If you're looking to give your Mustang a serious boost, the ACT Sport/Race Sprung 6 Pad Kit (FM13-SPG6) is where it's at. This kit comes with a sport pressure plate that’s a solid upgrade from stock. What makes it stand out is ACT's unique diaphragm design, which cranks up the clamp load while keeping deflection at bay. This means not only better performance but also a longer clutch life. Each diaphragm goes through a four-stage heat-treating process, which really ramps up the performance you can expect.

The pressure plates are crafted with precision cover stampings, ensuring they’re rigid and consistent—no flimsy parts here. Now, let’s talk about the 6-pad, spring-centered race disc. It's built to handle some serious abuse. The spring-center construction helps dampen torsional vibrations, so you won’t be dealing with failure when things get rough. Plus, the spring retainers are designed with wraparound windows and thicker stampings, which means they provide better support and reduce stress concentrations. This all translates to a setup that’s as tough as it is reliable.

Engagement with this disc is definitely on the harsher side, but that’s what you want for quicker shifts. If you're pushing higher horsepower, this 6-pad setup is a must; it absorbs more heat and keeps everything running smoothly. Just a heads up, though—it’s not for the faint of heart. The pedal effort is light to moderate, but the aggressive engagement might give you a bit of gear rattle, especially if you're pushing your car hard.

Installation is straightforward—you can find the instructions here. Just remember, if you're installing this on an OE flywheel, you’ll need to use the conversion dowels included with the pressure plate.

Here’s a quick rundown of the specs:

• Clutch Disc Diameter: 11 in (280 mm)
• Disc Material: Ceramic
• Input Spline Quantity: 23
• Input Shaft Diameter: 1 in
• Torque Capacity: 645 ft/lbs (that’s a 0.55 increase over OE)
• Weight: 28.9 lbs

This kit is perfect for anyone looking to take their Ford Mustang (2010-2022, including the Boss 302 and GT models) to the next level, whether you’re on the street or the track. Just remember, it’s designed for high horsepower use, so if you’re serious about performance, this is definitely worth considering.
