Like I said I can't see from that side, For sure the front end falls close to the same time I hear the rpm go flat. Could be a combination of things. We had some success this year tightening the comp 3 ways as tight as they would go on a buddy's car. Though it was a totally different combo. How about the 4 link settings? I/C and bar spread at the housing? Doesn't look like it hits the tire all that hard. It might like more tire load and lower weight transfer. As far as 4 link adjustments I'm no expert. What I do know is there is more to it than just I/C.
