Why use adjustable rear control arms?
With a lowered car (either for street or track use), the
non-adjustable original arms cause unwanted negative camber - the tops of
the rear tires angle in too much, causing uneven tire wear and unwanted effects
on handling. The adjustable rear control arm corrects this problem
and can be tuned for any lowering, whether a street car ro a full-on race
car through a +1.0° to -3.0° range.
Co-developed with OE-supplier SPC Performance, the combination of OE engineering
and UUC's enhancements make these arms truly "ultimate".
With so many
alternate choices, why UUC?
Our custom-made
proprietary design resolves many of the issues with other brands:
-
Aluminum center rods
are known to bend and fail under extreme use or after extended use (build-up
of strain/weakening). Failure of a suspension part that keeps the
wheel in place can be quite dangerous. UUC's chromoly center rods
are the strongest in the world, virtually unbreakable in this application.
-
The wrench-fixing
point of UUC's chromoly arm will not "round off" like the fixing
point of aluminum arms.
-
UUC's original-style
bushing is silent, and does not have the squeaks and rattles associated
with the use of heim joints or spherical bearings.
-
The combination of
aluminum ends and chromoly steel center bar results in a reasonable weight,
a balanced combination of mass and strength.
- UUC's stress-relieved aluminum cleavis end is not only very
strong, but is also much more precise in fitment than stamped-steel alternatives.
Construction
details:
Center bar: plated 4130 chromoly steel.
End components: CNC-machined anodized aluminum for lightness, stress-relieved
for strength and durability.
Inboard bushing: high-durometer squeak-free rubber.
All hardware included.
Installation
instructions:
(Professional installation recommended. Alignment is necessary for correct
camber adjustment.)
1. Before beginning any alignment always check for loose or worn parts, tire
pressure and odd tire wear patterns. Determine amount of rear camber needed.
Raise rear of vehicle and support body on jack stands.
2. Remove the inner and outer rear lower control arm mounting bolts and remove
the arm from the vehicle.
Note: It may be necessary to lower the rear member to fully remove the inner
bolt.
3. Install the chromoly adjustable arm using the OE bolt on the inboard side
and the new supplied bolt on the outboard side. Lower the vehicle and torque
both bolts to manufacturer's specifications.
Note: Tightening the bolts with the vehicle in the raised position may cause
premature bushing wear due to preloading the bushings.
4. Adjust camber by loosening jam nuts and turning the center piece to desired
camber specification.
Note: The maximum length of the arm is reached when the flat on the end of
the center adjusting rod is visible. Do NOT lengthen the arm beyond this point.
5. Tighten the jam nuts, set rear toe to specifications, complete alignment
and road test the vehicle.
