Description:

The T1R-S05 Mod-Twin 225 HD Sprung Race Kit is designed to facilitate aggressive launches and smoother shifting in high-powered AWD vehicles. This kit combines twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a modular design. Each diaphragm spring undergoes an exclusive four-stage heat-treating process, ensuring a consistent light pedal feel. Puck-style friction plates with high-quality ceramic friction materials deliver a high friction coefficient, superior heat capacity, and long clutch life.

These friction plates uniformly transfer torque to a Mono-Drive sprung hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration. The kit includes 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). Mod-Twin clutches are fully rebuildable, and most components can be ordered separately.

Description Highlights:

  • Feel: Predictable aggressive engagement, light pedal effort, quick shifting, possible start-off judder 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-term performance and survival under demanding conditions
  • Quality: Delivers maximum performance and high heat tolerance through robust design, strategic features, choice materials, and close tolerances
  • Recommended Use: Drag, Road, or Rally Racing
  • ACT Difference: Applying tactical engineering to the MOD-TWIN, ACT presents unique solutions to common trade-offs found on twin-disc clutches, resulting in an ultra-durable, customer-serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced, and SFI certified

Good watch but misadvertised with wrong color
Color: Black, Style: AE-1000W-1AVDF
So far I really like this watch but you get a different watch color than pictured. The watch is the AE-1000W-1AVDF which shows silver/grey and black, with a blue world map. You don't get that as the 1AVDF model is an all black watch with a grey world map. The watch is just as nice but not what was shown and sold as, so BEWARE.

Great Watch For the Money
Color: Black/Black, Style: AE1000W-1BVCF
I have been purchasing Casio watch products for over 25 years now. Their watches are low cost and nicely designed. I was not let down when I received this watch and all for 18 dollars. The watch is nice looking, has mostly usable features which fulfills its purpose. For a watch that costs under 20 dollars this is a great knock-around piece that can be worn in any setting. Whether hiking/climbing in the woods, fixing the car, swimming or just plain rough housing with my kids, having a low cost and functional watch that fits all my needs really makes this product a great buy. This Casio comes with several functions: 1) You can track up to 4 different time zones. Since I do a fair amount of business travel (about 1x a month), I am constantly in different time zones. Now I can set them easily. 2) The watch has a manual DST setting which I don't mind. It's literally a push of a button. 3) It is water resistant to 10 Bar. This means swimmers, surfers, etc... can use this watch with confidence. 4) It comes with a typical alarm. I always make sure I know how to turn this off, because you know somehow some 2 or 3 year old will get it and find a way to turn on the alarm so that it wakes you and 0200 in the morning. 5) Stop watch. Not much to say here. I use it for running/walking Cons: A couple of oddball design features that are difficult to see. 1) The upper right hand circle is actually a visual of an analogue watch, so that if you look at another time zone besides the one that you set for your home city, you can get a quick view of the time. Not so easy to see. 2) The time zone characterization is also difficult to see and not so sure it is necessary, since the back of the directions lists out the cities you can use to select the proper time zones. So this may not be a "smart" watch which seems to be very popular these days, but I will say the price makes it very worth while. If you need a knock-around that looks nice and has the core functions you need, I think you will be very satisfied with this product. You know... maybe some things don't need to be smart. Enjoy!

It is mini computer for such a low price. My favorite. Just go for it, you will be amazed!
Color: Black, Style: AE-1000W-1AVDF
I would say this is a mini computer and I keep wondering how could they put these many functions inside this small watch and offering it for 15 dollars.I'm blown away by this wonderful product and this is my favorite watch all the time and I rarely wear my other watches. Isn't this amazing that it got the time for close to 50 cities and I can select 4 of them in T1(Home City), T2, T3 and T4 to easily flip through using the bottom right button. This functionality helped me a lot during my 2 international trips through multiple transits. Before the departure I select all the Cities that I'm transiting through so that I can easily flip to that time zone when I land in that airport and I do not need to rely on airport clock or internet to know the time and calculating the time left for catching my connecting flight. I love this watch especially for this functionality. While scrolling through the time zones for selection the tiny world map in the watch will blink the specific geographical area for that time zone. The capabilities of this watch does not end here, It has lot more to offer. We can program 5 daily or one time alarms into this tiny piece. Stopwatch, Counter, 12 or 24 hour time format, Day light saving ON or OFF which simplifies the time setting when the DST switches. We can set it to signal a beep for every hour. There is digitally displayed manual clock at the top right corner which will display your home country time stored in the T1 timezone. When I go on an international trip, I flip the digital display to local time(T2-T4) and will refer the home city time(T1) in the manual clock. The watch is really durable, light weight, stylish, sporty, water proof, 10 years battery life and comes with a detailed instruction for setting up each and every functionality of this watch.What more can I expect for a 15 dollar watch. My impression to buy this watch happened after seeing one my friends wearing it. I bought one for me and 3 more for giving it as gift. My friend lost it twice and bought the same watch 3rd time which proves how much he also likes it. The last thing that I want to say is, I don't like the fancy brands which charge their customers just for the sake of their brand name or fancy packaging and offer noting more than a normal brand offers. I always prefer quality over show off so I picked this Casio watch. I really appreciate that CASIO believed in quality and functionality and not on fancy packaging. I feel really bad that I'm writing this review after 1.5 years of my purchase and I should have done it long back. I highly recommend this watch for everyone and I'm sure you will never be disappointed.
