Dinan Suspension Ride Comfort & Handling Kit for BMW 5 Series G30 M550i - Progressive Shock Bump Stops / Jounce Bumpers (Bump Rubbers) for Lowered Suspension - Reduce Bottoming Out - Companion to Dinan Performance Springs

Dinan Ride Refinement and Handling Package for BMW G30 M550i

Transform the way your BMW 5 Series M550i drives after lowering. This Dinan package adds calibrated, progressive jounce bumpers that let a lowered chassis use more of its shock travel for sharper response, smoother compliance and greater confidence on British roads. Built to work in conjunction with Dinan Performance Spring Sets on the G30 M550i, it is the missing piece that keeps a lowered saloon composed over potholes, speed humps and quick direction changes.

• Tuned progressive jounce stops that allow more usable damper stroke on a lowered M550i
• Smoother ride quality with less harsh impact over rough tarmac and abrupt compressions
• Improved stability, cornering balance and traction when pushing on
• Refines effective spring rate for better grip and control vs springs alone
• Essential add-on for anyone running Dinan springs who wants comfort and performance

Why choose this for your G30 M550i

Lowering springs give the stance and steering feel enthusiasts want, but without the right jounce bumpers the suspension can run out of travel and feel crashy. Dinan’s carefully calibrated stops progressively support the car at the limit of compression, so the chassis stays composed and the shocks keep working effectively. We have fitted this upgrade on G30 M550i builds and the feedback from our own testing and customers has been consistently excellent for both ride comfort and handling precision when paired with Dinan springs.
