The Story:

BMW G2x/G4x monoballs have had their application coverage expanded to now include the BMW G29 Z4 and Toyota GR Supra!

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 motorsport heritage of BMW M (or Toyota’s GR division) 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.

The Dinan Tension Strut Ball Joint Kit provides responsiveness you can feel by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Improves responsiveness by eliminating the deflection inherent in the stock rubber bushings while also reducing brake shimmy. The quietest bearings on the market are virtually noise-free so you can live with them every day. These are the only bearings on the market that are sealed using a rubber boot to keep out dirt and road grime stopping them from wearing out prematurely.

Paired together with the Dinan Rear Toe Link Kit (D280-0025) front and rear suspension deflection is nearly eliminated providing the best possible drivers feel.
