Exedy Lightweight Flywheels

Exedy lightweight flywheels combine low weight, low inertia, and high thermal capacity. They're designed for light to moderately tuned racing cars for drag racing, autocross, and rally events, as well as street usage. The flywheels are made from solid one-piece billet chromoly steel or chromoly steel forgings. These replacements are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the airflow, which improves the cooling of the clutch. The ring gear teeth are integrated onto the flywheel, unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and has the possibility of separating from the flywheel due to the different expansion coefficients of aluminum and steel. Newly available are lightweight, solid replacements for vehicles fitted with OE dual mass flywheels. Exedy lightweight flywheels have passed engineering tests to 15,000-18,000 rpm. They're guaranteed not to fail to the said RPM, and are all SFI approved. * Material: All Exedu lightweight flywheels are made from either forged or billet chromoly steel. Chromoly is an abbreviation for "chromium-molybdenum steel" due to its property of incorporating alloy elements chromium and molybdenum. Thanks to this combination of materials, chromoly has an excellent strength to weight ratio and is considerably stronger and harder than standard 1020 steel or other aluminum flywheels on the market. * SFI certification: All Exedy Stage 1 Organic, Stage 2 Ceremetallic and Lightweight Flywheels carry SFI 1.1 Certification. Which means, when you buy these products, you can be confident they're certified for use in competitive motorsports. * Resurfacing Exedy flywheels: Resurfacing your Exedy lightweight flywheel during a clutch service is an ideal way to extend the life of your clutch and flywheel. Thanks to the nature and design of the Exedy flywheels, no special steps or tools are needed to perform the service. All you should do is follow the OEM service specifications to return your Exedy flywheel to "like new" condition.

XClutch Stage 1 Clutch Kits

XClutch Stage 1 clutch kits offer a variety of performance upgrades for both street and track applications. They are designed in-house and normally utilize a single plate organic, ceramic, or carbon friction disc along with an upgraded factory-style pressure plate. XClutch kits utilize a similar mechanism to the factory clutch, making them ideal enhancements for most vehicles with low to mid-level performance modifications. Stage 1 clutch kits are available in three distinct performance clutch packages—sprung, rigid solid, and steel-backed organic. Features and benefits of each: * 1A sprung organic—this range has been specifically designed for street vehicles that have minor engine and general performance modifications. These kits offer a sprung organic friction disc that allows for great drivability, while offering improved clamping force through the use of a performance pressure plate. * 1G rigid solid organic—with a rigid center version of the organic disc, this range is ideal for street vehicles and light track use. These kits are often available with a lightweight alloy pressure plate and performance flywheel. * 1T steel-backed organic--this range offers a higher burst strength by bonding the organic friction material directly to a steel backing plate. These kits are ideal for high performance vehicles used on the street with occasional track use.
