If you're pushing the limits with your AWD street machine, the Advanced Clutch Mod-Twin 225 HD Sprung Street Kit is where you want to be. This isn’t just another clutch; it’s a serious upgrade for those high-powered rides that demand more from their components. With double the organic friction surfaces and a tough Mono-Drive hub, this kit is built to handle some serious torque—up to 700 ft/lbs, to be exact. That’s enough to keep your power on the pavement without worrying about slippage.

Now, let’s talk about what really sets this clutch apart. The diaphragm spring goes through a four-stage heat treatment process, which means you get a consistent, light pedal feel every time you engage. The steel-backed friction plates are made with high-quality organic materials, ensuring you have a stable friction coefficient and solid heat capacity. This means you can expect a longer clutch life, even under the stress of spirited driving or at the track.

Installation? It's straightforward. The kit comes with everything you need, including a CNC-machined flywheel and a release bearing. Plus, you get an alignment tool to make your life easier. Just so you know, it’s designed to fit specific models like the Subaru Impreza (2004-2014), Subaru STI (2004-2021), and Subaru WRX (2004-2020). This is not a one-size-fits-all deal; it’s engineered for precise fitment.

Here’s a quick rundown of the features:

• Soft progressive engagement for smooth shifting, with just the right amount of OE noise
• Forged aluminum cover and premium friction materials that can take a beating
• Perfect for street or street/strip setups
• Rebuildable design—most parts can be ordered separately, so you’re not stuck replacing the whole kit
• All components are clamp load tested, balanced, and SFI certified for peace of mind

And for those of you who care about the nitty-gritty, here are the specs:

• Clutch Disc Diameter: 8.8 in (225 mm)
• Input Spline Quantity: 24
• Input Shaft Diameter: 1 in
• Product Weight: 28.1 lbs

This clutch is about more than just numbers; it’s about performance you can feel. So if you’re ready to take your driving experience to the next level, the Mod-Twin 225 HD is the way to go. Just remember, it’s built for those who really know their stuff and want a clutch that can keep up with their passion.
