Elephant Racing caster arms provide adjustable caster and anti-dive ability when used on the front
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.
Fully weather sealed – Proper boots at the heim joint keep water and contaminant out for extended life.

The coffin arm controls wheel movement and suspension geometry while allowing smooth suspension articulation during steering, braking, and cornering.
It connects the wheel carrier to the chassis/subframe and works together with the shock absorber and track control arms to maintain:
• Precise steering response
• Stable wheel alignment
• Ride comfort
• Porsche handling characteristics
The integrated bushes absorb vibration and road harshness, while the lower ball joint allows controlled movement of the suspension assembly.
Functions & Technical Role
• Suspension geometry control: Maintains correct wheel alignment and movement
• Integrated lower ball joint: Allows smooth articulation during suspension travel
• Vibration damping: Suspension bushes reduce harshness and road vibration
• Handling stability: Supports accurate steering and chassis balance0
• OEM engineering: Manufactured to Porsche factory specifications for exact fitment and durability
Fitment / Position on Car
• Fitting position: Front or rear axle depending on model/application
• Side: Left = Right
• System: Suspension and steering geometry control
Typically installed as: Front lower control arm or Rear lower control arm (GT/Turbo applications)
The coffin arm plays a major role in steering precision, suspension stability, and tyre wear control. Worn bushes or ball joints can negatively affect handling, ride comfort, and alignment accuracy.
When to replace
• Knocking or clunking from suspension
• Excessive play in the ball joint or bushes
• Uneven tyre wear or poor wheel alignment
• Vague steering or unstable handling
• During suspension rebuild or overhaul

The lock nut fastens the control arm to the wheel carrier, helping keep the suspension arm securely mounted in its correct position. This connection is important for maintaining suspension geometry, wheel alignment, and stable handling. Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.
Functions
• Secures the control arm to the wheel carrier
• Helps maintain correct suspension alignment and geometry
• Supports stable wheel location during driving, braking, and cornering
• Helps prevent loosening caused by road vibration and suspension movement
• Provides a secure OE Match replacement for the original lock nut
• Suitable for suspension repair, control arm replacement, or wheel carrier service
Suspension lock nuts are safety-critical fasteners and may lose locking strength after removal. They can also become corroded, damaged, rounded, or worn over time. Replacing the lock nut during suspension work helps ensure the control arm is secured correctly and reduces the risk of loosening after reassembly.
When to replace
• This Part The control arm has been removed or replaced
• The wheel carrier or suspension arm connection has been dismantled
• The original nut is corroded, damaged, rounded, or seized
• The nut no longer tightens or locks correctly
• Suspension repairs or alignment-related work are being carried out
• There is play, looseness, or noise from the control arm mounting area
• As recommended during service where single-use locking hardware is removed

This lock nut fits in the suspension assembly, at the control arm to wheel carrier mounting point. Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.
Functions
• Secures the control arm to the wheel carrier
• Provides a factory-correct M12 x 1.5 locking fastening point
• Helps maintain suspension arm stability and alignment
• Prevents loosening caused by road vibration and suspension movement
• Supports correct suspension geometry and wheel control
• Helps ensure safe and secure mounting of chassis components
• Provides OE Porsche fitment, thread size and fastening quality.
Control arm lock nuts are exposed to road dirt, moisture, corrosion and high suspension loads. Over time, the nut can corrode, seize, round off or lose its locking ability. Because this fastener secures a critical suspension joint, it is good practice to replace it whenever the control arm is removed or replaced.
Using a Genuine Porsche OE lock nut helps ensure the control arm is correctly secured to the wheel carrier and maintains the factory-standard suspension assembly.
When to replace
• When replacing a control arm, wishbone or coffin arm
• When removing or refitting the arm-to-wheel-carrier joint
• If the original nut is corroded, seized or damaged
• If the thread is worn or the locking function is compromised
• During suspension overhaul or chassis repair work
• After accident repair or wheel carrier replacement
• When restoring the suspension with correct OE Porsche hardware.

Suspension bolts in this location are subject to high load cycles, tolerance wear, and exposure to elements. If the original bolt is stretched, corroded, or re-used beyond service life, it can compromise alignment, introduce movement in the suspension joints, and lead to poor handling or uneven tyre wear. Replacing with the correct bolt restores the secure clamping required for optimal rear suspension performance.

• Position on Vehicle: Rear axle, lower control arm (support link) that positions and controls the rear wheel hub/wheel carrier relative to the chassis sub-frame.
• Applications: Recommended when the original control arm is bent, corroded, has worn bushings/joints or when you’re renewing the rear suspension to restore handling performance and tyre wear.
The rear lower control arm is a key component in maintaining wheel alignment, suspension stability and tyre contact consistency. A failing or compromised arm can cause poor handling, uneven tyre wear, rear-end instability, and alignment drift. Replacing helps restore original ride and handling precision.
When and why to replace:
• You experience clunks or knocking from the rear when going over bumps or during cornering.
• Uneven wear on rear tyres or inability to keep rear alignment within spec.
• Bushings or joints show play or corrosion.
• The vehicle is high-mileage or has been subjected to high stress, track use, or suspension removal.
• As part of a full rear-suspension refresh or rebuild.
