The best drivetrain upgrades for your 2013-2021 Subaru BRZ start with the parts that put power to the ground reliably — an Exedy OEM-spec flywheel for a fresh clutch job, Perrin driveshaft carrier bushings to cut driveline slop, and a quality shift knob for more precise shifts. These are the bolt-on pieces that make the FA20 drivetrain feel tighter without a rebuild.
Drivetrain mods bridge the engine and the wheels: clutches, flywheels, driveshaft components, bushings, and shifters. On the BRZ platform — the rear-wheel-drive chassis shared with the FR-S and 86 — small upgrades here pay off in feel. A fresh OEM-spec flywheel restores clean clutch engagement during a clutch replacement, while firmer carrier bushings reduce the thud and delay felt on throttle transitions.
The 2013-2021 BRZ drivetrain collection at JDMuscle includes flywheels like the Exedy OEM Flywheel TYF001, which is listed for the 13-17 BRZ plus FR-S and 86 applications; driveline pieces like the Perrin Driveshaft Carrier Bushings; and shifters such as the Mishimoto Shift Knob. Shop related parts in Clutch, Performance Flywheels, Shifters And Bushings, and Driveshaft Shop Driveshafts. Popular brands here include Mishimoto, Perrin, Exedy, Verus, NRG, and Torque Solution.

Do I need a tune after installing a flywheel?
No. An OEM-spec flywheel is a mechanical replacement part that requires no ECU changes — just a proper clutch break-in afterward.
Will the Exedy TYF001 fit my BRZ?
It is listed for the 13-17 BRZ as well as FR-S and 86 applications. Confirm your year and trim against the product fitment list before ordering.
Do carrier bushings add vibration?
Firmer carrier bushings can add a small amount of driveline noise, but most drivers notice improved throttle response and less driveline slop instead.
How hard is a flywheel or clutch install?
Clutch and flywheel work requires dropping the transmission, so it is a full-day job for a home mechanic or a few shop hours — budget for fresh hardware and a break-in period.
