question.. Im new to owning a viper and have never performed clutch work before. I have 2 2002 vipers (red er ) Im not racing or anything to extreme... just fun zippy trail riding on nice groomed trails..

What clutch update would you all suggest to update the clutch to get just a tad bit more snappy (AKA: throttle response) coming out of a turn on the trail? Also what are the key areas to monitor for maintenance and how do you know when to maintenance..
