Dinan Progressive Bump Stops / Jounce Bumpers for BMW E9x 3 Series (E90 E92 E93) 325i 328i 330i 335i incl xDrive – Ride Comfort & Handling Upgrade – Suspension Travel Kit – Ideal with Dinan Lowering Springs

Dinan Ride Comfort and Handling Package for BMW E90 E92 E93 3 Series

Unlock extra suspension travel, calmer body control and a more composed drive on British roads with this Dinan progressive jounce bumper kit. Designed to complement Dinan lowering springs on the E9x platform, these tuned progressive bumpstops help your shocks and springs work in harmony for better grip, fewer harsh impacts and more confidence when pressing on.

We have fitted and run this setup on our own E9x builds and customer cars, and the feedback is consistently excellent. Expect smoother ride quality over broken tarmac, crisper turn in and noticeably improved stability under load. If you are lowering your 3 Series and want to avoid bottoming out while maximising performance, this is the proven solution.

Benefits

• Progressive-rate jounce bumpers increase usable compression travel for a calmer, more controlled ride
• Reduces harsh impacts and prevents sudden bottoming on rough roads, speed humps and big compressions
• Enhances front end bite and rear axle composure for greater mechanical grip and cornering confidence
• Optimises effective spring rate when paired with Dinan lowering springs for predictable handling
• Vehicle specific fitment for BMW E9x 3 Series including rear wheel drive and xDrive variants
• Ideal for fast road and occasional track use where consistency and stability matter

Perfect partner for Dinan lowering springs

To achieve the intended ride height, comfort and balance, Dinan recommends installing this bump stop kit alongside the matching Dinan spring set. Skipping the companion kit can lead to compromised ride and handling traits. Dinan will maintain warranty on product defects, but issues related to ride or handling from not using the matching kit are not covered.

What you get

A matched set of Dinan progressive bumpstops engineered to maximise compression travel and refine the behaviour of Dinan springs on lowered E9x models.
