Dinan Ride Comfort & Handling Kit – Progressive Bump Stops/Bumpstops/Jounce Bumpers for Lowered BMW 3 Series E90/E92 (E9x) Saloon/Coupe 335i & 335i xDrive 2007-2013 – Suspension Bottoming Fix, Shock Travel Upgrade – Companion to Dinan Lowering Springs

Ride Comfort and Handling Package with Progressive Jounce Bumpers for BMW 3 Series E90 and E92 335i and 335i xDrive 2007 to 2013

Transform the way your lowered BMW 3 Series feels on real UK roads. This Dinan ride comfort and handling package adds vehicle specific progressive jounce bumpers designed to complement Dinan spring sets on the E90 and E92 335i and 335i xDrive. By allowing more usable damper stroke and smoothing the transition at full compression, the kit helps the car absorb sharp impacts, resists crashing on big bumps, and boosts cornering stability for a more controlled, confidence inspiring drive.

Lowering without the right bumpstops can lead to reduced shock travel and a harsh, bottomed out sensation over potholes and speed humps. These tuned pieces act as a secondary spring with a progressive rate, supporting the chassis as loads build so your BMW stays composed, tracks straight and puts power down cleanly on B roads and motorways alike. Our team has fitted this setup on customer cars and our own, and the feedback is consistently excellent for ride comfort, grip and predictability.

Key benefits

• Engineered for lowered E90 and E92 335i platforms in both rear wheel drive and xDrive
• Progressive jounce bumpers improve usable damper travel and reduce impact harshness
• Helps the car resist bottoming on uneven surfaces, potholes and speed cushions
• Supports the effective spring rate for better traction and steering precision
• Enhances chassis balance during fast road driving and daily commuting
• Pairs with Dinan spring sets to achieve the intended ride height and handling character

Why this is the ideal partner for your Dinan springs

Dinan springs lower the centre of gravity and sharpen response, while these progressive bumpstops preserve damper motion and refine the last portion of compression. Together they deliver the drop you want with the compliance you need. Installing springs on their own can compromise comfort and control. Adding this handling package completes the suspension solution for the E9x 335i, helping the dampers work in their optimal range and smoothing out rough surfaces.
