Sphericals™ performance bearings deliver a new level of handling and ride quality. This is the only performance bushing replacement that delivers ball-type spherical bearing action with stock front control arms.
The secret is in the ball-shaped bearing that allows continuous self-alignment, preventing binding and allowing the suspension to work and move freely. Springs and dampers do their job of controlling the suspension without interference from excessive friction or binding from the bushings.

Self-aligning spherical ball action – cutaway view
Sphericals Eliminate Binding
With ordinary performance bushings, binding happens when the axis of the front and rear mounts are not collinear. Their hard-compound and minimal compliance cause even minor misalignment of the mounts to pinch and bind, preventing free movement of the control arm. Binding can happen in both static (car is stationary) and dynamic (chassis is flexing) conditions. Sphericals eliminate binding
Dynamic Binding
Dynamic binding is due to chassis flex. This happens anytime the car is cornering, braking, accelerating, or going over bumps. Control arm mounts move with the chassis flex, deviating from their static alignment to cause binding, pinching and resisting free movement of the suspension. The chassis flexes when you most need free suspension movement; to absorb bumps, and during hard cornering when you need grip for performance.

Porsche A-Frame Wishbone
At Design911, we supply a wide range of a-frame wishbone parts and bushes for Porsche models, helping you maintain, tune and upgrade your suspension to suit everyday road use, fast-road or track driving.
Why do Porsche A-Frame Wishbone parts matter?
A-frame wishbones and their bushes are key links between the chassis and the wheels on your Porsche. They locate the suspension, control how the wheel moves through its travel and help keep alignment where it should be. As original components age, rubber can soften or crack and joints can wear, which affects how precisely the car steers and how stable it feels. Replacing tired arms or changing bush type lets you restore the intended geometry or move to a firmer, more controlled setup.
- Keep your Porsche feeling precise instead of vague or wandering
- Help suspension geometry stay consistent for stable, predictable behaviour
- Address play, knocks and visible wear in bushes and joints
- Support long-term enjoyment, confidence and potential resale appeal

When should you review or replace your Porsche a-frame wishbone?
Checking a-frame wishbone components and bushes regularly helps you catch wear, damage or age-related deterioration before it affects confidence behind the wheel or leads to more expensive repairs elsewhere in the suspension.
- Clunks over bumps, vague steering, pulling under braking or wandering on the road
- Uneven or rapid tyre wear that points to geometry or bush issues
- Visible cracks, perishing, or play in bushes and joints on inspection
- After impact damage, heavier use or when carrying out wider suspension upgrades
If any of these apply, it is a good time to review your a-frame wishbone components and replace anything that is past its best so your Porsche stays dependable and reassuring to drive.
