De-Cambered Ball Joint For A-Arm - Old Type (FI16).
Upgrade your front suspension precision with this de-cambered ball joint, designed for early Porsche 911 and 914 models (1968-72) using the FI16 suspension system. This ball joint features an offset mounting position, delivering approx 3 mm additional negative camber per side, improving front end grip and cornering response.
Sold Each.
x2 Required Per Car.

Fits:
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 914 (1970-1976)

What This Product Does:

  • By offsetting the ball joint mounting location, the bottom of the strut / control arm is moved slightly outward, thereby increasing the negative camber angle of the front wheels (camber meaning the top of the tire tilts inward). This helps maintain better contact patch under cornering or when the car is loaded laterally. 
  • Improves front end grip and handling when cornering heavily by limiting camber loss under load.
  • Because it uses upgraded hardware, it ensures the A-arm to spindle connection remains precise, reducing deflection or unwanted movement compared to worn standard joints.

Symptoms & When You Might Need It:
  • If you’ve lowered the front of the car, added stiffer springs or anti-roll bars, you may find the standard camber spec is insufficient — tires may roll onto the outer edge when cornering. This de-cambered joint helps adjust for that.
  • Worn or loose ball joints can cause front end play, knocking noises when the steering is turned or when hitting bumps, and uneven tire wear (especially on the inner or outer shoulder). The upgrade version helps eliminate play and adjust geometry.
  • Loss of front negative camber under lateral load: you might notice less cornering grip, front tires scrub or overheat on the outer edge, or the car understeers more than normal.
  • Visible wear: when inspecting, you might find the original ball joint housing is worn, the stud loosened, rubber boots torn, or excessive play when lifting the wheel and wiggling the control arm.

Why This Upgrade Matters:
  • For enthusiasts, track-day users or cars modified with lowered suspension and stiffer springs, the factory ball joint may no longer allow optimal camber and geometry settings. This de-cambered version gives a relatively easy bolt-in method to move the geometry in the right direction without major suspension redesign.
  • It offers both improved handling (by more negative camber) and also improved front end stability and precision (by replacing worn or standard joints with a stronger, correctly designed part).
  • Considering the age of 911/914 front suspension components, renewing joints such as this one is a worthwhile investment in safety, longevity and driving feel.

The lower ball joint connects the wheel carrier to the wishbone and transfers wheel loads to the cross member.

Over time, the rubber sleeve of the ball joint can deteriorate due to dynamic stress and material brittleness, allowing dirt and water to penetrate. To prevent failures, support joints should be regularly inspected for any play. Ball joints should always be replaced in pairs on the same axle.
Driving with a defective ball joint is highly dangerous. In the worst case, the ball head may detach from the joint socket, causing a loss of wheel control and unpredictable swerving.
