I have one on mine with stock drivers. Same story, it has some vibration. I only notice the vibration going down the trail or if I'm coasting. If you have it WFO, you shouldn't notice much of it. I had mine on the stand the other day and it looked to me like the inner lugs on the track are what's causing it. It's like they are too steep and hangup on the driver side lugs, not the extroverts. I trimmed the corner off the outside of each paddle to minimize any clearance issues. I do have some wear showing on the center of the outer paddles where it rubs on something.
