Dinan 20-25 BMW X3 M/X4 M (F97/F98) 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. F97 / F98 Installation labor time is 10.3 hrs 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.

Enhance the performance of your lowered BMW with the Dinan D193-9701 Ride Quality and Handling Kit. Designed specifically for BMW X3 M and X4 M models with F97 and F98 chassis codes, this supplemental kit works with Dinan performance spring sets to improve suspension travel, ride quality, handling, and cornering performance. The kit includes tuned, progressive-rate bump stops that help maximize available compression travel and reduce the risk of harsh bottoming out commonly associated with lowering a vehicle.
Dinan carefully tunes these bump stops for use with its performance springs, helping optimize the effective spring rate and improve mechanical grip during spirited driving. Progressive characteristics allow the suspension to respond more predictably under compression, supporting a better balance between comfort and control. For best results, pair the kit with the corresponding Dinan Spring Set. Installation requires approximately 10.3 hours when performed separately; labor is negligible when installed at the same time as the appropriate Dinan spring set.
The Dinan D193-9701 kit includes four bump stops manufactured from OE-quality material for reliable fitment and consistent performance. It is designed for select 2020-2022 BMW X3 M and X4 M applications, including F97 and F98 models. Professional installation is recommended to ensure proper suspension assembly and performance.
