Suspension Secrets Rear Upper Control Arm Monoball Kit — Porsche 911 (991) GT3 RS / GT2 RS

When cornering hard, the rear control arm bushes on the 991 GT3/GT3 RS flex — causing rear camber and toe angles to change dynamically, resulting in inconsistent cornering grip. This flex also creates a delay between driver inputs and chassis feedback, giving a vague sense of connection to the rear axle.

Includes 8× solid bushes — only one purchase required for a complete monoball kit. Does not include the original rear suspension arms; this kit retrofits into your existing arms.

Fits Porsche 911 (991) GT3 RS and GT2 RS.

Price includes applicable US import tariffs and fees for this UK-manufactured product.
