Stage 4 clutch kits are designed for heavily modified street and track vehicles with significant power upgrades. The included lightened flywheel reduces engine inertia for quicker acceleration and more responsive rev-matching. This kit provides substantially increased holding capacity compared to OEM clutches, making it suitable for turbocharged, supercharged, or high-compression naturally aspirated builds. Note that Stage 4 clutches typically have a firmer pedal feel and more aggressive engagement characteristics than stock clutches.
