Description:

The T1SS-S01 Mod-Twin 225 HD Sprung Street Kit is specifically designed for high-powered AWD street cars, offering a blend of uncompromised pedal feel, durability, engagement quality, and high torque capacity. This kit achieves its performance through a modular design that combines twice the organic friction surfaces with an ultra-durable spring center Mono-Drive hub.

Each diaphragm spring undergoes an exclusive four-stage heat-treating process to ensure a consistent light pedal feel. The steel-backed friction plates, featuring high-quality organic friction materials, deliver a stable friction coefficient, good heat capacity, and long clutch life. These friction plates uniformly transfer torque to the Mono-Drive sprung hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration.

Included in this kit are a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (if needed). The Mod-Twin clutches are fully rebuildable, and most components can be ordered separately.

Features:

  • Feel: Soft progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise.
  • Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure long life and performance under demanding conditions.
  • Quality: Delivers maximum performance and high heat tolerance through 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 models from 2005 to 2023 with different engine specifications.

Great value watch with all the basic functions.
This is a solid watch for the money. I think if you are looking for a training watch that doesn't break the bank, this is a good option. I looked at a ton of options, and I know there are some even cheaper entry level options, but this Ironman was a little bit of a step up in appearance and quality. To me it's worth it to get this over something in that $20 to $30 range. The Ironman was more stylish and less bulky than a lot of those options. This watch has a nice sized face that makes it easy to see without being so large that it's too much. There are some of these entry level sports/military watches that are just enormous. I'm not a huge guy so this was a much better option. One thing I am really liking is how flexible the strap is. The material has a nice give to it making it a very comfortable watch to wear. I've had some watches in the past where the bands were just too stiff and made the watch very uncomfortable. It's easy to understand and operate. I didn't even read the manual and had everything figured out after 5 or so minutes. Unless you are really going to step up and get a GPS smart watch in the $200 and up range, this watch is a great option.

Great watch for healthcare workers
This is a great watch that I use for my nursing clinical rotations at hospitals. It has been washed and disinfected many times and it still looks new. I can read the time without my glasses I wear for astigmatism. The light is good for nighttime or darkened rooms. I think the alarm and hourly chime are harsh sounding, but they serve their purpose if needed (The beep of a Casio digital watch is preferred, for a frame of reference).

used solely as start watch for yacht racing: interface is good (lacks sync feature). Great value
on foredeck of a sailboat, lines and sails love to snag on stuff, especially wrist watches. Have had three torn from my wrist in 18 months. Two went overboard. I even tried to purchase super-strong spring-bars (pins that secure the band), but it was torn off again. PRO: great (intuitive, quick) interface for setting the countdown starting time, and option to repeat or count up. easy to read display CON: No sync feature: in countdown timer mode, would allow adjusting the running countdown to the nearest minute. Delay in switching modes: had left it in time-of-day mode and heard a starting signal, immediately switched to Timer mode and pressed start button, but it did not start the timer. On switching modes, it takes nearly a second for Timer mode to be operational, so need to wait until display comes on before trying to use it. Time-of-day is not visible in Timer Mode, if it was, previous issue would rarely occur. No Power down feature: my previous watch had an option to shut off the LCD display (and any audible alarms). Since I only use the watch about 100 hours (1%) of the year, this greatly extended the battery life. All that said, the dedicated sailing watches all cost two to ten times as much with the lower cost options having poor reviews on quality. For now, I'll buy these (Timex Ironman Essential 30) and just expect to loose one on average once a year.

Great watch - Nice large display!!
After my old Timex Ironman finally died after 21 years of reliable service (may it rest in peace after 4 replacement bands and 5 replacement batteries!!), I decided Timex deserved another sale from me! So I went surfing on the Timex website. So many Timex Ironman watches to choose from! But this one stood out for two reasons. 1) It has a nice simple design without a lot of "noise". 2) A nice large readable display. So I took the plunge! Indeed, Timex has definitely improved on their Ironman watches in the last 21 years. Most notably, the Indiglo light has greatly improved. It used to just light up the background. Now, it brightly lights up the actual digits which makes it undeniably readable without any eye strain. Another great improvement are in the set features. While the older models could only be set forward (in other words, if you went past your set point, you would need to go all the way around), this model lets you set forward and backward (so if you go too far, you can step back without going around). I don't understand one of the reviewers saying that the watch is too small. The face is quite large. The band may seem narrow in proportion to the watch face, but not excessively so. The band is 19mm wide and fits me just fine. Highly recommended!!
