When you tighten the bolts that steel center sleeve is smashed between the 2 washers and the frame parts holding the sleeve in place. The sleeve doesn’t so much position off the cams shaft.
But a snugger fit would be nice just for piece of mind.

I just put in the white line bushings on mine. The alignment shop had no issues getting it aligned.
They have a very similar setup, but the center sleeve is 3x or so that thick and the cam fit is good.
Having been exposed to white line and Energy I like the white line setup better.
But the bushing material is quite thin so I can’t imagine it provides much cushion. But I can’t tell the ride difference, so theres that.
I’ve also heard black poly may contain graphite where as red may not. Scuttlebutt but there might be something to it.
