Description:

The T1RR-H03 race twin disc kits are engineered for the serious enthusiast who demands a direct bolt-in kit without additional modifications. ACT's sintered iron race discs offer the highest torque capacity among all ACT race discs and boast ultra-high heat capacity. Most kits offer pedal loads 10-20% higher than stock while increasing the clamp load by 80-90%.

Each kit includes a CNC-machined and dynamically balanced flywheel for seamless operation. Additionally, all kits undergo an exclusive four-stage heat-treating process on all diaphragms. The kit comprises a pressure plate, two discs, floater, flywheel, and alignment tool. Some kits may also include a pilot bearing and release bearing. ACT Twin disc kits meet SFI Specification 1.2.

Description Highlights:

  • Feel: Light to moderate pedal effort, predictable, quick engagement, quick throttle response, increased gear rattle
  • Life: ACT's exclusive diaphragm, hardened posts, and high heat capacity ensure long life under severe abuse, although the rigid design may increase spline wear
  • Quality: Carefully engineered, precisely assembled, accurately balanced, with a chromoly hub heat-treated for strength and durability
  • Recommended Use: Recommended for high horsepower race use only, not intended for street
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
