H&R Anti Roll Bar Kit Audi S1 8X (Front & Rear 24mm) – 33806-2

H&R Anti-Roll Bar Kit – Audi S1 8X

If your Audi S1 feels like it leans too much through corners, or lacks the sharp, confident feel you want from a hot hatch, an upgraded anti-roll bar kit is one of the most effective chassis improvements you can make. This H&R kit replaces both the front and rear anti-roll bars (also called sway bars) with thicker, stiffer items – reducing body roll and giving the car a more planted, responsive feel through bends.

H&R is a well-regarded German suspension manufacturer with a strong reputation in the performance and motorsport world. This kit is engineered specifically for the Audi S1 on the 8X platform, so it is designed to work with the car’s existing geometry and suspension setup rather than against it.

What Does an Anti-Roll Bar Actually Do?

An anti-roll bar connects the left and right sides of an axle. When the car leans through a corner, the bar resists that lean and helps keep the body flatter. A stiffer bar means less body roll, better tyre contact with the road, and more predictable handling. This is particularly noticeable on the S1, which – despite its all-wheel drive system – can feel soft through faster corners when running standard suspension components.

What This Kit Includes

• Front & Rear anti-roll bar: 26mm diameter, upgraded from standard fitment
• Manufactured from high-tensile 50CrV4 chromium-vanadium steel alloy with precision-forged ends
• Durable powder-coat finish for corrosion resistance
• High-quality bushings included for direct, responsive feel

How It Improves the S1

On the road, the difference is noticeable even in everyday driving – less lean through roundabouts and bends, a more direct feeling through the steering, and greater confidence during quicker changes of direction. For anyone who enjoys a spirited drive, the car simply feels more composed and controlled.

During performance driving or on track, the benefits become more significant. Keeping the body flatter through corners means the tyres maintain better contact with the road surface, which improves grip and allows for sharper turn-in. Upgrading both the front and rear bars together – rather than fitting just one – is important for maintaining a balanced handling response. Fitting only a front or rear bar in isolation can upset the balance of the car and lead to unpredictable handling.

It is worth setting realistic expectations: this kit will meaningfully improve handling feel and reduce body roll, but it works best as part of a considered suspension setup. If you are also running lowering springs or coilovers, the two upgrades complement each other well.

Build Quality

H&R produce this kit in Germany using 50CrV4 chromium-vanadium steel – a high-tensile alloy widely used in performance and motorsport suspension components. The ends are precision forged for strength and accurate fitment, and
