Spec 03-10 Mazdaspeed3 2.3L Stage 2+ Clutch Kit (Non Self-Ratcheting & MUST be used w/ FW SZ03A-2)


SPEC’s Stage 2+ features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. The 2+ offers the drivability and engagement quality of Stage 2, but with a 15-20% higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Stage 2+ is suggested for highly modified but daily driven MS3’s that will see some track time.

Important Note: These kits are a SPEC proprietary non self-ratcheting design and must be used with a SPEC billet flywheel SZ03A-2, these will not work with any other flywheel! Advantages of these units over a factory based self-ratcheting clutch upgrade are: improved pedal feel, higher clamp load options, higher rpm capability, race-proven reliability. Installation is direct bolt-in with no other modifications necessary. If you are looking to reuse your stock or any other flywheel, see SPEC’s self-racheting clutches
