What are the benifits of adjustable control arms? I know they change the ride height in the rear, but what does this allow? Im debating what to get for my notch.

 

I have em.... I have weight jakers for lower and adjustable uppers too. First they are stronger and will flex less than stock stamped ones. This will help with traction. Yes.. the lower ones , most have an adjustable spring height which is helpful. Now the importaint part. The control arms are adjustable so you can change the driveshaft pinion angle. This is only realy importaint for drag launches or extreamly lowered cars. The idea is during a launch the rear of the car drops. The agle of the drive shaft will become a bit extreame for gobs of HP.. To correct this the pinion angle is changed to compensate for the suspension drop.

 

+100...........

 

I got them so I could put taller tires on and have adjustability in ride height/levelness
