I'm mounting new tires next week and plan on doing the rear with the fixed rotor and chainring on a Marc Parnes balancer.  I'm thinking maybe I should balance the front wheel/tire without the full-floating rotors.   Do the rattling rotors mess up the front wheel balance?

That was not an issue on my bike. Not saying it couldn't be, but I doubt it.
The floating is sideways.........

Thanks, are you guys saying you balanced the complete assembly, tire/wheel/rotors because it made no difference or wheel/tire with rotors added later because it made no difference?  I've seen videos of both ways, would have thought balancing the complete assembly made more sense.

Balancing the complete wheel makes the most sense, whether or not there are floating rotors.

Honestly, the weight and diameter of the rotors make them minor contributors compared to the wheel and especially the tire.

I've always balanced the complete assy, because like Nick says it makes the most sense.

I don't even bother with rears.

I've balanced probably twenty sets of tires on my SS with floating front rotors over the years, always with the rotors in place.

Hope that lends you some little peace of mind.

That is exactly what I'm saying. My own anyway. I'll balance someone else' if they want.

Most balance problems are associated with the wheel, not the tire. I think it's a waste of time.

Well, yeah, the wheel.  Do you balance your own rear wheels?

I check them once.

If they don't require any significant weight I never do again.

intersting.  the tire guys at every track make fun of my monsterwheels and the amount of weights that they seem to take to balance properly, and they like to make fun of how heavy they are. [bacon]
