XClutch Stage 2 Ceramic Race Clutch & Flywheel (8-Bolt) – BMW 135i / 335i (N54/N55)

OVERVIEW

The Stage 2R ceramic kit is a single-disc, race-only clutch. Available for a wide variety of vehicles, the Stage 2R provides higher torque and heat capacity than the equivalent Stage 2 kits.

This version is built for the 8-bolt crankshaft N54 and is supplied as a complete package with a chromoly performance flywheel, release bearing, pilot bushing and alignment tool. XClutch rates it at up to 670 ft-lb of torque.

TECH RESOURCES

Additional Parts Required

• None. XClutch supplies the chromoly flywheel, release bearing, pilot bushing, bolts, alignment tool and spline grease in the kit.
• Break-in is required. XClutch specifies driving the vehicle gently for the first 1,000 km (roughly 620 miles), avoiding aggressive launches; low-rpm engagements bed the friction material in properly.
• XClutch recommends inspecting the concentric slave cylinder while the transmission is out and replacing it if worn, since the labor is already committed.
• Professional installation; transmission removal is required. This is a race-only clutch and will feel harsher than a street disc.
