Description:

The T1S-S07 Mod-Twin 225 HD Rigid Street Kit is designed to offer easy pedal feel, smooth but positive engagement, and quick shifting for high-powered AWD vehicles. It achieves this through a modular design that combines twice the organic friction surfaces with a rigid Mono-Drive hub assembly.

Each diaphragm spring undergoes an exclusive four-stage heat-treating process to ensure durability and consistent pedal feel. The steel-backed friction plates, featuring high-quality organic friction materials, deliver stable friction coefficient, good heat capacity, and long clutch life. These friction plates uniformly transfer torque to a Mono-Drive chrome-moly hub, heat-treated for strength and durability, extending input shaft life with one continuous spline.

The lightweight, rigid design allows for quicker shifts and trouble-free service. The kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, floater, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable, and most components can be ordered separately.

Features:

  • Feel: Soft progressive engagement, light pedal effort, smooth shifting, with mild to moderate transmission gear noise.
  • Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure long-life performance under demanding conditions.
  • Quality: Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances.
  • Recommended Use: Street or Street/Strip.
  • ACT Difference: Utilizes tactical engineering to address common tradeoffs found in twin-disc clutches, resulting in an ultra-durable, customer-serviceable, long-lasting clutch with very high torque capacity. All clutches are 100% clamp load tested, balanced, and SFI certified.

Vehicle Fitment:

  • Application: Engine
    • Various Subaru Impreza WRX STI models from 2004 to 2021 with 2.5 H4 GAS FI 2458cc engines, DOHC configuration, and Turbocharged.

Great lotion for very dry skin
Style: Updated Formula
I had a laser done on my face and the products they gave me weren't working. This came highly recommended so I gave it a try. I'm very glad I did! It moisturized my face really well without appearing greasy. I used the rest when my face got dry from winter (in th midwest). Felt very rich and smooth. Medium thickness.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!
