Just got a set of aluminum C4 halfshafts to shorten and put in my car... Whats the deal with balancing these? Is it necessary? I was quoted $60/shaft to shorten and another $60/shaft to balance. I hate to be a cheap ass, but if its not necessary... :hunter:
I figure my max speed I would ever want to go is 140ish? I think thats a little over 6500RPM in 4th, divide by 3.55 and I get under 2K RPM halfshaft speed. Seems kinda slow but then again, I dont know much about drive line balancing.
These things seem feather-light compared to my steel BB halfshafts too... I know the wall thickness is a little thin, but Im not big on burnouts and power shifting so I think they will live behind my small block. Id rather twist one of these than shear a stub axle anyway.
