Product Information
Anti-Roll Bar, Front.
The Porsche Front Anti-Roll Bar is a genuine OEM suspension component engineered to deliver sharper handling and stability for Porsche 911 (996) GT2 and GT3 models. Also known as a front sway bar or stabilizer bar, it links the left and right sides of the suspension to reduce body roll during cornering.

Fits:
  • Porsche 996 GT2 2001-05
  • Porsche 996 GT3 MKI 1999-02
  • Porsche 996 GT3 MKII 2003>>

What This Product Does:
The anti-roll bar connects the left and right front suspension of the vehicle. Its job is to resist body roll (leaning) when cornering. When you go around a corner, the bar twists and applies counteracting force, helping to keep the car flatter.

Symptoms Of A Worn / Failing Anti-Roll Bar:

  • Excessive body roll during cornering, the car leans more than usual in turns.
  • Poor handling stability especially in high speed corners or under load; reduced steering precision.
  • Clunking or knocking noises from the front when going over bumps or changing direction, bushings or mounts for the bar may be worn.
  • Loose or imprecise steering feel, you may feel slack or less control when pushing hard.
  • Uneven tyre wear possibly, if roll or suspension geometry is being affected.

Why Replacement Matters:
  • Restores Handling Performance: a correct, stiff anti-roll bar helps keep the car stable, improves cornering, reduces understeer/oversteer.
  • Enhances Safety: better control in corners, especially in emergency manoeuvres, reduces risk.
  • Protects Related Suspension Components: worn bushings or a failing sway bar can put extra load on other parts (shock absorbers, control arms) causing premature wear.
  • Maintain OEM Dynamics: for Porsche models like GT2 / GT3 the suspension tuning (bar stiffness etc) is part of what makes the driving experience. Using the correct sway bar helps preserve that.
  • Improves Comfort: although sway bars make the ride stiffer, a failing or loose bar typically results in noisy, uncomfortable ride (clunks, rattles), so replacement improves overall feel.

Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.

Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.

But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.

In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.
