G6 Spring Centered 6-Pad Disc:
Recommended for road racing. Track geared disc that will hold up to track abuse and be tame enough for the street, perfect for non-daily driver lightweight autocross and time trial cars that are driven to the track. Benefits are: increased torque capacity and spline life over a solid disc, quiet operation, reduced driveline shock, and sharper engagement than stock type disc but smoother engagement than G4 Disc.
