Suspension Secrets Uprated Spring Package - Porsche 981 / 718 Cayman GT4
Couldn't load pickup availability
If you have ever driven your Porsche Cayman GT4 hard out on track or even on the roads, you will have noticed that the car feels very soft with a lot of body roll through the corners. This is due to the Cayman GT4 being designed by Porsche as a road car and with comfort in mind as well as performance. For most owners though, performance is often more important than comfort as the Cayman GT4 is usually used more for spirited driving than cruising.
When we were developing our own shop 718 GT4 we noticed how much the chassis rolled and moved around through the corners and under heavy braking out on track. This not only reduces driver confidence, but it holds the car back in terms of cornering performance, leading to slower cornering speeds, less effective braking performance and ultimately slower lap times.
Therefore, our engineers developed an uprated spring package as part of our full Porsche 981/718 GT4 Circuit Handling Package Kinematics Kit using Eibach Racing Springs for maximum performance and longevity. Once fitted, the GT4 had much more stable body control with significantly reduced body roll through the corners. This allowed the car to be much more stable and controlled when cornering, ultimately allowing higher G force through the chassis and a higher speed through the corners.
Due to high demand, we are no offering the springs from within our full kinematics kit separately so you can upgrade your stock springs in isolation if you already have other upgrades fitted to the car.
The uprated spring package stiffens both the front and rear axle, which also improves stability under heavy braking. With a firmer spring at the front axle, dive is reduced under heavy braking which keeps the rear tyres in contact with the ground, improving turn in stability and helping to reduce understeer on corner entry. Despite being stiffer than standard, the spring rates we have developed are also perfect for road use and still offer compliance and suability out on the roads.
The spring rates in this kit also work perfectly within the range of the OEM dampers and work perfectly with the standard shocks and PASM system.
The key benefits of the Suspension Secrets Uprated Spring Package for the Porsche 981/718 GT4 are:
- Significantly reduced body roll through the corners, maximising cornering speeds
- 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 and PASM.
- Developed in house in the UK
Let customers speak for us
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.

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.
