this is an article I found while looking into transmission problems it mentions this bit about the racing clutch on the street.
Like cardshark said it will bit instantly and not as smooth as a stock one.

Another point of early transmission failure is the wrong choice of clutch for the application. This usually begins with the idea that installing a performance clutch will improve the vehicle performance. There are a great variety of clutch sets available on the performance side and many car owners do not understand what they were designed for when making a purchase. The correct setup will definitely improve performance over stock, and the wrong clutch will make driving a misery and create big time trans failure. We see all the time that an owner has opted to install a full racing clutch in a street driven vehicle. In many cases the friction material is way too aggressive for use in traffic , which shock loads the gear train causing broken inputs, clusters and speed gears, as well as possible damage to the differential and drive shaft. It is very important to match the clutch to the vehicle usage. A car that is only track driven can handle more aggressive setups, while a car that is a daily driver with occasional trips to the drag strip will be no fun to drive in traffic with a clutch that acts like an on/off switch. This happens very frequently in light trucks, where somebody's cousin tells him that the way to go is a ceramic button type of disc instead of the factory woven friction material. They both will work, but the aggressive grab of the button clutch puts the trans at risk as well as making his girlfriend puke sick. Again if the clutch is not releasing properly, the button type or dual disc clutches will increase the failures dramatically. One other issue that results in very rapid transmission damage similar to overly aggressive clutch friction material is the choice of the clutch disc itself. The vehicle was manufactured with a clutch disc that had a sprung hub. This allows the disc as it engages the flywheel and pressure plate to turn against the springs in the hub absorbing the shock load and removing harmonic vibrations that cause gear rattle and other noise issues due to engine harmonic vibrations. In the quest for better performance the owner may substitute a solid or unsprung clutch disc, eliminating the cushion effects engineered into the OEM product. An unsprung clutch hub should only be used in a purpose built race vehicle where the owner intends to freshen up the clutch and trans every race or two. The unsprung hub will definitely shorten the component life of the transmission.
