If you're serious about performance, the Advanced Clutch Twin Disc HD Race Kit T1R-F04 is a game changer for your Ford Mustang. This isn’t just another clutch kit; it’s a hardcore upgrade that gives you double the disc surfaces compared to standard single-disc setups. What does that mean for you? Better wear, improved heat capacity, and a lifespan that can handle the demands of serious racing.

This kit features a unique Positive Lift Floater System design, which means you get a quieter operation with zero floater rattle. No more annoying noises as you shift gears—it’s all about smooth transitions here. Plus, with the exclusive four-stage heat treating process on the diaphragms, you can trust that this clutch is built to last, even under extreme conditions.

One of the standout features is the 6-pad rigid race discs. Made from high-quality ceramic friction materials, they’re designed to withstand high temperatures without sacrificing performance. The chrome-moly hub is heat-treated, ensuring it can take a beating while keeping everything intact. And let’s not forget the lightweight, rigid design that allows for quicker shifts—perfect for those split-second decisions on the track.

Installation is straightforward, too. Each kit comes with a CNC-machined and dynamically balanced flywheel for hassle-free setup and reliable operation. You’ll get everything you need: a pressure plate, two discs, a floater, the flywheel, and an alignment tool. Some kits even throw in a pilot bearing and release bearing, depending on what you choose.
