Performance Notes: As with all multi-disc ceramic upgrades, some increase in NVH (noise, vibration, and harshness) is a normal characteristic of this performance product and is not a defect. This kit is recommended for dedicated performance and race vehicles, and is ideally suited for use with sequential transmissions. Inspect all clutch actuation components for wear during installation.
