Rigidity is the name of the game when you’re trying to extract maximum performance from your 991 chassis. By eliminating the large rubber bushing from the OEM rear lower control arm (and hence a large amount of deflection), you add much needed response and feedback into your rear suspension. Each inner piece is fashioned on a 5-Axis DMG Mori CNC, much like a legitimate Porsche Motorsport component. As such, the only bearings that would be suitable to pair with this level of manufacturing come from Aurora—these bearings guarantee long-life, sustained performance and with it, confidence at the limit.
