XClutch 11-13 BMW 335is Base 3.0L Stage 2R Extra HD Sprung Ceramic Clutch (6 Bolt/PB in Input Shaft)

If you're looking to upgrade the clutch on your 2009-2016 BMW Z4, the XClutch Stage 2R Extra Heavy Duty Sprung Ceramic Clutch Kit is a solid option. This kit is designed for vehicles that need to handle more torque and heat than a stock clutch can manage, making it a popular choice for track use and demanding driving conditions. It's a single-disc setup featuring a sprung ceramic friction disc, which helps absorb some of the shock and vibration associated with aggressive engagement.

XClutch has put a lot of thought into the design of this kit. They've analyzed the pivot point and diaphragm to ensure a positive pedal feel, even with the increased clamping force needed to hold more power. The Stage 2R ceramic material is specifically chosen for its high torque capacity and ability to withstand higher temperatures, which is crucial when you're pushing your car hard. This kit includes a chromoly flywheel, a high-performance pressure plate, a release bearing, a pilot bearing, and an alignment tool, so you have most of what you need for the installation.

Keep in mind that this Stage 2R kit is considered a race-only clutch. While it offers significant improvements in torque holding and heat management over the Stage 2 versions, it's built for performance applications. It's a well-built component that aims to provide a good balance between driveability and the performance you need when you're on the track or dealing with higher horsepower setups.
