ECS Tuning Front & Rear Sway Bar Kit (Anti-Roll Bars) for BMW E8x/E9x (E82/E88 1 Series & E90/E92/E93 3 Series) incl. M3, 135i, 335i (N54/N55) 28mm Front, 15mm Rear

ECS Tuning Roll Control Bar Set for BMW E8x and E9x Platforms

Unlock serious chassis composure with this ECS Tuning roll control package for the BMW E8x and E9x platforms. By increasing roll stiffness at both axles, this stabiliser set delivers flatter cornering, quicker steering reaction and a more confidence-inspiring balance on fast road and track day driving, without ruining day-to-day ride quality.

We run these bars on our own builds and customer cars and the feedback is the same every time: crisper turn in, stronger mid-corner support and a planted, predictable rear end through rapid direction changes. If you want real-world pace and control from your 1 Series or 3 Series, this is the upgrade.

What you get

• Front axle bar diameter: 28 mm
• Rear axle bar diameter: 15 mm
• Precision-matched bushes with integrated sleeves to reduce compliance and minimise bind
