So currently own a 2017 m240i 6mt. I will be needing to upgrade my clutch once I go big turbo, my expectations for power will be around 650-700whp.

I have been contemplating back and fourth on what the best option would be, here are my current options.

Spec stage 3+ clutch + Clutchmasters Aluminum flywheel (Rated to hold 640 lb/tq) ~ $1800

Clutchmasters 725 series clutch kit (Unknown ratings) ~ $1800
Clutchmasters 850 series (Was told it will hold up to 1100hp) ~ 2500
Clutchmasters fx400 + Aluminum flywheel ~ $1800

Car is mainly used for roll racing/drag racing, I dont do really do burnouts/donuts. Out of the 4 what do you think would hold best for street racing and potential 1-2 track days a year?

Any responses are greatly appreciated.

Thank you,
Luis
