Spec 91-00 Toyota Supra (1JZGTE & R154) Organic Trim Super Twin Disc Clutch Kit

This SPEC Super Twin Clutch Kit, Organic Trim, is designed for street, drag, and road racing applications in cars with extreme horsepower and torque (700-1500 ft/lbs). It offers near-stock drivability, extended life expectancy, and a straightforward, direct bolt-in installation without the need for shimming or complex setup. The unit is constructed entirely from billet aircraft-grade aluminum and high-carbon billet steel, precision-milled to an industry-leading .001 inch for optimal balance and actuation, ensuring smooth and quiet operation. Friction is provided by dampened, full-faced carbon graphite discs. The kit includes a new master cylinder, billet slave cylinder with stainless lines and fittings, a flywheel, and track-spec hardware. These units are rebuildable by either SPEC or the end user, with replacement components and rebuild services readily available.
