PRODUCT DESCRIPTION
High Performance Twin Disc Clutch Kit for Toyota 1JZ and 2JZ Engines and BMW ZF M50/M52/M54 5-Speed Gearboxes - Stage 1 FTWL
Kit includes single twin disc clutch, release bearing, and all necessary bolts.
100% CNC Machined Parts - Made in EU
Precision machining and alignment ensure perfect fitment.
Single-piece flywheel: approximately 8.2 kg.
Rotating assembly weight approximately 14.9 kg. (Flywheel + intermediate plate + pressure plate)
240 mm lightweight, custom-made clutch discs: steel base + LUK 8090s friction pads
Sachs 3082, 311, and 341 pressure plate without SAC system
Heat-resistant CNC machined clutch disc spacer/intermediate plate
The clutch assemblies are fully balanced (end-to-end): flywheel, intermediate plate, and pressure plate, according to class G6.3 and up to 8500 rpm. Each clutch assembly is delivered with a unique balancing protocol.
Thanks to the superior design and quality of the intermediate plate, it does not produce noise when pressing the clutch pedal. It also does not stick when hot, as it does not contact the flywheel.
Works and engages smoothly like an OEM clutch assembly.
Comes with a 19mm thick aluminum adapter plate with all necessary bolts. The adapter requires a DENSO 228000 series starter, which does not have an aluminum cover over the starter gear.
Compatible with TOYOTA 1JZ and 2JZ engines with the following transmissions:
ZF/GETRAG M50, M52, M54 5-speed gearboxes and E36 M3 6-speed - 23x29-10N spline shaft
Not compatible with M54B30 6-speed gearbox (modified version)
Not compatible with ZF N47M, M57, and E46 M3 5-speed gearboxes (28x35-10N spline shaft)
Ideal for high-power turbocharged engines
Supports up to ~800-1000 Nm of torque in conventional vehicles
For entry-level drifting, up to ~800 Nm, we recommend maintaining a torque reserve. If the clutch is frequently damaged, we strongly recommend choosing the Stage 2 or 4 version with sintered clutch discs.
Professional installation and break-in (at least 1000 km or 5000 gear changes) are required.
Our flywheels always include the starter ring gear (monobloc solution).
All used parts are standard, allowing for quick and economical renewal of the complete assembly.
Every product has undergone endurance testing, because only power and quality matter.
