Restore Proper Rear Camber
Factory suspension offers little to no rear camber adjustment after lowering.
The Godspeed AK-184-B 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 sufficient correction for most lowered street and performance vehicles.
Heavy-Duty Steel Construction
Godspeed manufactures the AK-184-B using durable steel alloy designed to withstand demanding driving conditions.
Construction highlights include:
- Heavy-duty steel alloy
- Precision-welded construction
- Corrosion-resistant powder coating
- High-strength adjustment mechanism
- Long-lasting durability
The powder-coated finish helps protect against rust, road salt, and everyday exposure to the elements.
Performance Spherical Bearings
Unlike factory rubber bushings, the AK-184-B uses spherical bearings for increased suspension precision.
Benefits include:
- Reduced suspension flex
- More accurate wheel alignment
- Improved cornering stability
- Faster suspension response
- Consistent alignment under heavy loads
Because spherical bearings are firmer than rubber bushings, expect increased road feel along with slightly higher levels of noise, vibration, and harshness (NVH).
Improve Handling & Tire Life
Proper rear camber adjustment provides noticeable performance benefits.
Advantages include:
- Longer tire life
- Better rear grip
- Improved cornering confidence
- More predictable handling
- Increased chassis stability
These improvements are especially noticeable after installing lowering springs or coilovers.
Direct Bolt-On Installation
The AK-184-B is engineered as a direct replacement for the factory rear upper control arms.
Typical installation includes:
- Raise and safely 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.
- Perform a professional four-wheel alignment.
Professional installation is highly recommended.
Benefits After Installation
Properly adjusted rear suspension can provide:
- Factory-spec alignment after lowering
- Reduced uneven tire wear
- Improved rear suspension geometry
- Better cornering stability
- Increased driver confidence

Final Verdict
The Godspeed AK-184-B Adjustable Rear Camber Arms are an outstanding suspension upgrade for 2001–2005 Lexus IS300 owners looking to restore proper rear alignment after lowering their vehicle. Featuring ±3 degrees of camber adjustment, heavy-duty steel construction, precision spherical bearings, and a direct-fit design, these control arms deliver sharper handling, improved suspension geometry, and longer tire life.
For enthusiasts building a street-driven IS300, drift car, or weekend track machine, the AK-184-B provides the rear camber adjustment needed to unlock the full potential of the chassis.
