Description: The AI4-HDG4 kit from ACT features their popular Heavy Duty pressure plate combined with a 4-pad spring-centered race disc, delivering high-performance capabilities suited for high horsepower street or race use:

Heavy Duty Pressure Plate:

  • Utilizes ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life.
  • Endures a four-stage heat-treating process for unparalleled performance and reliability.
  • Precision cover stampings provide rigidity and consistency for smooth engagement and shifting.

4-Pad Spring-Centered Race Disc:

  • Features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions.
  • ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability.
  • Offers harsher engagement but ensures faster shifting, making it well-suited for smaller disc sizes in smaller engines.

Smooth Engagement, Enhanced Reliability:

  • Provides a light to moderate pedal effort with aggressive engagement, suitable for high horsepower street or race use.
  • OE to mild gear rattle may be experienced due to the spring-centered design, but it enhances performance characteristics.

Vehicle Fitment:

  • Compatible with various models including the 1994-2001 Acura Integra GS-R, LS, RS, Special Edition, Type R, 1994-2001 Honda Civic del Sol VTEC, 1998-2001 Honda CR-V EX, LX, and 1999-2000 Honda Civic Si.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.
