[1]The resurgence in the popularity of manual transmissions is definitely a good thing. Late model cars are making more power and torque than ever before, but let’s face it – they’re not getting any lighter, either. Put these facts together, and you’ll know why so many people are looking for clutches that can handle the job when a supercharger, turbo kit, or nitrous gets thrown into the mix.

Advanced Clutch Technology [3] has been working hard to expand their line of twin-disc clutches to meet this demand – Once strictly a race part, these clutches have been tamed for the street without losing any of their strength. The twin friction discs mean twice as much surface area in contact, providing better wear, more heat capacity, and longer life than a comparable single disc design, and they deliver higher torque capacity without the need for insane spring pressure. That means you can get a clutch for your street/strip car that will handle pretty much anything you can hit it with, and still keep your left leg from going numb.

Shown here is ACT’s T1S-G01 clutch for late model Chevy applications, including LS1, LS2, and LS7 Corvettes and the 2010 Camaro SS. With a rated torque capacity of 850 pound-feet, believe it or not, it’s the most civilized member of the family! By selecting different friction materials and pressure plate diaphragm springs, ACT can take you to 1125 pound-feet capacity in a street-spec twin-disc clutch, 1200 in a street/race unit, and as high as 1450 for full-race applications.
