Race Stage 3 Toyota 1UZ 3UZ - 6-speed manual BMW M57n GS6-53DZ HGD JGA - 184mm 7.25" (S)

PMC Motorsport Race Stage 3 – Clutch Kit Toyota Lexus V8 UZ 1UZ 3UZ – 6-Speed Manual BMW M57N ZF GS6-53DZ HGD JGA E60 525d 530d / HGA E46 330d – Ø184 mm / 7.25" STEP – Tilton OT-II Triple disc – max. 1300 Nm / 958.8 lb⋅ft

The PMC Motorsport Race Stage 3 kit allows mating the Toyota Lexus V8 UZ 1UZ 3UZ engine to the 6-speed manual ZF GS6-53DZ HGD / JGA / HGA gearbox found in BMW M57N / M57N2 diesel applications (E60 525d / 530d, E46 330d). The kit includes an aluminum gearbox adapter plate, a PMC Motorsport Ultralight Race flywheel, and a competition Tilton triple-disc clutch assembly – featuring a Tilton OT-II Cerametallic 7.25" 66-003 HGG pressure plate and three Tilton 64185-4-VTV-55 sintered clutch discs – rated to handle up to 1300 Nm (958.8 lb⋅ft).

Building a drift, time attack, or road racing vehicle powered by a heavily turbocharged or supercharged Toyota Lexus V8 UZ 1UZ 3UZ engine and need a durable 6-speed GS6-53DZ BMW gearbox paired with an ultra-light clutch capable of withstanding immense torque? The Race Stage 3 kit is engineered specifically for professional motorsport applications.

The aluminum gearbox adapter plate (thickness 20 mm / 0.78") is designed to simplify gearbox installation as much as possible, avoiding radical procedures such as cutting off the entire bellhousing – only preparing a clearance pocket for the starter motor is required.

The PMC Motorsport Ultralight Race flywheel is CNC-machined from aluminum, features a replaceable steel friction plate, and comes equipped with an input shaft pilot bearing. Each flywheel is inspected and dynamically balanced prior to dispatch. It is designed for high-performance 184 mm (7.25") STEP-type clutches, and the kit includes a matched Tilton OT-II Cerametallic 7.25" 66-003 HGG pressure plate and three Tilton 64185-4-VTV-55 sintered discs with a 32.5x35-26N spline for the GS6-53DZ gearbox. The compact clutch diameter and ultra-low rotating mass deliver lightning-fast throttle response.

PMC Motorsport parts represent precision engineering and top-tier manufacturing quality. Our design process based on 3D scanning and CMM measuring arm verification guarantees a perfect fit. Modern CNC machining ensures flawless concentric alignment between engine and transmission, which is critical for drivetrain durability.

Additional Information

Installation Instructions

Flywheel installation requires the factory automatic transmission flexplate/ring gear Toyota OE 32101-50010 and the 4.5 mm spacer positioned between the engine block and flexplate, Toyota OE 32116-50010 (not included in the kit). A factory Toyota UZ (OE) starter motor must be used with this adapter plate. The adapter plate thickness is 20 mm / 0.78".

The flywheel bolts to the crankshaft using the supplied bolts torqued to 72 Nm / 53.1 lb⋅ft with medium/high strength threadlocker, and the Tilton pressure plate secures with the provided pressure plate bolts. When installing a 184 mm (7.25") clutch, the gearbox input shaft guide tube must be shortened and the release bearing set to the appropriate position – as illustrated in the technical diagrams below. The HGA gearbox (E46 330d) is installed according to the M57 pattern, and HGD / JGA gearboxes follow the M57N pattern.

Frequently Asked Questions

Which engines are compatible with this kit?

It fits Toyota / Lexus V8 UZ family engines: 1UZ-FE and 3UZ-FE.

Which gearboxes are compatible with this kit?

It is compatible with 6-speed manual ZF GS6-53DZ gearboxes from BMW M57N / M57N2 diesel applications: versions HGD (THGD) and JGA (TJGA) – E60 525d / 530d – as well as HGA (THGA) – E46 330d.

Do I need to cut the gearbox bellhousing?

No. The adapter is specifically designed to eliminate bellhousing cutting – only a starter clearance opening must be prepared.

Which additional parts must be purchased for installation?

You will need the factory Toyota UZ automatic transmission flexplate/ring gear (OE 32101-50010) and one 4.5 mm spacer washer between engine block and flexplate (Toyota OE 32116-50010). Additionally, a clutch release bearing, clutch fork, and clutch slave cylinder dedicated to your specific gearbox are required. These parts are not included in the kit.

Which starter motor should be used?

You must use an original Toyota UZ (OE) starter motor. The starter motor is not included in the kit.

Are gearbox modifications required?

Yes. When using a 184 mm (7.25") clutch, the gearbox input shaft guide tube must be shortened and the release bearing set to the proper position. Detailed steps are shown in the technical diagrams in the "Installation Instructions" section.

Which clutch is included in the kit?

A competition 184 mm (7.25") STEP-type Tilton triple-disc clutch: a Tilton OT-II Cerametallic Pressure Plate 7.25" 66-003 HGG and three Tilton 64185-4-VTV-55 sintered clutch discs with a 32.5x35-26N spline (26 teeth) for the ZF GS6-53DZ gearbox. This clutch assembly features non-self-adjusting operation.

What torque capacity does the Race Stage 3 kit handle?

The maximum rated torque capacity of the kit is 1300 Nm (958.8 lb⋅ft).

What is included in the kit?

Aluminum gearbox adapter plate, adapter mounting bolts, custom PMC Motorsport Ultralight Race flywheel with replaceable friction surface, crankshaft bolts, pressure plate mounting bolts, Tilton OT-II Cerametallic 7.25" 66-003 HGG pressure plate, and three Tilton 64185-4-VTV-55 sintered clutch discs.

Is this kit suitable for a daily-driven car?

No. The Race Stage 3 kit with a competition Tilton sintered clutch is strictly intended for professional motorsport. For daily-driven street applications, we recommend our kits with Sachs clutches (240 mm single-disc or 215 mm twin-disc setups).

Can I purchase only the adapter plate or individual components?

Yes. Every component of our kits can be purchased separately – including the adapter plate alone or with the Ultralight Race flywheel for 7.25" STEP clutches.

Does the price include customs duties for orders outside the EU?

No. Product prices and shipping charges do not include customs duties, import tariffs, or local clearance charges applicable in the destination country.

Can I order with 0% VAT?

Yes, for B2B customers outside Poland with an active EU VAT number (validated in VIES) or for orders exported outside the European Union.

Are the included instructions sufficient for completing the installation?

The manual covers physically mating the engine to the transmission outside the chassis. Depending on the car, custom modifications may be needed: engine mounts, crossmembers, firewall clearance, transmission tunnel adjustments, and driveshaft length. Professional installation is recommended.

Please note that a lightweight rigid flywheel provides uncompromising throttle response by eliminating factory dual-mass damping elements. This yields a direct mechanical connection, which may naturally increase gearbox rollover noise at idle. This is an expected characteristic in performance vehicles equipped with rigid flywheels.
