To fully enjoy Dinan performance spring sets, pairing them with our 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 who use them with added mechanical grip and cornering power.
Simply put, the Dinan supplemental ride quality and handling kits amplify comfort and performance when paired with performance spring sets.
NOTICE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height, performance, and ride quality.
While not explicitly required, if the matching component is not purchased and installed, less than favorable results in the form of poor ride quality and improper handling traits will occur.
While we will maintain a full warranty on product defects, any claims against the car's improper handling/ride quality traits due to not purchasing the corresponding handling kit will not be warranted.
Fits: BMW; 7 Series; Alpina B7 xDrive; Sedan; F01; 2011-2015.
