XClutch 9" Twin Disc Clutch Kit – Toyota GR Supra (A90/A91, B58)

OVERVIEW

This is XClutch's complete GR Supra program: a 9 inch twin-disc kit for the manual-transmission B58 cars, offered with sprung organic or sprung ceramic friction discs. Both use sprung hubs rather than the rigid hubs of XClutch's BMW race kits, which is what keeps a twin-disc clutch usable on a car that still gets driven on the road.

XClutch rates the sprung organic discs to approximately 740 lb-ft. Both versions replace the factory dual-mass flywheel with a chromoly performance unit and ship complete. Choose the friction material at checkout.

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.
