Restore Proper Rear Camber
Lowering springs and coilovers frequently move rear camber beyond factory specifications.
The Godspeed AK-154-C allows you to:
- Restore factory alignment
- Correct excessive negative camber
- Improve rear tire contact
- Reduce uneven tire wear
- Optimize suspension geometry
The ±3° adjustment range provides ample flexibility for most lowered street and performance applications.
Performance Spherical Bearings
Unlike factory rubber bushings, these camber arms use precision spherical bearings.
Benefits include:
- Reduced suspension deflection
- More precise wheel control
- Improved cornering stability
- Better steering feedback
- Consistent alignment under heavy loads
Because spherical bearings are significantly firmer than rubber bushings, drivers may notice increased road feel, vibration, and suspension noise.
Heavy-Duty Steel Construction
Godspeed builds the AK-154-C using heavy-duty steel alloy designed for long-term durability.
Construction highlights include:
- Heavy-duty steel alloy
- Precision-welded construction
- Corrosion-resistant powder coating
- Durable adjustment mechanism
- Built for both street and track environments
The powder-coated finish helps protect the arms from rust, moisture, and road debris.
Improve Handling & Tire Life
Proper rear camber adjustment offers several performance advantages.
Benefits include:
- Longer tire life
- Improved rear grip
- Better cornering confidence
- Increased suspension stability
- More predictable handling
These improvements are especially noticeable after installing lowering springs or coilovers.
Direct Bolt-On Installation
The camber arms install as direct replacements for the factory rear upper control arms.
Typical installation includes:
- Safely raise and support the vehicle.
- Remove the factory rear upper control arms.
- Install the Godspeed adjustable camber arms.
- Set a preliminary camber adjustment.
- Torque all fasteners to factory specifications.
- Complete a professional four-wheel alignment.
Installation instructions are not included, and professional installation is strongly recommended.
