F55/F56.
To fully enjoy performance spring sets from Dinan, pairing them with supplemental ride quality and handling kits is highly recommended.
This additional kit includes tuned, progressive rate bump stops that maximize suspension travel on the lowered car for ride quality and handling capabilities 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 cornering power and added mechanical grip.
Simply put, the supplemental ride quality and handling kits from Dinan amplify comfort and performance when paired with performance spring sets.
Installation labor time is 6.8 hrs (includes alignment) 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.
