Dinan Suspension Travel & Ride Comfort Kit - Progressive Bump Stops/Jounce Bumpers for BMW F30 3 Series 335i & 335i xDrive (2012-2015) Saloon/Sedan - Lowered Car Bottom-Out Fix - Handling Upgrade, Comfort Pack - Optimised for Dinan Lowering Springs

Transform the way your BMW F30 335i drives on British roads with this genuine Dinan suspension enhancement pack. Purpose-built for lowered 3 Series saloons running Dinan springs, it uses tuned, progressive-rate jounce stops to unlock extra compression travel, reduce harsh impacts and deliver calmer, more controlled handling without the crashy feel often associated with a drop in ride height.

Built for lowered F30 335i and 335i xDrive

If you’ve fitted lowering springs on a 2012 to 2015 BMW 3 Series F30 335i or 335i xDrive, this companion kit is the missing piece that refines comfort and stability. By optimising bump stop engagement on the F30 chassis, it helps the suspension work through more of its stroke, improving compliance over potholes, speed humps and rough B-roads while boosting confidence in quick direction changes.

What you’ll feel

• Smoother ride on imperfect tarmac thanks to progressive-rate jounce bumpers that add usable compression travel.
• Reduced bottom-out events on lowered setups, minimising jolts and protecting dampers.
• Stronger mechanical grip and flatter cornering with more predictable chassis behaviour.
• OEM-like fitment, engineered specifically for the F30 platform for consistent, repeatable results.
• Ideal pairing with Dinan springs for a tidy stance and everyday usability.

Proven on UK roads

We’ve installed this Dinan upgrade on customer F30 335i builds and our own cars. Feedback is consistently positive: better bump absorption, less crash over big compressions, improved traction exiting bends and a more composed drive in daily use. It’s the simple way to keep the look you want while restoring comfort and control.

Compatibility

• BMW 3 Series F30 335i RWD saloon, 2012, 2013, 2014, 2015
• BMW 3 Series F30 335i xDrive AWD saloon, 2012, 2013, 2014, 2015

Designed to work in tandem with Dinan springs on the F30 3 Series platform.

Important info

For the intended ride height, comfort and handling balance, install this Dinan supplemental kit together with Dinan springs. Running springs alone can lead to reduced travel and a harsher, less controlled ride.
