The ACT 600230 XACT Prolite Flywheel is a lightweight, low-inertia flywheel built for the 1991-1998 Nissan Silvia's 2.0L turbo four-cylinder [JDM]. Dramatically improved engine response and acceleration come with mild-to-moderate gear rattle, a trade-off typical of lightweight race flywheels. Heat-treated forging delivers strength and toughness, and induction-hardened ring gear teeth maximize service life. The one-piece construction reduces potential failure points and provides efficient, uniform heat transfer away from the clutch disc, eliminating warped inserts or loose ring gears sometimes seen on multi-piece flywheels. The flywheel is forged, CNC-machined, and dynamically computer-balanced for smooth reliability at high RPM, and is recommended for race use.

FAQ
Will an aftermarket flywheel like this work with the stock clutch and pressure plate?
In most cases a lightweight flywheel is designed to work with the stock or a matching aftermarket clutch disc and pressure plate, but the flywheel's bolt pattern, pilot bore, and friction surface height should always be checked against the specific clutch kit being installed.
What is a "flywheel step" and does this flywheel have one?
A flywheel step is the raised friction surface machined into the flywheel face that the clutch disc rides against. The XACT Prolite's step height is machined to ACT's specification to work with ACT clutch discs sized for this application.
How much material can be removed when resurfacing this flywheel?
Up to 0.040 in (1.02mm) total can be removed during resurfacing before the flywheel should be replaced.
Does this flywheel fit all Nissan Silvia trims from 1991-1998?
It is built for the 1991-1998 Nissan Silvia K [JDM] with the 2.0L turbo four-cylinder engine. Confirm the specific chassis and engine code match before ordering.
