Narrow Hangers - I felt the car was a little free entering a turn but would have more grip when accelerating out of the turn. The car bounced around a little bit more than usual over the small bumps.

Wide Hangers - I felt the car had more grip, namely side bite, when entering a turn. If you got on the throttle to hard, you would break loose and the rear could wash out. I didn't notice the car getting upset over the smaller bumps

Anyone who has run the B4 platform, I almost compare the feel of Narrow hangers to C hub tower and wide hangers to A hub towers.

Looking forward to hearing your thoughts.
