If you're looking to take your 2018-2023 Ford Mustang GT to the next level, the Advanced Clutch Mod-Twin 10.5 HD Rigid Street Kit is the real deal. This isn't just another clutch; it’s designed for those who want that sweet balance of easy pedal feel and quick, precise shifts without the fuss. Imagine having twice the organic friction surfaces working for you, all paired with a solid Mono-Drive hub that’s built to last. It’s modular too, which means you can easily swap parts if needed.

Now, let’s talk about that pedal feel. Each diaphragm spring goes through a four-stage heat treatment process, so you get a light and consistent feel every time you stomp on the pedal. The steel-backed friction plates use high-quality organic materials that not only improve heat capacity but also extend the life of the clutch. We’re talking about a setup that transfers torque smoothly to a heat-treated Chromoly hub, which helps keep your input shaft happy with its continuous spline design.

This kit doesn’t just come with the clutch; it’s got everything you need to get rolling: a CNC-machined and dynamically balanced flywheel, a pressure plate cover, a diaphragm spring, puck-style ceramic friction plates, and an alignment tool. Trust me, you’ll appreciate the ease of installation. And if you ever need to rebuild it, no worries—Mod-Twin clutches are fully rebuildable, and you can grab replacement discs separately.
