If you're looking to elevate your ride's performance, the MB1-SPG4 ACT Sport/Race Sprung 4 Pad Kit might just be what you need. This kit is not just another upgrade; it’s a game changer. It features a sport pressure plate that’s been designed specifically to boost clamp load while minimizing deflection. What does that mean for you? Simply put, it maximizes clutch life and keeps your shifts smooth and reliable, even when you're pushing the limits.

One of the standout features here is the four-stage heat-treating process that every diaphragm goes through. This isn’t just marketing fluff; it really does enhance performance. The pressure plates are crafted with precision cover stampings, ensuring they’re rigid and consistent, which is crucial when you’re on the road or track.

Now, let’s talk about the 4-pad spring-centered race disc. It's built tough with a spring-center construction that helps dampen those torsional vibrations, so you get a quieter ride. And trust me, it can handle the heat—perfect for those high-stress situations. The engagement might be a bit harsher compared to stock setups, but that’s what makes shifting faster and more responsive. Plus, it’s particularly well-suited for smaller engine setups, making it a versatile option for a range of vehicles.

Installation is straightforward, and if you need a hand, you can find the instructions here.

What else can you expect? The pedal effort is light to moderate, and while the engagement is aggressive, it’s balanced out with a bit of OE to mild gear rattle. The friction life is moderate but extended thanks to that exclusive diaphragm design. It’s engineered with select ceramic friction materials, which means it can take on high heat and still perform like a champ.

This kit is recommended for high horsepower street or race applications, and it’s been 100% clamp load tested and dynamically balanced to ensure reliability at high RPMs. Here are some key specs to consider:

• Clutch Disc Diameter: 8.8 in (224 mm)
• Input Spline Quantity: 20
• Torque Capacity: 385 ft/lbs (that’s a 51% increase over OE)
• Product Weight: 11.8 lbs

Just a heads up, this kit doesn’t come with a clutch master cylinder, flywheel, or pilot bearing, but it does include grease and an alignment tool to make your install smoother. It’s compatible with a range of vehicles like the Chrysler Sebring (2003-2004), Dodge Stealth (1991-1996), and Mitsubishi Eclipse (1990-2005), among others.

So, if you’re ready to take your driving experience up a notch, give the MB1-SPG4 kit a shot. It’s built for those who want to feel the difference every time they hit the gas.
