930 Lightweight Clutch Adapter Kit

930 Lightweight Clutch Adapter Kit

  • $420.00


This adapter set enables the use of several lightweight, "lower profile" clutch pressure plates to be used on the Porsche 930 cars equipped with the 930, 4-Speed transaxles. When applied, the reduction of rotational mass and increased clamp load provide improved acceleration and handling characteristics.  These components are specially designed to install without modification, onto specific, higher performance, lightweight clutch pressure plates.

The Porsche 930, 4-Speed Transaxle Clutch System - Model Years: 1978 to 1988


The 930 transaxles found on the road going models were originally equipped with a rubber center hub clutch disc.  This feature reduced oscillation and engine harmonics for smoother street driving. The rubber hub feature required that deeper bell housing and pressure plate cover be used.  This deeper offset resulted in increased rotational mass reducing engine acceleration performance.

The "Lower Profile" & Sprung Hub Disc - Model Years: 1976 to 1977

The Porsche 911 Turbo Carrera 1976-1977, 3.0L models were equipped with lower profile pressure plates and spring center clutch discs.  These parts represent the base type of lower profile clutch systems and the sprung hub discs which are adaptable to the later model Turbos. These pressure plates are adaptable to the later models but usually do not offer adequate clamping force. We recommend and utilize the appropriate higher clamp-load ZF Sachs parts.

Included Adapter Parts:

 Starter Ring Gear Extension Adapter
The lightweight aluminum ring gear extension is designed to provide proper offsetting of the original equipment starter ring gear.  This part utilizes the original starter ring gear and mounting bolt hardware.  This part is 3D designed and CNC machined from aluminum alloy.  Suitable for street or motorsport use.

Release Bearing Extension Adapter
This part Installs into the original equipment release bearing assembly providing proper offsetting of the release bearing fork. No modifications or welding is required as the original fork assembly is simply replaced with this unit and secured with a snap ring. This part is 3D designed and CNC machined billet 304 Stainless Steel alloy. Suitable for street or motorsport use.

Sport / Lightweight Pressure Plate Options:
We prefer to use Genuine ZF Sachs components for this adapter kit. ZF Sachs offers several original equipment applications as well as SRE (Sachs Race Engineering) Performance & Racing clutch systems.
Proper part application and disc thickness is important. Please contact us with any questions or for a current estimate.
