Suspension Secrets Lower Control Arm Inner Monoball Porsche 911 (991) GT3/RS GT2/RS

Increase chassis sharpness and suspension precision with our Suspension Secrets Lower Control Arm Inner Monoball for the Porsche 991 GT3.

The OEM inner control arm bushings use soft rubber, which flexes under load. This allows geometry to shift mid-corner, making the car feel vague and disconnected—especially at the limit.

Our billet aluminium monoball replacements eliminate that flex, maintaining stable suspension geometry and delivering more direct chassis feedback. It’s a must-have upgrade for precision handling and sharper response.

Key Benefits:

• Increased chassis rigidity and response

• Consistent suspension geometry under load

• Sharper steering and improved front-end feedback

• Ideal replacement for ageing OEM rubber bushings

Materials & Construction:

• CNC-machined 6082 T6 billet aluminium

• 316 stainless steel components

• Motorsport-grade bearings

• Designed and manufactured in the UK

Vehicle Fitment:
