Suspension Secrets Uprated Spring Package - Porsche 718 GT4 RS
Couldn't load pickup availability
As 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. Therefore, the rear dampers are actually not matched to the spring rate. This causes a hopping and skipping effect from the rear end through corners, which causes instability and oversteer and ultimately reduces driver confidence.
The front axle also contributes to the rear instability as the front springs on the standard GT4RS are actually too soft for the car. This allows the front to compress too much under heavy braking, making the rear axle go light and contributes to turn in oversteer.
To solve this, our engineers tested multiple different spring options on the GT4 RS and found the perfect balance with our selected spring rates using high quality Eibach Racing Springs for optimum longevity and performance. Our spring rates soften the rear axle slightly and stiffen the front axle slightly. This means that our rear springs match the OEM dampers, so they can be controlled through the corners, removing the skipping effect from the car. Our front springs are slightly stiffer than standard too, reducing the dive under heavy braking, keeping the rear wheels in contact with the ground and making turn in much more stable on corner entry.
As a package our spring kit not only improves the front to rear balance of the car, it increases grip and stability substantially and maximises contact patch through the corner, increasing grip levels and driver confidence substantially. As an added benefit, our spring package also allows you to lower the car 20mm lower than the standard minimum ride height to optimise the car for track use too. Standard ride height can also be maintained if you wish using the cars standard ride height adjustment.
The key benefits of the Suspension Secrets Uprated Spring Package for the Porsche 718 GT4 RS are:
- Improved rear axle stability with rear axle "skipping" reduced heavily
- Reduced dive under heavy braking and more stable turn in
- High quality Eibach Racing Springs for optimum performance and longevity
- Direct replacement of the OEM springs with no extra modification required
- Fully compatible with OEM dampers, PASM and nose lift
- Developed in house in the UK
Let customers speak for us
Great Product which was supplied & fitted by Suspension Secrets.
Was added in addition to other Suspension Secrets parts to complete a Fast Road set up on my G87 M2.
Adjustable Height to sit the car exactly where you want it but also the ability to change rake angle to improve the front end positivity and reduce understeer.
Often when modifying suspension - it’s at the cost of road manners & comfort. After a few weeks of use I can happily confirm that the ride quality & manners are unchanged.
A very well set up package with quality components.
Very happy customer. 🙌
Very Impressive visit to Suspension Secrets recently.
The staff were fantastic from start to finish.
I was very well looked after throughout the process with regular updates on progress.
As I had travelled a good distance - the work was completed in a timely fashion and the facilities were more than comfortable while I waited.
I’ve had a couple of weeks now to get used to the new set up and it genuinely has transformed the G87 M2.
The car feels completely planted now and prompts much more confidence - in both wet & dry conditions.
Rear is solid / corner exit traction in a different league.
Front is total transformed - huge difference in turn in confidence & actual grip.
Overall very impressive package and surprisingly OG ride quality & driving manners.
This has clearly been tried & tested to achieve these results.
The way it feels it should have been from factory.
Excellent Results & Performance / Along with a Fantastic / Professional Team.
Highly Recommended.

Jordan is amazing. Package got held up in customs for a while and he communicated swiftly and accurately to get the package released
Awesome products. The camber plates look like works of art, pity they are hidden under the hood!
La verdad un muy buena experiencia los productos son excelentes estoy muy conforme gracias
Excellent made product from quality material. Very happy 😃
Thanks guys excellent service. The Surface Transforms Carbon Ceramic brakes are mega, just done Anglesey and they performed brilliantly, great feel, awesome stopping power and ran much cooler than the standard steel brakes on my GT3. The set up also feels really nice the steering is calmer and more settled on bumpy old back roads(just been to Dumfries on the passes) and has improved the front end on Anglesey’s long late apex corners.
These toe arms are a game-changer for my GR Supra! Paired with KW V3s and solid bushings, they sharpened handling and eliminated rear-end instability on fast road (yet to test on track but will be soon). Adjustable rose joints make alignment precise, boosting corner exit stability with high torque (~700 Nm). Minimal NVH increase on the roads mean there is no real trade off with the upgrade. These are really well made. Comparing them to the stock ones after removal you can defiantly see where your money is going—essential for track enthusiasts!
A great upgrade for my G87 - the car now loves to turn, drives straight and feels so much more agile. The guys at suspension secrets are very knowledgable and super helpful - first class service.
Amazing service and amazing quality parts.
