Dial Out Rear End Wander Under Hard Cornering
Worn rear inner toe arm bushings let the toe link shift under load, causing rear steer that shows up as inconsistent corner exit grip and a nervous rear end at speed. The Whiteline W63157 replaces the soft factory rubber with a synthetic elastomer bushing engineered to hold precise toe geometry through hard driving.
Key Features
- Synthetic elastomer construction resists oil, grease, ozone, and weathering far longer than factory rubber
- Internal grease reservoirs provide continual self lubrication to manage friction over time
- Protective plating and powder coating on metal components resists corrosion in harsh conditions
- Reduces unwanted rear toe change under acceleration, braking, and cornering loads
- Restores consistent rear end tracking for more predictable corner exit grip
- Direct replacement for the factory rear inner toe arm bushing
- Backed by Whiteline limited lifetime warranty

FAQ
What is the W63157?The W63157 is a Whiteline rear inner toe arm bushing kit made from synthetic elastomer, designed for the 2008-2009 Pontiac G8 and 2010-2015 Chevrolet Camaro to replace worn factory rubber bushings at the rear toe arm inner mounting position.
What vehicles does this kit fit?This kit fits the 2008-2009 Pontiac G8 and the 2010-2015 Chevrolet Camaro, which share the same Zeta rear suspension platform.
How do I know if my rear toe arm bushings are worn?Common symptoms include rear end wander at speed, inconsistent grip on corner exit, clunking from the rear suspension over bumps, and uneven rear tire wear caused by toe changing under load.
What material are these bushings made from?They are manufactured from Whiteline's synthetic elastomer compound, chosen for its resistance to oil, grease, ozone, and weathering compared to factory rubber.
Does this kit come with grease for installation?Yes, installation grease is included to lubricate the bushing during and after fitment.
What warranty does Whiteline offer on this kit?Whiteline backs this kit with a limited lifetime warranty against manufacturing defects.
Will installing this kit stiffen my ride noticeably?Synthetic elastomer bushings are firmer than factory rubber, which improves rear toe control, but Whiteline formulates its compounds to balance handling gains with a livable ride for daily driving.
Can this bushing be installed with the toe arm still on the car?Most installers remove the rear toe arm from the vehicle to press the old bushing out and the new one in, then reinstall the arm and set toe with an alignment.
Install Instructions
