I think I may have a wheel bearing going. It's only around 100km/h that it shakes, only when I'm accelerating or braking do you REALLY notice it. Once I get her to about 120km/h it seems to tone down. They did balance them and everything, They've got sticky weights on them as well so I don't feel that that vbrations are coming from them. Let me tell you though... theres no other feeling like rolling on dubs. haha
