Dinan 15.8mm Rear Sway Bar (Anti-Roll Bar) for BMW E82/E90/E92/E93 1 & 3 Series 128i 135i 325i 328i 330i 335i 20062013 118% Stiffer Than Stock

Sharpen your BMW’s road manners with this Dinan rear roll control upgrade. The 15.8 mm rear stabiliser dramatically tightens chassis response, cuts unwanted lean in bends and gives you a more planted, confidence-inspiring drive on quick B-roads and at track days. Versus the factory 13 mm bar, the rate is more than double, so you get noticeably flatter cornering and cleaner line control without spoiling day-to-day comfort.

We have run this setup ourselves and our customers consistently report crisper turn-in, improved mid-corner stability and a more neutral balance when pushing on. For drivers who want precise handling and predictable grip from an E8x or E9x platform, this Dinan rear bar is a standout suspension tuning piece.

Why enthusiasts choose this upgrade

• 15.8 mm rear stabiliser for significantly increased roll resistance over the OE 13 mm part
• Noticeably reduces body movement and improves grip on fast road and circuit use
• Enhances steering response and keeps the car composed over direction changes
• Best results when combined with the matching lightweight tubular adjustable 28 mm front bar

Pairing recommendation

For correct front-to-rear balance, pair with the Dinan 28 mm front bar. Matching front bar part number: D120-0530.
