Alright, gearheads, let’s talk about the ACT HD/Race Rigid 4 Pad Kit TC5-HDR4. If you're looking to beef up your clutch game, this kit is where it's at. ACT’s Heavy Duty pressure plate is a solid choice, featuring a unique diaphragm design that cranks up the clamp load while keeping deflection low. This means you get a clutch that lasts longer and can handle the heat from your spirited driving.
One of the standout features is the four-stage heat-treating process that each diaphragm goes through. Seriously, it’s like giving your clutch a performance-enhancing spa day. The pressure plates are crafted with precision cover stampings, which adds to their rigidity and consistency. You want reliability at high RPMs, and these plates deliver.
Now, let’s talk about the 4-pad rigid race discs. Made from high-quality ceramic friction materials, these discs are tough as nails. The chrome-moly hub is heat-treated, ensuring you’re not going to snap anything during those high-stress shifts. The lightweight design means quicker shifts, but be warned—engagement can be a bit harsher. If you're used to a softer ride, you might feel the difference, but trust me, it’s worth it for that speed.
This setup is particularly great for smaller engines, where the 4-pad design shines. You’ll get a light to moderate pedal effort, but don’t expect a buttery smooth engagement. It’s aggressive, and you’ll definitely hear some gear rattle, but that’s just part of the charm when you’re racing.
