Description:

The AR1-XTR4 kit by ACT features an Xtreme pressure plate designed for the most demanding drivers. ACT Xtreme pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for unparalleled performance. Precision cover stampings ensure rigidity and consistency. ACT's 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.

  • Feel: Moderate to heavy pedal effort, aggressive engagement, increased gear rattle
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended Use: Recommended for race use only
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

No fluff to fill
Style: Medium/Firm, Size: Queen
Arrives vacuum packed; not a problem with that; however, a week after opening the pillows are still flat. I thought they might still work for my pillow shams - not what they were bought for, but they didn’t fill out the shams either. Sad as I really like Serra brand normally.

Keep their form for a bit
Style: Medium/Firm, Size: Queen
These pillows are fairly good quality, and keep their form better than what you might pick up at the end of the row at a big box store. After about a month of regular use, they've collapsed visibly from what they were on the first day, but still provide support. They are shipped flat in a container and take some time to plump up, but I didn't notice any strong odor on opening. Like most foam pillows, I expect a trip through an electric clothes dryer will probably fluff the pillows up again. I don't know what makes these "down alternative" as oppose to a regular foam-filled pillow, and there is a sharp distinction from my down pillow. Most notably, the down pillow provides much more support. There would be no mistaking one of these for a down pillow.
