Product Information
De-Cambered Ball Joint For A-Arm Kit – New Type (FI16).

Enhance cornering precision and grip with the De-Cambered Ball Joint Kit, engineered for Porsche 911 and Porsche 914 models.
This “new type” FI16 ball joint includes a built-in negative camber offset of approximately 3 mm, allowing the front suspension to maintain improved tire contact during aggressive cornering.
The result is sharper turn-in, increased lateral grip, and more consistent geometry under load — all without the need for additional camber plates or major suspension modification.
Sold As A Kit.
x2 Kits Required Per Car.

What This Product Does:
  • Standard ball joints are neutral in camber contribution; a de-cambered joint adds a small built-in negative camber to the wheel. This helps counter camber loss under load, especially in spirited cornering or track use.
  • The de­cambered joint helps maintain better tire contact patch under body roll, giving more consistent grip during aggressive driving.
  • Because the offset is relatively small (e.g., 3 mm), it can be a subtle but useful tuning tool without major suspension modifications.

Typical Symptoms / Use-Case Indicators:
  • Camber losses under hard cornering (e.g. inside shoulder lifting)
  • You run aggressive alignment on track setups and want to preserve negative camber under load
  • You want a simple way to bias the geometry slightly without major suspension changes

Why Choose A De-Cambered Joint:
  • Improved Tire Contact Patch – Keeps the tire flatter to the road mid-corner.
  • Better Cornering Balance – Reduces understeer by optimizing front grip.
  • Maintains OEM Geometry – No structural modification needed.
  • Durable, Race-Proven Design – Forged construction handles high loads.
  • Enhanced Precision – Ideal for track-day cars, restorations, and spirited street driving.
