Dinan 14-21 BMW 228i/230i/428i/430i (F22/F32) Performance Spring Set

Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately, it is highly recommended that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides.
