Toyota 86 and Subaru BRZ Clutch Upgrade: Stock vs Stage 2

Toyota 86 and Subaru BRZ Clutch Upgrade: Stock vs Stage 2

Toyota 86 and Subaru BRZ Clutch Upgrade: Stock vs Stage 2

The 86, BRZ and Scion FR-S are some of the easiest cars to modify, and the factory clutch is built for stock output. Add a header, an E85 tune or a supercharger, and the clutch starts slipping in the higher gears or after a few hard pulls. The question most owners ask is whether a stock replacement is enough or whether they should step up to a Stage 2 kit.

The whole range lives in our clutch kits collection, with matching flywheels and pressure plates.

Signs the Stock Clutch Is Done

  • Revs climb without the car accelerating, especially in fourth through sixth under load.
  • A burnt smell after hard driving or track use.
  • Engagement that creeps higher on the pedal.
  • Shudder or chatter from a glazed disc.

Stock Replacement or Stage 2?

A clutch buyer's guide from SubiMods gives a practical way to choose. It says the factory clutch is designed for stock power with smooth engagement and efficiency in mind, and lays out suggested levels by torque:

  • Stock to about 180 ft-lb (intake, exhaust, tune on a naturally aspirated car): Stage 1 organic.
  • 180 to 250 ft-lb (header, full exhaust, E85 tune): Stage 1 to Stage 2.
  • 250 to 350 ft-lb (supercharger or small turbo): Stage 2 to Stage 3.
  • 350 to 450 ft-lb (built motor, bigger turbo): Stage 3 to Stage 4.

The same guide describes the trade-off: higher stages mean firmer pedal effort, more aggressive engagement and more drivetrain noise.

The Exedy kits in our store follow the same ladder in the maker's own words. Stage 1 is an organic clutch with higher clamp load for modified engines, described as ideal for street and light-horsepower track use, with drivability similar to stock and slightly higher pedal effort thanks to spring-center dampers. Stage 2 uses cerametallic friction material built for high-power modified engines; Exedy says its thick disc has better heat capacity and that the three- and four-puck designs usually have less inertia than a stock disc, for street, rally and track use.

ACT Street and Race Options

ACT's HD/Performance Street Sprung kit fits the 2013-2016 FR-S, 2013-2020 BRZ and 2017-2020 Toyota 86 according to a retailer listing, and its disc is a premium organic material with high copper content and a steel-backed lining. A listing for the SB8-HDSS version of the kit gives 270 ft-lb (61% over OE) with light to moderate pedal effort and smooth positive engagement. Its race counterpart in rigid form is listed at 349 ft-lb (107% over OE) with aggressive engagement and increased gear rattle, and is recommended for race use only. The same fitment for ACT's HD-M Race Rigid 6 Pad kit and HD/Race Sprung 6 Pad kit suits track cars, but check each listing title for the exact model years.

Which One Should You Buy?

  • Unmodified car, worn clutch: a stock-style replacement such as the Exedy OE kit or the XClutch standard replacement kit.
  • Bolt-ons and a tune, daily driven: Stage 1 organic, or the ACT street sprung kit.
  • Supercharged or heavy track use: Stage 2, expecting a firmer pedal.

Flywheel and Replace-Together List

Resurface or replace the flywheel with every clutch, and note that some kits require a specific flywheel: the Clutch Masters FX350 and FX400 kits for this car call out a Clutch Masters flywheel in their titles, so read each title. See our guide on when to replace the flywheel during a clutch job. Also replace the release bearing and pilot bearing where the kit includes them, any weeping rear main or input seal, and a soft clutch slave or master cylinder (clutch hydraulics). If you are also a Subaru WRX owner, our WRX clutch stage guide shows the same stage ladder.

Cost and Effort

This is a transmission-out job: plan a full day with a transmission jack. Doing the flywheel, seals and hydraulics at the same time costs far less than going in twice.

Frequently Asked Questions

Do I need Stage 2 on a lightly modified 86 or BRZ?

Probably not. For an intake, exhaust and tune, a Stage 1 organic clutch is the usual recommendation and keeps stock-like drivability.

Will a Stage 2 clutch make the pedal heavy?

Yes, somewhat. Higher stages bring firmer pedal effort, more aggressive engagement and more drivetrain noise.

Is a stock replacement clutch good enough?

If the car is unmodified and the clutch is simply worn, an OE-style replacement is fine. Once you add power, step up to Stage 1 or higher.
