DESCRIPTION
A complete ACT stage one clutch kit (ZM2-HDSS) with organic street disc matched with ACT's own steel PRO-lite 9 pound flywheel. A great combination for autocross, track, and use with boost up to 12 psi. XACT flywheels are certified by ACT to meet SFI Spec. 1.1. This makes XACT Flywheels legal for competition when SFI Spec. 1.1 is required or recommended. XACT flywheels come complete with official SFI sticker and serial number as required for certification.
This is the 1.8 size but because you are matching 1.8 flywheel here with 1.8 clutch size...it can be installed into all 1990 to 2005 Miatas.
