Description:

The T1RR-N01 race twin disc kit is tailored for the serious enthusiast who demands a direct bolt-in kit without any 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 provide 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 trouble-free use. 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 fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.
