Sonnax shift improver performance packs combine innovative heavy-duty performance calibration for firmer shifts under load without sacrificing low-speed drivability. The precision components in these kits upgrade your transmission for maximum achievement and durability by recalibrating pressures, recalibrating shift accumulation, and including improved parts for areas that commonly wear. They are suitable for any heavy-duty application and are a critical foundation for other upgrades when modifying the transmission for high performance use. Sonnax shift improver performance packs additional facts and features: * Shorter shifts, which get progressively firmer with load * Faster pressure increase and higher overall pressure for greater clutch/band holding power * Three ultra-reliable, patented, billet pinless accumulator pistons * Unique 1-2 accumulator spring combination for shifts with character * Improved high rpm pressure * Third accumulator valve gets the 2-3 right the first time, every time * Consistent results, no guessing on calibration * Prevents worn accumulators and separator plate * Optional TCC on-off conversion prevents excess TCC pressure

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.
