R6 Solid Hub 6-Pad Disc:
Recommended for road racing and drag racing. Race geared disc that would be a little too harsh on the street but perfect for race cars or non-daily driven track cars. This disc is a popular choice for stock based road racing cars.

Benefits are:
increased torque capacity, faster shifts, reduced inertia, very good durability but shortened spline life, absorbs more heat than a 4-pad disc, sharper engagement than sprung hub disc but smoother than 4-pad disc.
