Suspension Secrets Uprated Spring Package - Porsche 718 GT4 RS

Push a standard GT4 RS hard on track and the rear axle can feel unsettled, skipping across the surface mid-corner. A big part of that is the spring balance: the rear springs are stiffer than the factory dampers can properly control, and the front springs let the nose dive under heavy braking, which lightens the rear on turn-in.

This Eibach spring package rebalances the car. The rear rate comes down slightly to suit the OEM dampers, and the front rate goes up slightly to support the car under braking.

What it does

• Calms the rear axle mid-corner and reduces the skipping effect
• Less dive under heavy braking, for a more stable turn-in
• Better front-to-rear balance and more consistent tyre contact
• Allows the car to run up to 20mm below the standard minimum ride height, or stay at standard height if you prefer

Fitment

Fits the Porsche 718 Cayman GT4 RS. A direct replacement for the factory springs, compatible with the OEM dampers, PASM and nose lift. A full geometry setup is required after fitting, and we offer supply and fit with string alignment and corner weighting at our workshop near Leeds.

Developed by Suspension Secrets in the UK using Eibach Racing Springs.
