Sounds like that the wheel is out of ballance or an out of round tire. We
have spun ballanced tires and wheels on VW's and other earlier american
cars with brake drums on the front. But as far as spin ballancing and
computer ballancing on wheels that go on the front of cars with brake
rotors there is no difference. If computer ballance didn't solve a problem
then spin did. You have something else wrong. If the front brake rotor is
out of ballance then you would feel it when you put on brakes.
Why do you think they ballance brake drums? As far as Triumph rotors I
can't see how spin balance helps.This pertains to steels wheels.
What kind of wheels do you have? Wires or steel. Steel wheels are prone
be bent. This could be the problem. If it is wires, then the spin would
work if you can find someone with a strobe balancer.
