The OS Giken STR Series dampened twin-plate clutch with soft diaphragm is specified for Toyota JZX90 and JZX100 platforms and brings a multi-plate dampened option to those chassis. The twin-plate layout plus a soft diaphragm favors smoother engagement for street-focused builds while offering increased friction area over a single-plate setup, making it suitable for JZX90/100 owners upgrading clutch capacity.
