That was my first thought as well. I'm curious how it'll do without the rear bar, but since evey guru here runs either without one or with the minimum necessary, I'm sure it'll be great.I put a couple aluminum clamp collars on mine to keep it centered.
It tends to shift one way or the other and would touch just like that.
I ended up deleting the sway bar altogether and the rear feels much more settled.
That may change though with the Cambered rear but with the stock housing it was much better without.
