I have a MMA kit on my '20 NS now. The top mount drops down not out, keeping pretty much at the same angle.
That is the benefit of the MMA kit. Its not like to other top mounts bracket lifts that move the top location out. I did my homework at the time.
Pics are seldom, and mine are vaporized, but here is a screen grab of an install vid.
I'll take pics of mine on my rig tomorrow.
The MMA lift is slick and simple, well designed.
I know you know your stuff RJ, but I think you are mistaking kits on this one.
Edit: The Highlifter 3"bracket lift looks to orient such as the MMA, ie lowering the top mount (not angling the shock out). I think it would be a decent lift also.
MMA 2.5" lift
Highlifter 3" lift
Edit: My MMA 2.5" lift. Shock angle not changed. The lift is in the same shock plane/travel as original.
Its good to know.
