I think we've gone way out on a tangent. All Im looking for is 1 person to step u and say "yes, these SPC arms helped my wear issues immensely."

 

Sorry to have to say............"Don't hold your breath"

 

Correcting and bring back camber to NOMINAL will help camber wear, and toe wear BUT feathering is a totally different situation as mostly a direction tire problem regardless of camber or toe..........camber and toe can make heel toe feathering worse.

Just as with odd heel wear on human shoes the problem gets solved by buying new shoes.

Lowering even with adjustable arms CHANGES the camber and toe curve not the shape of the curve just where the suspension sits nominally on the curve since the suspension attachment points on the body are lowered thus the angles change.

Why one uses tie rod end spacers to fix the angle of the tie rods to correct the bump steer angle.

 

Q45, in theory I agree 100%. Its unfortunate that (once again) no one has proof that this actually works with swapping out arms.
