Dinan Supplemental Ride Quality and Handling Kit for BMW F30 340i, RWD and xDrive

Unlock the full potential of your lowered BMW 340i with the Dinan Supplemental Ride Quality and Handling Kit. Designed to work in harmony with Dinan Performance Spring Sets, this suspension upgrade adds tuned, progressive rate bump stops that maximise suspension travel on a lowered F30. The result is improved ride quality, sharper handling, and greater confidence on British roads without the harshness often associated with lowering springs.

If you are running or planning to run lowering springs on your BMW F30 340i, this Dinan kit is the must have addition. It prevents bottoming out, optimises effective spring rate, and delivers more mechanical grip and cornering power. We have installed this kit on our own and customer cars and the feedback has been consistently positive. Better compliance over bumps, tighter control in fast corners, and a more composed, OEM plus ride feel.

Why add the Dinan Ride Quality and Handling Kit to your 340i

Lowering a BMW 340i with performance springs reduces available compression travel. Without the correct bump stops you can experience a crashy ride, inconsistent handling, and premature bottoming out. Dinan’s progressive rate bump stops are specifically tuned for the lowered ride height, allowing the suspension to use its full travel smoothly. This optimises the effective spring rate through the stroke, increasing mechanical grip and making the car more predictable and enjoyable to drive.

Recommended pairing

For the advertised ride height, performance and ride quality, pair this kit with the matching Dinan Performance Spring Set for the BMW F30 340i. Running springs without the corresponding ride quality and handling kit can lead to poor ride and improper handling traits.
