ACT HD/Race Sprung 4 Pad Kit Toyota Supra | Lexus SC300 1986-1998 - TS3-HDG4

If you're looking to upgrade your ride's clutch setup, the ACT TS3-HDG4 Advanced Clutch HD/Race Sprung 4 Pad Kit is worth considering. I've been using this kit for a while now, and it really makes a difference, especially if you're pushing some serious horsepower. The heart of this kit is ACT's Heavy Duty pressure plate, which is designed to handle the heat and stress of high-performance driving. I can tell you from experience that the exclusive diaphragm design does wonders—it's all about increasing clamp load while minimizing deflection. This means you get a clutch that lasts longer and performs better under pressure.

One thing that stands out is the four-stage heat-treating process that each diaphragm goes through. It really enhances performance, and I’ve noticed it holds up well even when I’m really testing the limits. The precision cover stampings provide a level of rigidity that you can feel when you're in the driver’s seat.

Now, let's talk about the 4-pad spring-centered race disc. This isn't just any disc; it's designed to dampen torsional vibrations, which makes for a quieter ride. But don't let that fool you—it's tough as nails and can take a beating. The engagement is definitely on the harsher side, but that just means quicker shifts, which is something you’ll appreciate when you’re racing or just wanting a bit more thrill on the road.

As for installation, it’s pretty straightforward. Just make sure you check out the installation instructions here to get everything right.

Here are some features that make this kit stand out:

  • Light to moderate pedal effort, but expect aggressive engagement and a bit of gear rattle.
  • Moderate friction life, thanks to that clever diaphragm design that ACT has nailed.
  • Engineered for high heat tolerance, using select ceramic friction materials for maximum performance.
  • Perfectly suited for high horsepower street or race applications.
  • Every unit is clamp load tested and dynamically balanced, ensuring smooth operation at high RPMs.

In terms of specs, here’s what you need to know:

  • Clutch Disc Diameter: 9.3 in (or 236 mm)
  • Disc Material: Ceramic
  • Input Spline Quantity: 21
  • Input Shaft Diameter: 1.125 in
  • Torque Capacity: 365 ft/lbs
  • Weight: 16.9 lbs

This kit is compatible with the Lexus SC300 (1992-1997) and Toyota Supra (1986-1998). If you're serious about performance, this clutch kit is a solid choice that won’t let you down.
