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.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!
