Dinan Handling Kit | BMW 335is (11-13) (D193-9081)

The Dinan 11-13 BMW 335is Handling Kit is a performance upgrade designed to enhance vehicle handling and ride quality. This kit includes tuned, progressive rate bump stops that work in conjunction with Dinan performance spring sets to maximize suspension travel on lowered vehicles. By allowing full compression within the spring, it prevents bottoming out—a common issue when lowering cars—while also improving mechanical grip and cornering power. Constructed with precision tuning, these bump stops optimize spring rates, resulting in improved handling capabilities and ride comfort for spirited driving or track use.

This handling kit is specifically designed for 2011–2013 BMW 335is models. It is a direct upgrade intended for vehicles equipped with performance springs, providing a comprehensive solution to enhance suspension performance. Suitable for street and track applications, the kit includes tuned bump stops that complement existing suspension components. Installation involves bolt-on replacement of factory bump stops, making it an effective upgrade for lowering vehicles while maintaining ride quality and handling dynamics.
