Correct Rear Camber After Lowering
Lowering springs and coilovers frequently push rear camber outside factory specifications.
These adjustable control arms allow you to:
- Restore factory alignment
- Correct excessive negative camber
- Improve rear tire contact
- Reduce uneven tire wear
- Fine-tune suspension geometry for street or track use
The estimated ±3° adjustment range provides enough flexibility for most lowered Lexus applications.
Pillowball Bearings for Precision
Instead of traditional rubber bushings, this kit uses pillowball (spherical) bearings.
Benefits include:
- Reduced suspension deflection
- More precise wheel control
- Improved cornering stability
- Faster suspension response
- Consistent alignment under heavy loads
Because spherical bearings are significantly stiffer than rubber bushings, expect increased road feel and a slight increase in noise, vibration, and harshness (NVH).
CNC Tubular Steel Construction
The control arms are built using high-quality CNC-machined steel alloy for strength and durability.
Construction highlights include:
- CNC-machined steel alloy
- Tubular performance design
- Industrial powder-coated finish
- Corrosion-resistant construction
- Low-profile upper plate for additional clearance
The tubular design offers increased rigidity while maintaining adequate clearance around suspension components.
Improve Handling
Correct rear camber settings help improve overall vehicle dynamics.
Benefits include:
- Better rear-end grip
- Improved cornering confidence
- More predictable handling
- Sharper chassis response
- Increased tire lifespan
These improvements are particularly noticeable on lowered vehicles used for spirited driving.
Direct Bolt-On Installation
The AJP Distributors camber arms install using factory mounting points.
Typical installation includes:
- Raise and safely support the vehicle.
- Remove the factory rear upper control arms.
- Install the adjustable camber arms.
- Set a preliminary camber adjustment.
- Torque all hardware to factory specifications.
- Perform a professional four-wheel alignment.
Installation instructions are not included, and professional installation is strongly recommended.
Benefits After Installation
Properly adjusted rear suspension can provide:
- Longer tire life
- Improved rear grip
- Better suspension geometry
- More stable cornering
- Factory alignment after lowering
Pros
- Fits multiple Lexus GS and IS models
- Estimated ±3° rear camber adjustment
- Heavy-duty CNC tubular steel construction
- Pillowball bearings improve suspension precision
- Durable powder-coated finish
- Direct bolt-on installation
- Excellent for lowered street, drift, and track cars
- Additional suspension clearance from low-profile design
Cons
- Professional alignment required
- RWD models only
- Pillowball bearings increase NVH compared to rubber bushings
- Installation instructions are not included
Final Verdict
The AJP Distributors Rear Upper Adjustable Control Arms Camber Kit is an excellent suspension upgrade for 1998–2005 Lexus GS300, GS400, GS430, and 2001–2005 Lexus IS300 owners looking to restore rear alignment after lowering. With estimated ±3-degree camber adjustment, CNC-machined tubular steel construction, and precision pillowball bearings, this kit delivers improved handling, more accurate suspension geometry, and longer tire life.
For enthusiasts building a lowered daily driver, drift car, or track-focused Lexus, these rear upper control arms provide the adjustability needed to maximize suspension performance.
