H&R Anti-Roll/Sway Bar Kit (Front 28mm 2-Way, Rear 20mm) for BMW 4 Series F32 F33 F36 (Typ 3C) Coupe/Cabrio/Gran Coupe xDrive 4WD 4-Cylinder - Excludes 420xi & 428xi

Uprated stabiliser set for BMW 4 Series F32 F33 F36 xDrive 4-cylinder models

Get your 4 Series turning in quicker, cornering flatter and putting power down with confidence. This German-engineered H&R roll-control kit replaces the factory bars with precision-formed, motorsport-grade units that dramatically cut lateral lean and bring a more neutral balance to your AWD BMW. Ideal for fast-road use and track days, with everyday comfort retained.

We run these bars on our own cars and customer builds at MJ Modifications and the difference is immediate. Steering feels more connected, mid-corner stability improves and the chassis becomes far more predictable. Customers consistently report less push at the front, cleaner exits and increased confidence on B-roads and motorways alike.

Highlights

• Front bar: 28 mm, two-position adjustable for tailored front-end response
• Rear bar: 20 mm, fixed-rate to complement the front and promote a balanced chassis
• Noticeably reduces roll for flatter, faster directional changes
• Enhances grip distribution to curb understeer and improve traction on xDrive
• Refined ride quality suitable for daily driving

Engineering and build

• Manufactured in Germany from high-tensile spring steel
• One-piece, non-welded construction for strength and longevity
• Cold-formed then heat-treated for consistent rate and durability
• TÜV approved for quality and safety
