I was the one of the people that tested the current relocation bracket before it was released.
In my situation the only time the bracket hits the chassis is when both sides are compressed to full bump. I have not fitted bump stop extensions yet, but I really need 1in ones anyway so the shocks dont bottom out. If you have longer shocks its a good bit of insurance.
This is drivers side normal ride height and passenger side compressed as far as I could (no springs in)
This is both sides compressed as far as I could - you can see why the bump stop extension is required.
