How Does A Clutch Work?

The clutch allows you to engage and disengage the engine from the transmission smoothly. This is accomplished through several transmission components working in unison - the clutch disc, pressure plate, and throwout bearing. When you push the clutch pedal in, the throw-out bearing releases pressure exerted by the pressure plate against the clutch disc. This causes the clutch disc, which is splined to the transmission's input shaft, to separate from the engine's flywheel. 

This separation disengages the drivetrain and allows you to shift gears. When you release the pedal, the pressure plate again squeezes the clutch disc against the flywheel to reconnect the engine and transmission. Understanding how the clutch disc, pressure plate, and throw-out bearing interact is important when it's time to choose your new performance clutch.

Why You Need An Aftermarket Subaru BRZ Clutch

The factory BRZ clutch is designed for smooth daily driving, not maximum performance. It tends to reach its limit once you start modifying the engine and increasing power levels. The OEM clutch can start to slip when adding common bolt-ons like intakes, headers, or tunes. This is where upgrading to an aftermarket performance clutch makes sense.

Quality aftermarket clutches provide increased torque capacity and durability compared to stock. This gives you confidence that all your engine's power will make it to the wheels without clutch slip. Aftermarket options also provide smoother, more precise gear shifts whether daily driving or on track.

When shopping for a new BRZ clutch, match it to your power goals. Conservative kits can handle up to 400hp which is suitable for mild street builds. On the extreme end, twin-plate racing clutches can hold over 800hp for dedicated track BRZs. Do your research to pick the right clutch so you don't leave performance on the table or overspend.

Subaru BRZ Clutch Types

When selecting an aftermarket BRZ clutch, you'll encounter some key choices that impact performance and drivability:

Single-plate clutches are the simplest upgrade from stock. They utilize a larger diameter single disc for more surface area and grip. Single plates offer affordable performance gains perfect for mildly tuned BRZs.

For big power, multi-plate or twin-disc clutches stack several small discs to dramatically increase holding capacity. The added surface area enables twin-plate clutches to reliably handle over 800hp in high horsepower builds.

Friction material is another important consideration. Organic materials provide smooth engagement well-suited for street driving. Ceramics offer aggressive bite ideal for dedicated track and competition BRZs.

There are many ways to go when upgrading your BRZ's clutch. Carefully consider your power goals and how you drive. A quality aftermarket clutch unlocks sharper response and optimizes performance potential. Properly matched to your build, an upgraded BRZ clutch puts the engine's power to good use and enhances the driving experience.

Factors to Consider When Choosing a Clutch

Several important factors should be factored in when you’re deciding on your BRZ performance clutch selection -

  • Driving style - Aggressive driving needs higher holding capacity. Daily drivers prioritize smooth engagement.
  • Power goals - Light tunes need less capacity than big turbo builds. Match the clutch to your mods.
  • Clutch materials - Organic for smoothness, Ceramic for track-ready bite. Impacts drivability.

By weighing these key considerations relative to how you drive and your build goals, you can select the ideal BRZ clutch upgrade.

How to Install a Clutch in a Subaru BRZ

Tools Required

  • Transmission jack
  • Impact wrench and sockets
  • Torque wrench
  • Clutch alignment tool
  • Basic mechanics toolset (wrenches, screwdrivers, pliers, etc.)
  • Specialty tools included with the clutch kit
  • Safety glasses and gloves
  • Jack and jack stands
  • Clean work rags

Safety Precautions

Proper safety precautions are critical when installing a BRZ clutch -

  • Disconnect the battery before starting work to prevent electrical issues or shock.
  • Securely jack up and support the BRZ. Use jack stands - don't rely on a jack alone.
  • Wear safety glasses and gloves throughout the process.
  • Carefully lower transmission to avoid injury or damage. Use a transmission jack.
  • Keep the workspace clean and organized to avoid losing or damaging components.
  • Consider having an experienced mechanic guide you through the process if it's your first time changing a clutch.
  • Take your time and stay focused on safely completing the job from start to finish. Rushing leads to mistakes and potential injuries.

Following safe practices and having the right tools ensures an efficient, injury-free BRZ clutch installation.

Other Subaru BRZ Supporting Modifications

Subaru BRZ Catback Exhausts

Installing a catback exhaust system is a popular supporting mod to pair with a BRZ clutch upgrade. Catbacks from brands like the Invidia, MAPerformance, and Tanabe Medalion enhance power while adding an aggressive exhaust note. By reducing restrictions, catbacks allow the FA20 engine to breathe and rev freely. Most quality options add 7-15hp through improved exhaust flow. Just ensure your new clutch is rated to handle the extra torque before pulling the trigger on a catback exhaust.

Subaru BRZ  Lightweight Flywheels

Swapping the stock dual-mass flywheel for a lightweight single-mass flywheel is a great complimentary upgrade when replacing your clutch. Lightweight flywheels remove rotational mass which allows your BRZ’s engine to rev more quickly with an improved throttle response. While ideal for dedicated track cars, lightweight flywheels can also be used by daily-driven BRZs as long as you don’t choose something that is too lightweight.

Subaru BRZ  Short Shifters

Short shifters are a simple way to make your BRZ's shifter feel more precise. Reducing the shift throw by 25-40% enhances the driving experience and makes shifting quicker on both the track and street. Brands like GKTech, IRP, and Billetworkz offer options ranging from $200-600. Short shifters pair perfectly with new clutches to optimize the feeling of fast, smooth shifts. Just be aware that added NVH is common. Adding a short shifter is an easy and effective supporting mod for your new clutch kit.
