If you're looking to upgrade your clutch setup, the ACT TM1-HDSS kit is definitely worth your attention. I’ve had my fair share of experiences with clutches, and let me tell you, this one stands out. It combines ACT's heavy-duty pressure plate with a performance street disc, which is a solid choice for anyone who wants a balance of durability and everyday drivability.
What I really appreciate about this kit is the heavy-duty pressure plate. It’s designed with a unique diaphragm that ramps up the clamp load, keeping deflection to a minimum. This means that not only will you get a firmer grip during shifts, but it also extends the life of your clutch. Each diaphragm goes through a four-stage heat-treating process, which is something you don’t typically see in most kits. This extra step really pays off in terms of performance.
The performance street disc is another highlight. Made with premium organic materials that have a good amount of copper, it’s built for better heat transfer. You can feel the difference when you’re pushing your car a bit harder. Plus, the steel-backed lining adds a layer of durability that’s crucial for high-stress situations. And if you’re like me and enjoy a bit of spirited driving, the reduced marcel in the disc means quicker shifts, which is a game changer.
Installation is straightforward, but if you need a hand, ACT provides detailed instructions that you can check out here. Just a heads up, this kit doesn’t come with a clutch master cylinder or flywheel, but it does include grease and an alignment tool, which is a nice touch.
Now, let’s talk specs. The clutch disc diameter is 9.3 inches (or 236 mm), and it’s designed with a sprung solid disc type. With an input spline quantity of 21 and a shaft diameter of 1.125 inches, it fits snugly into your setup. The torque capacity is rated at 390 ft/lbs, which is a solid bump over stock. If you’re running a Toyota MR2 from 1991 to 1995, this kit is specifically designed for you, making it a perfect match for your ride.
In short, if you want a clutch that feels good on the street and can handle some track time without breaking a sweat, the ACT TM1-HDSS kit is a fantastic option. It strikes that sweet spot between performance and reliability, and honestly, you can’t go wrong with it.
