The disc engagement is harsher, but shifting is faster. The race disc features top grade rivets to securely fasten the part together. The rivet design and materials are carefully selected for maximum strength. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.\n4 Pad Rigid Race Disc\nAggressive engagement, quickest shifts, increased gear rattle; Premium ceramic friction materials provide moderate wear rates and high heat tolerance, rigid design may increase spline wear; Lightweight rigid design, chromoly hub is heat-treated for strength and durability; Recommended for race use only; High burst strength and holds 28% more torque than typical organic materials\n\u003cul\u003e\n  \u003cli\u003e\"Excellence in Performance\", backed by the best one-year warranty in the industry!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe ACT 4200005 4-Pad Rigid Race Disc is engineered for competition applications requiring aggressive clutch engagement, rapid shifting, and high torque capacity. Its four-pad rigid design uses premium ceramic friction materials that provide excellent heat tolerance and moderate wear rates under demanding driving conditions. The rigid construction delivers direct power transfer, though it may increase gear rattle and spline wear compared with a sprung-disc design.\u003c\/p\u003e\u003cp\u003eA lightweight chromoly hub is heat-treated to improve strength and durability, while carefully selected rivets provide high burst strength and securely retain the disc assembly. ACT states that this disc can hold up to 28% more torque than typical organic friction materials, making it well suited to race vehicles and smaller clutch disc applications. The aggressive engagement characteristics are intended for drivers who prioritize performance and fast shifts over street comfort.\u003c\/p\u003e\u003cp\u003eThe ACT 4200005 is recommended for race use only and may not be suitable for daily-driven vehicles because of its harsh engagement and increased drivetrain noise. This automotive clutch disc is designed for select 1990-1993 Mazda Miata applications; verify the vehicle configuration and clutch system before installation. ACT supports its performance products with a one-year warranty and its commitment to performance engineering.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications \u0026amp; Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: ACT 4200005\u003c\/li\u003e\n\u003cli\u003eBrand: ACT\u003c\/li\u003e\n\u003cli\u003eProduct Type: 4-pad rigid race disc\u003c\/li\u003e\n\u003cli\u003eFriction Material: Premium ceramic\u003c\/li\u003e\n\u003cli\u003eDisc Design: Lightweight rigid construction\u003c\/li\u003e\n\u003cli\u003eHub Material: Heat-treated chromoly\u003c\/li\u003e\n\u003cli\u003ePerformance Rating: Holds up to 28% more torque than typical organic materials\u003c\/li\u003e\n\u003cli\u003eRecommended Application: Race use only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne ACT 4200005 4-pad rigid race disc\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits select 1990-1993 Mazda Miata applications.
