An underrated component of a proper driver's suspension the monoball kit (tension strut ball joint kit in today's terminology), is a remnant of an era when road feel was something desirable and sought after. Drivers wanted the visceral feel of being connected to the road as the road-racing heritage of BMW M demanded. Dinan embraced this and over the years mastered its craft into a kit that not only satisfied the desire for proper road feel but also made it livable for everyday driving. While stock suspension properties may have swayed from its golden era lineage to more mainstream ideals, Dinan is here to correct those mistakes for those that want a more M-passioned BMW experience.
