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.

South Bend Clutch Stage 3 Endurance clutch kits are recommended for single mass flywheel (SMF) when original design is DMF (dual mass) to achieve optimal performance. These kits use the same race-engineered SFI-approved pressure plates as Stage 3 Daily Driver packages. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar® friction material is used for its unique friction compounds applied with high-energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. These Stage 3 Endurance clutch kits are recommended for applications such as rally, endurance race, club sport, autocross, performance street and daily driving. Order the kit you need.

ACT Mod-Twin 225 heavy-duty twin-disc street clutch kits are designed to tackle aggressive launches and rapid shifting of high powered AWD's—by combining twice the organic friction surfaces with a no-nonsense solid mono-drive hub in a completely modular design. Each diaphragm spring endures an exclusive 4-stage heat treating process to provide a more consistent light pedal feel. The puck-style friction plates, with high-quality organic materials, deliver high friction coefficient, superior heat capacity, and long clutch life. These friction plates uniformly transfer torque to a mono-drive chromoly hub, which is heat-treated for strength and durability, extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. Clutch kits are available in different styles and other options for fitment on countless vehicles from the early 2000s and up. Features and benefits: * Recommended for drag, road, or rally racing use * Predictable aggressive engagement, light pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise * Forged aluminum cover, mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions * Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances * 100 percent clamp load tested, balanced, and SFI certified Kit contents: * Forged aluminum pressure-plate cover * CNC-machined and dynamically balanced flywheel * Diaphragm spring and face * Puck-style organic friction plates * Available with sprung or unsprung mono-drive hub assembly * Floater * Patented mono-Loc collar * Release bearing * Alignment tool and pilot bearing (if needed) Note: Mod-Twin clutches are fully rebuildable and most components can also be ordered separately, if you do not need to purchase complete kit.

Tilton OT-Series Cerametallic clutch kits are primarily designed for racing applications. They utilize a unique blend of ceramic and metallic materials to create superior 4-paddle discs that allow for some clutch modulation. Because cerametallic discs are thicker than sintered metallic discs, their increased mass provides higher heat capacity. Plus, the engagement characteristics of cerametallic clutches are smoother than sintered metallic clutches. These features have made Tilton cerametallic clutches popular in rally, hill climb, club-racing, off-road, and extreme street/strip applications. Features include: * Open, one-piece clutch cover design; provides lower operating temperatures, higher strength and minimized deflection for quick shifting * Several spring rate options; provide a wide range of torque capacities and release loads to tune the clutch for the application * Chrome vanadium diaphragm springs and engineered pressure plate geometry; provide high clamp load-to-wear ratio, low release loads, and quick shifting * High-strength steel pressure and floater plates * 0.283 in. thick friction discs; provide excellent wear resistance and withstand elevated temperatures * Hardened steel thrust buttons; provide a smooth and durable surface for pressure and floater plates * Dynamic spin balanced * Individually inspected for proper assembly and balance

SPEC Stage 4 clutch kits are solid hub versions of their Stage 3 clutches. Each hub is solid with eight rivets and the assembly is heat-treated for strength and durability. They are available in a 3, 4, and 6-puck configurations. Use a 3-puck for the lightest option or a 6-puck for the smoothest engagement. The 4-puck kit is a good compromise for both. Street-drivable in 6-puck configuration, but not street friendly due to the rigid hub. Additional features of SPEC Stage 4 clutch kits: * High-clamp pressure plate * Carbon-graphite friction material * High-torque solid hub and disc assembly * Bearing and tool kit included * Great for road racing, rally, drag racing, drifting, and pulling
