Stage 6 Clutch Kit w/ Ironman Sintered Iron Disc

The ClutchMax Stage 6 Clutch Kit and Performance Chromoly Flywheel Bundle Set is engineered for demanding driving conditions, offering a significant upgrade for performance enthusiasts. The included Performance Chromoly Flywheel is crafted from 4140 Chromoly forged steel, precision CNC machined, and dynamically balanced to 15,000 RPM, providing a 45% weight reduction for an optimal balance between daily driving and performance. The Pressure Plate is constructed from Ductile/ Nodular Cast Iron to ensure maximum strength and superior wear resistance. The Diaphragm springs are made from 51CrV4 steel, subjected to a multi-stage heat-treating process to guarantee uncompromising performance and longevity. The clutch disc utilizes Ironman sintered iron with a chromoly solid hub, delivering absolute maximum holding power and extended clutch life. This kit has a torque capacity of 478 lb-ft and a horsepower rating of 529 HP. A recommended break-in period of 500 miles is advised. This comprehensive bundle includes the performance flywheel, an HD pressure plate, a Stage 6 Sintered Iron 6-Puck Rigid Disc, release bearing, pilot bearing, flywheel mounting bolts, clutch alignment tool, and a clutch installation guide. It is crucial that the clutch and flywheel are used together as a set, without reusing any existing components. This clutch kit is specifically designed to fit various BMW E46, E39, E36, and E85/E86 models from 1999 to 2003, including the 323i, 323Ci, 325i, 325Ci, 325Xi, 328i, 328Ci, 330i, 330Ci, 330Xi, 525i, 528i, 530i, Z3, and Z4. Specific fitments require 2.5L, 2.8L, or 3.0L 6-cylinder engines and, for certain 330 models, a 5-speed transmission. Compatibility also depends on door configuration (2-door vs. 4-door) and production dates, with specific notes for vehicles produced up to September 2003 (325 models) or March 2003 (330 models), and October 2003 for the Z4 2.5L.
