Suspension Secrets Uprated Spring Package - Porsche 718 GT4 RS

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
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.
Suspension Secrets Adjustable Camber & Caster Plates - BMW F22 M235i / M240i
Item received as described, well packed and very fast shipping. I am very happy with the product.
These are beautifully machined product.
Fitting was easy, looking forward the the results on the track.
fantastic follow up and advice from the crew at Suspension Secrets on setup as well.
My part stuck at customs i dont have it
I received the package to find very high quality hardware including the hose which was very nice to see. I had my mechanic/body shop complete the install and it looks as if the air entrance ports were always there and part of BMW's design. Granted they should have corrected this airflow issue years ago, it certain looks the part. I live in Texas and it's the dead of summer here in July. I ran the car at my track this past weekend in 100 degree weather for 4-30 min sessions and the air flow worked perfectly as advertised. Not a single brake fade lap even with the hardest braking from 135 mph. Top Notch so far!!
The difference on the cornering is astonishing
Had the SS handling pack fitted to my car, track manners are now spot on with little to no loss to road compliance.
The sharpness of the front end is now on another level. A most for all 991.2 in my opinion.
Excellent quality! Excellent customer service! I've never seen more friendly and helpful folks. Thank You SS people!
Great quality and super helpful staff! Thanks for great products! Especially big big thanks to Mathhew who shipped me new Öhlins specific top nut so quickly! Thanks!
