Caster Tuning
Our Caster Adjuster allows you to tune this important setting that the factory left out. A must-have for cars that have extended lower control arms (GT3 control arms or eccentric monoballs) to correct for un-intended caster change that is caused by the extended arms.

Caster is also a great tuning aid for adjusting out understeer. Our Caster Adjusters let you tune the caster you need.

Two eccentric mounting points increase range of adjustment by up to 25mm. Choose from the inner bore for minor caster adjustments or the outer bore for extreme adjustments.

Rear Weight Bias
For the rear suspension, our Caster Adjuster can reduce rear overhang and rear weight bias. Cars with aggressive rear camber actually draw the wheels forward, increasing rear weight bias. Use our Caster Adjuster to compensate and even over-compensate for less rear weight bias than stock

Maintain Proper Alignment
Our Caster Adjuster is solid aluminum to hold alignment settings precisely. Stock rubber bushings compress under load, allowing alignment to wander and making the car less predictable. Our solid design eliminates compression, improves precision and maintains geometry true.

Functional Design Built To Last
Available for factory type lower control arms (wishbones) front and rear, including stock type arms and GT3 arms

Set of 2 x Adjustable lower control arms - 1 pair, required per axle

Elephant Racing adjustable lower control arms provide the camber, caster and precision you need. Length adjustable similar to the factory GT3 control arms, but without the need for shims.

Quick and Easy Adjustments – No need to keep a stock of shims on hand, length is easily adjusted by rotating the center hex head. Rotate clockwise to expand or counter-clockwise to contract the arm length.Adjustments can be made within minutes. No shims to mess with. Perfect setup to make quick changes for the track.

Widen Track – Use in combination with our camber plates on the front, or our adjustable length arms upper control arms on the rear to widen the track. This allows you to achieve a wider track without altering the scrub radius as happens when using wheel spacers.

Heim Joint – Our spherical bearings eliminate the deflection associated with rubber bushings. These bearings maintain stable suspension alignment, and improve feedback.

Fully Weather Sealed – Proper boots at both the ball joint and heim joint ends to keep water and contaminants out for extended life. These arms are suitable for extended road and track use.

Camber Adjustment – Extended range of adjustment lets you achieve aggressive camber. Or you can dial it back to get a factory street alignment on lowered cars.

Caster Adjustment – Our Caster Adjuster allows you to tune this important setting that the factory left out. A must-have for cars that have extended lower control arms to correct for un-intended caster change that is caused by the extended arms. Rotate the center puck and bolt down to secure the setting.

The arms are fully rebuildable with replaceable heim and ball joints.

On 996, 997, & 991 Cars:
Center puck can be also used as a wheelbase adjuster on the rear to draw the wheels back to improve weight distribution. It is a great tuning aid for adjusting out understeer

Litronic Bracket – This bracket is required for cars that are originally equipped with the litronic headlights. This adapter bracket attaches to the headlight angle sensor.

About Control Arms Rear

Rear Control Arms (Coffin Arms) – Stability, Alignment and Rear-End Control

Rear control arms, commonly referred to as coffin arms, are critical suspension components responsible for controlling rear wheel alignment, stability and handling balance. Mounted between the rear hub and chassis, these arms manage camber and toe movement as the suspension compresses and extends, directly affecting traction, tyre wear and overall vehicle confidence.

At Design911, we supply OE replacement and performance rear coffin arms from trusted suspension manufacturers. Whether you are addressing worn factory components or upgrading for fast-road and track use, rear control arms play a vital role in maintaining predictable handling and restoring proper suspension geometry.

What Do Rear Control Arms (Coffin Arms) Do?

Rear control arms locate the rear wheels and guide their movement through suspension travel. Their primary functions include:

  • Maintaining correct rear wheel camber and toe
  • Providing rear-end stability under acceleration and cornering
  • Supporting predictable handling balance
  • Reducing unwanted suspension flex

Because the rear suspension governs traction and stability, worn or flexing coffin arms can significantly affect handling feel and tyre life.

Why Upgrade or Replace Rear Coffin Arms?

Upgrading or replacing rear control arms offers:

  • Restored rear suspension geometry and alignment accuracy
  • Improved traction and stability during cornering
  • Reduced uneven tyre wear
  • Better feedback and control during spirited driving

Performance rear control arms may feature stronger materials, uprated bushes or adjustable geometry, allowing fine-tuning of rear suspension setup for performance driving or track use.

When Should You Replace Rear Control Arms?

Rear coffin arms should be replaced or upgraded when:

  • Suspension bushes are cracked, worn or noisy
  • Rear alignment cannot be set correctly
  • Handling feels unstable or unpredictable
  • Uneven rear tyre wear is present
  • Performing a suspension refresh or performance upgrade

Replacing worn rear control arms helps restore factory handling characteristics and improves overall driving confidence.

At Design911, our rear control arms meet OE or performance standards, supporting both professional servicing and enthusiast upgrades.
