Description

[1]The balance between treading force and crimping

Even though the pressure has been increased to achieve overwhelmingly high capacity, the clutch pedal has a solid feel. It doesn’t make you worry about its weight.

The LA Clutch series introduces a purpose-engineered high-performance clutch kit. It is specifically developed to unlock and manage elevated power levels for the Honda S2000 (AP1/AP2). Designed with an estimated capacity of 280kW (380PS) and an allowable torque of 450N・m (46kgf・m), this kit delivers overwhelming holding capability from a single-disc clutch system.

This provides a decisive advantage for high-powered applications. By masterfully balancing extreme torque capacity with reduced weight, it enhances performance without compromising drivability. Furthermore, it effectively doubles driving pleasure even in naturally aspirated vehicles.

Product Highlights

⚙️ Overwhelming Torque Capacity for High-Powered Applications
Engineered to support significant power upgrades, this clutch boasts an estimated tolerance of 280kW and 450N・m of torque. This provides a substantial safety margin and reliable performance for forced induction builds, high-compression NA setups, or spirited track use. Consequently, it eliminates clutch slippage as a performance limitation.

🔄 Refined Pedal Feel & Balanced Operability
Despite the significantly increased clamping force required for its high capacity, the clutch pedal delivers a firm, communicative feel without excessive weight. This careful tuning ensures the clutch remains comfortable in daily driving.

Also, it stays manageable in stop-and-go traffic. It bridges the gap between race-capable performance and street-friendly usability.

🔥 Advanced φ215 “MG Composite Disc” Technology
The core of the system is the innovative “MG Composite Disc,” constructed by forming and weaving metal fibers with glass fiber. This proprietary material achieves an ideal balance of friction coefficient, heat resistance, strength, and wear resistance. The disc offers smooth, gentle engagement for normal starts. It also delivers immediate, positive lockup during aggressive circuit driving without slippage. Its low-inertia design reduces load on synchronizers for quicker, crisper gear changes.

🏗️ Reliable Strap Drive Mechanism & Lightweight Construction
The clutch cover utilizes a robust strap drive mechanism, ensuring consistent and reliable clutch actuation. Strategic weight reduction across all components—including a lightweight, drilled flywheel—minimizes rotational mass. This results in sharper engine response and improved acceleration. Additionally, it eliminates jerky low-RPM behavior. Meanwhile, the reduced kit weight (as low as 64% of AP2 OEM) decreases drivetrain inertia.

🛡️ Enhanced Refinement & Drivetrain Protection
An integrated disc damper system effectively reduces transmission gear rattle and unpleasant NVH (Noise, Vibration, Harshness), increasing cabin comfort. Furthermore, this damper protects the entire drivetrain—including gears, axles, and differential. It absorbs and cushions shock torque from aggressive launches or sudden shifts.

It is engineered not just as a stronger component, but as a more intelligent and balanced system.

Focus: Achieving maximum torque capacity through advanced materials (MG Composite Disc); maintaining street civility through tuned pedal effort and damper technology; improving engine response via significant weight reduction; and ensuring long-term reliability with robust design (Strap Drive).

Installation, Usage & Compatibility Notes

🔧 Professional Installation Recommended
Proper installation and flywheel surfacing/machining are critical for optimal performance, wear, and longevity. Alignment and bolt torquing procedures must be followed precisely.

⚠️ Critical Performance & Usage Guidelines:

• Capacity Ranges: Understand the operational limits:

  • Allowable Range: Safe for regular use, including moderate slip.

  • Conditional Tolerance Range: Slippage may occur with aggressive abuse, tire kickback, or driveline distortion.

  • Exceeding Allowable Limit: Slippage will occur during high-RPM engagements.

  • Physical Limit: Clutch will slip under full-power acceleration.

• Vehicle Model Specification: Ensure correct kit selection for AP1 vs. AP2 applications, as flywheel and pedal characteristics differ.

• Break-in Period: A proper break-in procedure is essential for optimal disc mating and long-term performance.

🎯 Primary Performance & Driver Benefits:

• Unshakable Power Delivery: Confidently handles significant power upgrades without slip.

• Enhanced Driver Engagement: Communicative pedal feel and crisp engagement improve control.

• Improved Throttle Response: Reduced rotational mass yields faster engine revving and acceleration.

• Daily Driving Compatibility: Retains a manageable pedal effort and smooth low-speed operation.

• Drivetrain Longevity: Damper system protects expensive transmission and differential components.

Strategic Advantages & Technical Innovation

📈 From Bottleneck to Foundation
This clutch transforms a common power upgrade limitation into a cornerstone of the drivetrain, providing a reliable platform for current and future performance ambitions.

⚖️ The Balance of Extremes
It successfully reconciles traditionally opposed traits: extreme holding capacity with street-friendly pedal weight; aggressive lockup with smooth low-speed driveability; lightweight performance with reduced NVH.

🛠️ Complete System with Serviceability
The kit is offered as a complete, vehicle-specific solution. Furthermore, individual repair parts (cover, disc, bolt sets) are available (Code: 26999-AH003/AH004/AK004), ensuring long-term serviceability and cost-effective maintenance.

[2]  φ215 “MG composite disc” adopted

• “MG Composite Disc” is a disc that has achieved an ideal coefficient of friction, heat resistance, strength, and wear resistance by forming metal material into a fiber shape and weaving it together with glass fiber.
  
• It has a characteristic that leads to a very mild start when starting normally, but when driving on a circuit, etc., it has a characteristic that leads to a quick start without any slippage.
• Adopting a low inertia disc reduces the aggressiveness of the synchro and supports quick gear changes.

[3]Adopts strap drive mechanism

Even though the pressure has been increased to achieve overwhelmingly high capacity, the clutch pedal has a solid feel that doesn’t make you worry about its weight.

[4]sharp response

By reducing the weight appropriately for each vehicle model, we achieved sharp response and acceleration performance while eliminating the jerky feeling. The flywheel uses a lightweight drilled type to reduce inertia.

[5]Prevents abnormal noise and protects the drive system

The adoption of a disc damper reduces unpleasant gear noise from the transmission.
This part also protects the drive system by absorbing impact torque.
