NPC can probably answer that question for you. Honestly, they are not just trying to sell as many clutches as they can, they will help you choose the right one for your application.
It should be fine. Go the Billet flywheel as well as it directs a bit of air through the clutch as it spins. The main killer of these clutches is excessive heat, so as long as you arent riding the shit out of it, you shouldnt have an issue.
Mine is street driven and taken to the drags once in a while, my clutch was fine last time it was out of the car, no signs of any problems at all. I got it rebuilt as a preventative thing, but I dont think it was necessary at all. Had an NPC clutch for probably 6 years now.
