Suspension Secrets Uprated Spring Package - Porsche 718 GT4 RS BMW this part will add thatAs standard, the Porsche GT4 RS suffers with instability at the rear axle which is especially obvious when being pushed hard out on track. One of the main reasons for this is that the front and rear spring rates are not perfect matched for optimum chassis balance and damper efficiency. The rear axle is over sprung and underdamped. This is mainly due to the GT4 RS being a car manufactured by Porsche with different components from already existing cars.
