Dinan Supplemental Ride Quality & Handling Kit Progressive Bump Stops for BMW F85 X5M & F86 X6M (20152017) Lowering Springs Companion Suspension Upgrade

Ride comfort and chassis control upgrade for BMW X5 M F85 and BMW X6 M F86

Transform the way your F-Series M SUV drives after a drop in ride height. This Dinan kit adds variable-rate jounce bumpers that act as travel optimisers for lowered cars running Dinan drop springs, delivering a calmer, more composed ride on British roads while sharpening body control and stability at speed.

By extending usable suspension stroke and cushioning the final part of compression, these precision-moulded compression stops curb harsh impacts, reduce the chance of hitting the hard stop, and help the tyres stay planted. The result is a BMW X5 M or X6 M that feels tighter over B-roads, more settled on the motorway, and more confidence-inspiring when you pick up the pace.

What you will feel

• Variable-rate jounce bumpers that add controlled support near full compression for a smoother, quieter ride on a lowered F85 or F86
• Extra usable suspension travel that helps prevent hard bottoming and the crashy feel over potholes, speed humps and rough surfaces
• Refined body control that boosts traction, steering precision and road-holding during cornering, braking and acceleration
• Engineered specifically for BMW X5 M F85 and X6 M F86 for an OE-quality fit, consistent performance and predictable handling
• Designed to work alongside Dinan lowering springs to enhance compliance, stability and driver confidence

We have installed this package on customer cars in our workshop and feedback has been outstanding. Pairing these jounce bumpers with Dinan lowering springs gives the aggressive stance you want with the ride polish and control you expect from a premium M car.

FAQs

Why add these with drop springs?
Lowering reduces factory bump travel. These variable-rate compression stops restore usable stroke near the end of travel, improving comfort and control without raising the car back up.

Will they help daily driving as well as spirited use?
Yes. You will notice less impact harshness on broken tarmac and better composure when pressing on, with more consistent grip and stability.

Do they fit like OEM parts?
They are designed for the F85 and F86 chassis for a precise fit and reliable performance when paired with Dinan springs.
