Suspension Secrets Rear Upper Control Arm Monoball Kit – Porsche 911 GT3 / RS GT2 / RS (991.1 / 991.2)

Eliminate rear-end vagueness and gain more consistent cornering performance with our Suspension Secrets Rear Control Arm Bush Kit for the Porsche 991 GT3, GT3 RS, and GT2 RS.

The OEM rubber bushes flex under load, causing unwanted movement in rear camber and toe geometry. This flex reduces grip, stability, and the driver’s connection to the rear axle—especially during hard cornering.

Our upgrade replaces those rubber bushes with solid billet aluminium housings and motorsport-grade Rodoball spherical bearings. This ensures immediate force transfer from tyre to chassis, maintaining consistent geometry and delivering sharper response and better feedback at the limit.

This kit includes 8x solid bushes. Only one kit is needed per car. Original suspension arms not included.
