AE92 OS Giken TS2A / TS2AS Twin-Plate Clutch & Flywheel | 4A-GE (1987-91 Corolla)

OS Giken TS2A / TS2AS Twin-Plate Clutch Kit with Flywheel

For 1987–1991 Toyota Corolla AE92 coupe equipped with naturally aspirated 4A-GE engines and original manual transmissions.

Overview

The OS Giken TS2 twin-plate clutch and matched flywheel is offered in standard-diaphragm TS2A and softer-diaphragm TS2AS configurations for 1988–1991 U.S.-market Toyota Corolla GT-S coupes and 1987–1991 Japanese-market Toyota Corolla Levin and Sprinter Trueno AE92 coupes with naturally aspirated 4A-GE engines and their original manual drivetrain. Japanese GTV production coverage ends in May 1989.

Both configurations use two compact 184 mm heat-treated alloy clutch discs, a stamped-steel cover and a matched flywheel. TS2A prioritizes torque capacity, while TS2AS reduces pedal effort with its softer diaphragm spring. Both are performance clutches; low-speed take-up and hill starts may be less forgiving than with an organic street clutch.

Key Features

• Two 184 mm heat-treated alloy clutch discs
• Matched flywheel included with either configuration
• Stamped-steel clutch cover
• Choice of standard or soft diaphragm spring
• Approximately 350 lb-ft torque capacity for TS2A; 300 lb-ft for TS2AS

Which Twin-Plate Clutch Should You Choose?

TS2A — Best for Greater Torque Headroom

Choose TS2A when your performance build needs its higher approximate 350 lb-ft capacity. The standard diaphragm requires more pedal effort than the TS2AS.

TS2AS — Best for Lower Pedal Effort

Choose TS2AS when reduced pedal effort matters more than maximum torque headroom. Its softer diaphragm is rated for approximately 300 lb-ft, but engagement can still feel abrupt.

Our Recommendation: Choose TS2A for additional torque headroom or TS2AS for lighter pedal effort. For a stock-power car where easy daily-driving engagement matters most, consider a correctly matched organic clutch instead.
