hi all first of have a good new year what ever you all up to and does anyone know by how much longer rear arms need to be per 1" of lift to keep all things true
These take the strain off the body mount bushes, but are not longer so dont muck up the geometry.
Though you can make longer arms and new body mounts and get less rear steer on full droop and better anti squat.
Becareful if you adjust the length and do nothing with the A frame ball joint your diff input flange will be moved lower if extended and higher if shortened. A few degrees here like moving the bush the wrong side of the chassis (whats that 8mm difference) then you can get a horrible vibration! Horrendus enough to make the vehicle undrivable anything above 25mph!
Been there done that trying to loose a few mm of wheelbase for a trial competition for the weekend. Not my brightest idea but hey ho.
Thats why I said leave the length alone as it knocks out your roll centres.
Though lengthening the arms but leaving the pinion angle the same and adjusting the body mount position results in improvements, I believe giggle pin do such a kit for some mad price
