Subaru BRZ Dyno Before and After Drive Shaft Comparison

The CF drive shaft fits without any issues, but we shaved down one stud an 1/8th to make sure the clearance was perfect.

The one bolt we shaved down a few mm

Benefits to having a CF drive shaft: Improved throttle response, more power, lighter weight and can withstand gobs of power.

Beautiful aluminum ends

Driving the car: I can’t say that I feel any major difference, but the numbers don’t lie and it is awesome to have. The car feels more eager to rev and accelerate, which would be expected with less rotating mass. Too bad the beautiful piece of carbon fiber is hidden from view unless you crawl underneath the car.
