Dinan 19-26 BMW 330i/M340i (G20)/21-26 BMW M440i xDrive (G22) Ride Quality & Handling Kit

To fully enjoy Dinan performance spring sets we highly recommend pairing them up with our supplemental ride quality and handling kits. This additional kit includes tuned, progressive rate bump stops that maximize suspension travel on the lowered car for improved handling capabilities and ride quality when compared to just a spring set. By allowing for full compression travel within the spring the possibility of a sudden "bottoming out" is negated, a common unwanted side effect when lowering a vehicle. Bump stops also have the added benefit of optimizing the spring rate, rewarding those that use them with added mechanical grip and cornering power. Simply put, the Dinan supplemental ride quality and handling kits amplify performance and comfort when paired with performance spring sets. G01 / G02 / G20 / G22 / G42 / F95 / F96 Installation labor time is 8.0 hrs (RWD M340i), 8.4 hrs (xDrive M240i / xDrive 330i / xDrive M340i / xDrive M440i), 7.8 hrs (RWD 330i), 9.9 hrs (X3 M40i/X4 M40i) or 11 hrs (X5M/X6M) if the supplemental ride quality & handling kit is installed by itself. Installation labor time will be negligible if installed at the same time as the corresponding Dinan Spring Set.

• Bumpstops are made from OE quality material for progressive characteristics.
• Bumpstops are carefully tuned for use with Dinan springs.
• Includes 4 bumpstops.

The Dinan D193-0121 Supplemental Ride Quality & Handling Kit is designed to complement Dinan performance spring sets on select BMW applications. This kit includes tuned, progressive-rate bump stops that maximize usable suspension travel on lowered vehicles, helping improve handling and ride quality compared with using performance springs alone. By allowing the spring to compress through its intended range, the kit helps reduce the likelihood of abrupt bottoming while supporting more predictable suspension behavior.
Dinan bump stops are carefully calibrated for use with Dinan springs and help optimize the effective spring rate. The result is improved mechanical grip, enhanced cornering performance, and a more controlled driving experience without sacrificing the benefits of a performance-oriented suspension setup. The kit is recommended for drivers seeking a balanced combination of responsive handling and everyday ride comfort.
The Dinan D193-0121 kit fits select BMW G01, G02, G20, G22, G42, F95, and F96 platform vehicles, including specified BMW X3, X4, 330i, M340i, M240i, and M440i applications. It includes four bump stops and is intended for use with the corresponding Dinan spring set. Installation labor may be substantial when installed separately, but installation time is minimal when fitted at the same time as the matching Dinan springs. Professional installation is recommended to ensure proper suspension service and fitment.
