iron disc heats up uniformly, and the controlled float which is present allows for the differential expansion of the very hot brake disc, and the relatively cool aluminum bell. This allows the disc to be used under severe conditions without having a detrimental effect. Will a Brembo brake system work with my standard master cylinder, ABS, or traction control? Brembo brake systems are designed to work with your standard master cylinder, and do not hamper the function of your ABS or traction control system. Will I experience brake noise with Brembo brakes? Brembo makes every effort to test for and eliminate abnormal brake noise from the systems we offer. There are many factors that can contribute to abnormal brake noises, and while it is unlikely that a Brembo system will create noise, the engineering and customer service departments are available to answer questions and work to solve any noise issues which may arise. Please contact us if you have additional questions or concerns. How do I properly bed my new Brembo brake rotors? It is important to follow the proper brake bedding procedure following installation. This is necessary not only for optimum performance of the system, but also to avoid onset of judder (vibration felt through brake and steering).   The discs are delivered with a thin zinc coating to prevent corrosion. Prior to beginning the bedding procedure, this plating must be removed from the braking surfaces by driving the car slowly (under 30mph) and performing very light brake applications in order to remove the plating without generating heat. With too much heat or pedal pressure, this plating can be deposited unevenly on the disc, and impregnated into the pad, further increasing the likelihood of judder development. Once a visual inspection of the braking surfaces confirms that the plating has been evenly removed, begin with the bedding procedure as specified below. Drive vehicle to a remote area and perform at least 30 brake applications of 3 second duration. Use light/medium deceleration with varying starting speeds. Leave at least ½ mile between each brake application The purpose of this procedure is to gradually increase the temperature in the components without thermal shock, and to mate the brake pad and disc friction surfaces  After the repeated stops, drive the vehicle for several miles with little or no braking in order to adequately cool the components  The system is now ready for normal use  This entire procedure must be complete before driving the vehicle as normal. It is especially important that this process is completed before any extended same-speed driving is done (i.e. freeway travel). Failure to follow these instructions greatly increases the likelihood of judder development
