Dinan F30 3 Series RWD Suspension Upgrade - Progressive Bump Stop/Jounce Bumper Kit & Handling Pack for Lowered F30 Saloon - Companion to Dinan Lowering Springs - Fits BMW 320i 328i 330i (2012-2016) - Improve Ride Quality, Damper Travel & Grip

Transform your F30 ride and handling with Dinan’s companion kit

Give your lowered 3 Series the suspension support it deserves. The Dinan supplemental ride quality and handling kit is the ideal partner for Dinan performance spring sets, using carefully calibrated progressive bump stops to unlock extra shock travel, smooth out harsh impacts, and deliver confident turn-in with impressive mechanical grip.

If you are chasing a sharper chassis without sacrificing comfort on British roads, this suspension enhancement is the missing piece. It keeps the car composed over bumps, cuts the chance of bottoming out, and helps the dampers work in their ideal range for both daily driving and spirited B-road runs.

Why enthusiasts choose this suspension upgrade

• Progressive-rate bump stops that increase usable suspension stroke on a lowered car
• Smoother compression over potholes and speed humps with reduced harshness
• Improved cornering traction and body control thanks to optimised effective spring rate
• Helps prevent sudden bottoming, protecting dampers and enhancing stability
• Designed to complement Dinan lowering springs for the intended drop and ride quality

Real-world results

We have fitted this kit on our own builds and customer vehicles, and the feedback is consistently positive. Drivers report a more compliant ride, tighter response in quick direction changes, and a calmer, more controlled feel over rough surfaces. It simply makes a lowered F30 feel right.

Important pairing note

For the advertised drop, balance and comfort, fit this kit together with the matching Dinan performance spring set. Installing springs without the corresponding bump stops can lead to a compromised ride and less predictable handling. This kit is purpose-tuned to work with the lowered ride height.
