Lowering your vehicle can dramatically improve its appearance and handling, but it can also introduce unwanted changes to suspension geometry. One of the most common problems is excessive rear negative camber, which reduces the tire’s contact patch and can quickly wear away the inside edge of expensive performance tires.

The Whiteline Rear Control Arm Lower Rear Outer Double Offset Bushing Kit (W63430) provides an economical solution by adding up to ±1.5 degrees of rear camber correction.

Rather than replacing complete control arms, Whiteline utilizes a specially designed double-offset bushing system that allows the position of the control arm to be altered during installation. This provides additional adjustment range to help bring rear camber back into specification or dial in the alignment for a specific suspension setup.

Ideal for Lowered Vehicles

Lowered vehicles are particularly susceptible to increased negative camber as suspension ride height changes.

While some negative camber can improve cornering performance, excessive camber reduces the amount of tire contacting the road during straight-line driving. This can contribute to accelerated inner tire wear and reduce available traction during acceleration.

The Whiteline W63430 kit provides the additional correction needed to optimize rear alignment after lowering, helping maximize the tire’s contact patch for improved traction, handling, and tire life.

It’s especially valuable for vehicles running wider or expensive low-profile performance tires where maintaining proper alignment can make a significant difference in tire longevity.

More Alignment Control Without Replacing the Arms

Whiteline’s offset bushing design adds useful alignment correction while retaining the factory-style suspension architecture.

With up to ±1.5° of available camber adjustment, your alignment can be better tailored around vehicle ride height, suspension modifications, tire setup, and intended use.

Whether you’re correcting the alignment after installing lowering springs or coilovers, trying to reduce excessive inner tire wear, or dialing in the rear suspension for improved performance, the Whiteline W63430 Double Offset Bushing Kit provides a simple and effective solution.
