I bought a Porsche 911 996 3.4-litre Carrera back in September 2016. It was in pretty good condition, but after 18 years' use and 55,000 miles, its suspension was well past its best. Also, out of the factory the car was set up with plenty of understeer built in to make it far more benign than any 911 before it. I wanted to make my car not only feel like new, but better than new.
And so a complete suspension overhaul was needed. I decided to go with Ohlins Road and Track coilovers, Powerflex polyurethane bushes and adjustable anti-roll bars and drop links. Please note that in this video all the parts were supplied by the relevant manufacturers free-of-charge for use in the video. However, I selected them based research as to which set-up would be most suited to my needs for the car. Design 911 also did the work free-of-charge, once again I chose to feature them in the video due to their expertise in Porsche parts supply and fitting.

Anti Roll Bars / Sway Bars – Improved Handling and Body Control
Anti roll bars, also known as sway bars, are suspension upgrade components designed to reduce body roll during cornering and improve overall vehicle stability. By linking the left and right sides of the suspension, anti roll bars resist excessive chassis movement, helping the car stay flatter through corners and delivering sharper, more predictable handling.
At Design911, our range of anti roll bars includes high-quality OE replacement and performance upgrade options from trusted suspension brands. Whether you’re refreshing worn factory components or upgrading for fast-road and track use, anti roll bars are one of the most effective ways to enhance handling without compromising ride comfort.
What Do Anti Roll Bars / Sway Bars Do?
Anti roll bars are torsion bars mounted across the
suspension axle that control lateral body movement when cornering. Their main
functions include:
- Reducing body roll during turns
- Improving cornering balance and grip
- Enhancing steering response and driver confidence
- Distributing load more evenly across the suspension
By limiting excessive chassis lean, sway bars allow tyres to maintain better contact with the road, improving traction and control.
Why Upgrade Your Anti Roll Bars?
Upgrading anti roll bars is a popular suspension
modification because it offers:
- Noticeable handling improvements with minimal impact on ride comfort
- Better control during spirited driving or track use
- Improved balance between front and rear suspension
- Reduced understeer or oversteer when correctly matched
Performance anti roll bars are often adjustable, allowing fine-tuning of suspension balance to suit driving style, tyre choice and road conditions.
When Should You Replace or Upgrade Anti Roll Bars?
Anti roll bars should be replaced or upgraded when:
- Factory suspension feels soft or unstable during cornering
- Rubber bushes or mounting hardware are worn or damaged
- Upgrading other suspension components such as springs or dampers
- Preparing a vehicle for fast-road, track day or performance use
Replacing tired components or upgrading to performance sway bars restores precise handling and improves overall driving enjoyment.
At Design911, we supply anti roll bars and suspension upgrades that meet professional workshop standards and enthusiast expectations.
