Outer Turbo Tie Rod / Bump Steer Set, Monoball. Porsche 911 / 912 / 930 / 914  ❭  93034732200

• Porsche 911 1978-1989 3.3L Turbo (930)

• Corrects tie rod angle / drop: Especially on lowered vehicles, the stock tie rod geometry can cause the tie rod ends to sit at an undesirable angle, contributing to bump steer (the tendency for the wheels to turn slightly under vertical suspension movement). The adjustable kit lets you reposition the tie rod so the geometry is closer to optimal.
• Provides a stiff, precise joint: Because it’s monoball (spherical bearing), the joint is more rigid and precise compared to a bush-type joint, with less compliance, thus improving steering feedback and consistency under load.
  
• Allows precise adjustment: Many bump steer kits allow vertical movement in fine increments (e.g. 1 mm steps) to dial the ideal steering geometry.
  
• Maintains alignment under suspension travel: As the suspension compresses or rebounds, the improved geometry helps avoid unintended steering changes (i.e. bump steer), which improves stability and handling.
  
  

• When driving over undulations or bumps, the wheels may steer themselves slightly (you feel the car “pull” or twitch).
• The steering may feel loose, vague, or lack consistency as the suspension travels.
• Especially at the tie rod ends, you may hear clunks, or feel play in steering when the joint is worn.

Why Replacement / Upgrading Matters:

• Correct geometry after modifications: If your car is lowered or has suspension changes, the stock tie rod alignment may cause bump steer. Upgrading to a monoball adjustable kit restores proper geometry.
  
• Improved steering precision: Rigid joints (monoball) reduce compliance and provide sharper, more direct feedback.
  
• Consistency under dynamic load: Helps maintain alignment as the suspension moves, making handling more predictable and safer at speed.
  
• Better durability: Quality monoball joints and upgraded materials withstand fatigue, wear, and stress better than aged or rubber-jointed stock parts.
  
• Essential for track / performance use: In motorsport settings, the steering must remain constant under all conditions — this kit helps ensure that.
