If you're looking to take your Subaru to the next level, the Advanced Clutch 4 Pad Sprung Race Disc 4240518 might just be what you need. This isn't your average clutch disc; it's designed for those who crave performance. With its four-pad, spring-centered design, it’s built from high-quality ceramic friction materials that deliver a harsher engagement but allow for quicker shifts. Trust me, once you feel the difference, you won’t want to go back.

One of the standout features of this race disc is the heavy-duty torsional dampening springs. They’re stronger than what you typically find in standard setups, and they’re perfectly sized for your application. This means you’re not just getting a clutch disc; you’re getting a piece of gear that’s engineered to handle the demands of racing. Plus, the heat-treated spring steel drive plate adds an extra layer of durability, making this disc a solid choice for smaller engines that need a reliable performance boost.

Now, I won’t sugarcoat it—this disc is meant for race use only. If you’re pushing your Subaru to its limits, you want something that can keep up. The aggressive engagement and quick shifts can lead to a bit of gear rattle, but that’s just part of the thrill. You’ll appreciate the premium ceramic materials that offer moderate wear rates and can handle high heat, so you won’t have to worry about it giving out on you mid-race.

When it comes to specs, this disc measures in at a diameter of 9.4 inches (or 240 mm), with a spline quantity of 24. It’s got a splined bore diameter of 1 inch and weighs in at a solid 3.4 lbs. What’s more, it boasts an impressive SFI rating of 1.1, which speaks to its reliability and performance under pressure. And if you’re curious about fitment, it works with a range of Subaru models, including the Baja (2006), Forester (2006-2008), Legacy (2005-2012), Outback (2005-2009), STI (2004-2021), and WRX (2006-2024).

So, if you're ready to enhance your ride and experience the kind of performance that makes every shift feel like a dream, consider the Advanced Clutch 4 Pad Sprung Race Disc. It's not just a part; it's a game changer.
