rear adjustable control arm

Hello, when do you actually need the rear adjustable control arm? I understand that it is better with it when you lower the car, but I also understand that there are many who are ok without it. How much lower would the car have to be to NEED one? Or are there other significant benefits to an aftermarket rear adjustable arm?

Example: my car is lowered with H&R sport springs. The mininmum camber possible with the adjustment eccentric was -1.5 degrees. If I wanted say -1 degree, I would need adjustable arms to get there.

With a lowered car, non-adjustable original control arms cause unwanted negative camber as the tops of the rear tires angle in too much.

This condition causes uneven tire wear and ill effects on handling.

These adjustable rear control arm correct this problem and can be tuned for any ride height, whether on a street car or a full-on race car.

Adjustment range is in the +1.0 to -3.0 range.

Features Include:

* 4130 Chromoly center bar
* CNC machined billet aluminum end components
* High durometer sqeak free bushing at inboard end
* All installation hardware included

Please let us know if you have any questions! Feel free to shoot me a PM or email.

Best,
Joe
