First off PBM is top tier for adjustable links. SPL and Stance are nothing close to this. The quality is amazing and the adjustability is more than any company out there.
This is a comparison with my Megans that were almost maxed out. As you can tell the PBM offer a great deal of adjustability. The double lockers make sure the alignment settings will not move. Adjusting them is very easy with the use of a large adjustable wrench. No need to remove the lock bolts.
The Circuit Sports lockout washers are great for the money. They remove the eccentric washers and make sure the alignment is spot on. They come with very high grade treated hardware. The washers are lazer cut for precision and the can be installed/uninstalled without removing the swaybar.
