For lower duty applications and on smaller discs a bolted mounting is sometimes preferred for strength and simplicity, especially for off-road applications (e.g. Rallies) where debris may clog a floating mechanism leading to run-out and disc vibration.
Stiff flat bells should be avoided with a bolted mounting.
