OEM expected clutch life? only13800 miles

SATX370Z

Hey all. Well i think i may need a new clutch soon already. car has 13800 miles and a few mods but the car has been tracked at the drag strip one time and is pushed hard on the street. i have tried searching for an expected clutch life for our cars but have not had any luck getting a good answer. im sure i have accelerated my clutchs wear though. im looking at doing a clutch/flywheel combo all at once and am on a budget. i ran a 6 puck clutch and flywheel combo from Z1 motorsports in my 06 350z and loved it. does anyone know if running a 6 puck sprung clutch in our cars is comparable to what it was like in the 350z? this is my daily driver as was my 350z but like i said i loved it. when i drive my z now i feel like it slips slightly when getting into high rpm under WOT but only every so often. i have had slipping clutches before in other cars so i am familiar with the feel. however i dont ever smell the clutch like its burning up. has anyone else had clutch failure at so few miles? sorry for the long paragraph. thanks for reading!
