One of the most cost-effective chassis upgrades available for the Porsche 996 and 997 — replacing the OEM rubber bushes in the upper rear arms with Fluro spherical bearings for a dramatic improvement in rear suspension precision and feel.
The standard rubber dogbone bushes are engineered to absorb noise and vibration — which is fine for a family saloon, but it also means compliance, vagueness and inconsistency under lateral load in a sports car. Swap them for spherical bearings and that compliance disappears entirely. The rear end becomes more planted, more predictable and significantly more communicative. It's a change that experienced drivers feel immediately.

Should I fit these with coilovers?
Yes — we always recommend fitting spherical dogbone bearings at the same time as a coilover or spring kit. The improvement in body control from the suspension is amplified by the elimination of bush compliance at the rear upright. These two upgrades complement each other directly.
