New to the forum with a Clutch Question

[1sicrunner]

I am building a car for Best is the Desert Pro 1000 Class RZR XP4-900 based on a 2013 model, pretty much everything on the unit has been either reworked or replaced. The engine was built by Kroyer and made over 120Hp on the Dyno. I am running 30" tires and the builder expects the car to weigh in around 1800-1850 wet and ready. The area that appears to be the weak spot with a lot of the UTV's that do not finish races is the belt /clutch and sometimes the Transmission or front diff. My question is who are the go to guys in the UTV business for high performance clutches and clutch tuning and is anyone reworking the transmissions for race applications? I expect have to the car completed and tested in mid June with the first race being V2R in August but could use some direction on the clutch and trans questions. Great Forum, thanks for any help

I would say STM but I'm no Polaris expert. But the looks of the other comments I wouldn't put money on it.
