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

Introduction

This kit includes 8x solid bushes – Only one purchase required for complete monoball kit. This kit does not include the original rear suspension arms.

When cornering hard, the rear control arm bushes of the 991 GT3 / GT3 RS flex. This flexing causes the rear camber and rear toe angles to change dynamically, resulting in inconsistent levels of cornering grip.

During hard cornering, lateral forces are exerted on the tyres as the mass of the car shifts. This movement of forces initially impacts the tyres, then the rear control arm bushes and then finally to the chassis. The flexing of the rubber bushes results in a delay between driver inputs and the feedback felt from the chassis, resulting in a vague sense of connection to the rear axle.

To solve this, we’ve designed our Suspension Secrets Rear Control Arm Bush Kit for the Porsche 991 GT3 / GT3 RS. Our bushes are machined billet aluminium with solid motorsport-grade Rodoball spherical bearings that replace the OEM rubber bushes. Our solid bushes ensure cornering forces are transferred immediately from the tyres into the chassis. This increased responsiveness between tyres and chassis results in better feedback and response. Simply put: driver input immediately matched by chassis output

Our solid bushes also ensure rear camber and rear toe remains constant during a corner, resulting in greatly improved cornering stability and traction.

The key features of the Suspension Secrets Rear Control Arm Bush Kit for the Porsche 991 GT3 / GT3 RS are:

• Increased rear axle stability on road and track

• Improved sense of connection to rear axle

• Increased cornering grip and traction

• Improved responsiveness and cornering agility

• Motorsport-grade Rodobal bearings
