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

Elephant Racing caster arms provide adjustable caster and anti-dive ability when used on the front, and adjustable wheel base, weight distribution, and anti-squat when used on the rear.

Front Suspension

Threaded double-adjuster makes it easy to extend or shorten the arm.

This makes for easy caster adjustment – an important adjustment the factory left out. A must-have for cars with GT3 style extendable style lower control arms to correct for un-intended caster increase that is caused by the extended LCAs.

Anti-dive behavior can also be adjusted. Lowering the front of the arm using the provided spacers reduces front dive under braking. Adjustable in 2mm increments.

Rear Suspension

Adjustable Caster Arms can reduce rear overhang and rear weight bias. A must-have for cars with GT3 style extendable style lower control arms. Adjust the length of the caster arms to correct the position of the rear wheels that have been drawn forward by aggressive camber settings. Even over-compensate for less rear weight bias than stock.

With the heavy mass of the engine cantilevered behind the rear axle, even small changes in wheel base make significant changes in weight distribution. Shortening the overhang reduces the famous 911 "pendulum" effect in corners.

Anti-squat behavior can also be adjusted. Raising the front of the caster arm using the provided spacers reduces rear squat under acceleration. Adjustable in 2mm increments.

Fully weather sealed> – Proper boots at the heim joint keep water and contaminant out for extended life.

If not using Adjustable Lower Control Arms

1999-2012 996, Boxster, Cayman, & GT3 Front: Bolt on if replacing the lower control arm central bushing with 2290022 / 2290014 rubber bushings, or our 2180011 camber adjusters.

1999-2012 996, 997 & GT3 Rear: Straight bolt on.

2006-2018 997, Boxster, Cayman, & 991 Front: Requires fitment of our part number 2290022 or 2290014 LCA central bushings or 2180011 solid caster bushing kit

About Control Arms Front

Front Control Arms – Precision Steering and Suspension Control

Front control arms are critical suspension components that locate the front wheels, control suspension geometry and maintain precise steering alignment. By connecting the chassis to the wheel hub, control arms manage camber, caster and toe movement throughout suspension travel, directly influencing handling stability, steering response and tyre wear.

At Design911, we offer front control arms ranging from OE-spec replacements to performance upgrades from trusted suspension brands. Whether replacing worn factory arms or upgrading to adjustable or reinforced designs, front control arms are essential for restoring sharp handling and improving front-end confidence.

What Do Front Control Arms Do?

Front control arms form a key part of the suspension system, allowing controlled vertical movement of the wheels while keeping them correctly aligned. Their main functions include:

  • Maintaining correct wheel alignment and geometry
  • Supporting steering precision and stability
  • Controlling suspension movement under braking and cornering Isolating road impacts while maintaining control

They work together with bushes, ball joints and dampers to ensure predictable handling and consistent tyre contact with the road.

Why Upgrade or Replace Front Control Arms?

Upgrading front control arms is beneficial because it offers:

  • Restored or improved steering accuracy
  • Reduced unwanted suspension flex under load
  • Improved tyre wear and alignment stability
  • Enhanced feedback during spirited driving

Performance control arms may feature uprated bushes, stronger materials or adjustable geometry, allowing fine-tuning for fast-road or track-focused setups.

When Should You Replace Front Control Arms?

Front control arms should be replaced or upgraded when:

  • Ball joints or bushes are worn, cracked or noisy
  • Steering feels vague or unstable
  • Uneven tyre wear is present
  • Performing a suspension refresh or performance upgrade
  • Alignment cannot be set correctly

Replacing worn control arms restores proper suspension geometry and significantly improves handling confidence.

At Design911, our front control arms meet OE or performance standards to support reliable servicing and enthusiast-level upgrades.
