So my need to stay on topic, I did take the Dip out to the Mech.
I kept it at 65/70 on the hwy, and found some solid bumps,
Now first impressions are subjective, but I found while the dip did rebound after a bump, the height was about half, and then no subsequent bouncing. (Porpoising)
I’ll be able to get more than an hour of driving here in a week or so headed down 395
Also noticed that Source sells these air restrictors as well
