cheap 3 link
Reply #3 –
the stock upper arms, bushings, and mounts arent designed to individually take the full load of an singular upper arm.
if you are gonna go swappin out arms and reinforcing mounts, jus build a real third link and mounts.
also "can work" and "works ok," are not the same thing.
there are performance drawbacks to the PM3L as well, due to the angle of the upper and the offset location on the housing. there is more information than any one person could handle about the PM3L over on CC.
