In this suspension tuning guide, we'll explain how to unlock more grip, body control, precision and predictability from your Porsche Spyder RS. With the following Spyder RS suspension upgrades, your car will also communicate its behaviour with greater clarity, which we know is something Porsche enthusiasts love.
We’ll cover the standard car’s handling flaws and reveal the best ways to fix them using Suspension Secrets upgrades.
Spyder RS Overview
Arriving on the scene in mid 2023, the Porsche Spyder RS is based on the 718-series chassis but features a range of performance enhancements.
The car's naturally aspirated, flat-six powerplant also found a home in the 991 GT3 and GT3 Cup racing car. Linked to a seven-speed PDK transmission and revving to 9,000rpm, the output of the four-litre engine is rated at 500hp with 450Nm of torque. These figures provide a 0-62mph time of 3.4 seconds, as well as a 191mph top speed.
Compared to its hard-topped GT4 RS brother, the soft-topped Spyder RS features a slightly shorter front lip and unique ducktail rear spoiler for a less aggressive appearance overall.
In terms of suspension, the Spyder RS is equipped with the same MacPherson strut front and multi-link rear design as the GT4 RS. However, its damper rates are reduced for a more comfortable ride, which has a negative impact on the car's track handling. There are also solid ball joints in more places than the GT4, for example, to ramp up feel and response.
However, this is only the beginning. Read on to discover which Porsche Spyder RS suspension upgrades make the biggest difference to handling performance, overall feel, and of course lap times…
Suspension & Handling Problems (And How to Fix Them)
The Porsche Spyder RS suspension has a wider adjustment window than most other cars, however it's still not a perfect setup.
Main problems
- Front end push/understeer
- Overly soft suspension blunts handling
- Limited camber and toe adjustment (front and rear)
- Nose diving under heavy braking
- Rear skipping under throttle on corner exit
- Excessive front tyre wear during high speed driving
These issues stop the Spyder RS from handling at its absolute best, but leave an opportunity for signifiant gains after suspension upgrades.
The most effective fixes are:
- Increasing front camber to reduce understeer & improve tyre wear
- Adjusting toe angle to enhance traction and stability
- Increasing front and rear spring rates to improve control
- Correcting suspension geometry with a professional alignment
With all these suspension changes carried out, the Spyder RS will realise its true potential on the road and track.
Suspension Geometry & Alignment Setup (Top Tip)
A full suspension geometry alignment is essential after installing new suspension parts.
By correctly adjusting camber, toe, and caster (where available), alignment ensures you maximise grip, stability, and tyre life.
Benefits of a Professional Spyder RS Geometry Setup
- Sharper steering response
- Increased cornering grip
- Improved rear traction
- Enhanced braking stability
- More consistent tyre wear
A professional alignment is the single most cost-effective handling upgrade you can make.
Essential Suspension Upgrades for Porsche Spyder RS
These are the most effective and cost-effective suspension upgrades for the Porsche Spyder RS. These parts form the foundation of all Suspension Secrets handling packages and represent a perfect first step in your upgrade journey.
Camber Caster Plate Top Mounts
Up to -2.4 degrees of front camber is achievable on the stock Porsche Spyder RS suspension, however this is not enough if you're driving hard on track.
Adjustable camber plates from Suspension Secrets allow more negative camber to be dialled into the front axle, significantly increasing front-end grip and improving turn-in response.
Why Camber Plates Matter on the Spyder RS
- Reduce understeer
- Sharpen turn-in
- Increase steering feedback
- Improve tyre wear on track
Suspension Secrets' Spyder RS adjustable front top mounts/camber plates also feature 2 degrees of positive caster angle, improving steering feel and providing dynamic camber gain as steering lock is applied. These camber plates are fully compatible with OEM dampers and PASM, too.
Adjustable Rear Toe Arms
So you've reduced understeer with the front top mounts mentioned above, which allow more negative camber to be dialled into the GT4 RS's chassis. Now it's time to increase the amount of adjustability on the rear axle to further improve cornering grip as well as overall chassis response and predictability.
Although the Spyder RS's factory toe arms offer more adjustment than those fitted to the Spyder RS, their range is still relatively limited and compromises a performance-oriented setup which relies on additional camber. As rear camber is increased to improve cornering grip, it becomes impossible to achieve the toe-in necessary for truly enhanced corner-exit stability and traction.
Suspension Secrets Adjustable Rear Toe Arms offer:
- Greater adjustment range than OEM arms
- Independent optimisation of camber and toe
- Increased cornering stability
- Improved sense of connection to rear axle
Unlike the rubber‑bushed factory arms, our rose-jointed toe arms maintain consistent geometry during acceleration and high-speed cornering.

Porsche Spyder RS Suspension FAQ
What handling problems do suspension upgrades fix on the Spyder RS?
Targeted suspension upgrades correct the Spyder RS’s key weaknesses, including front-end understeer, rear instability under power, excessive nose dive during braking, and uneven tyre wear. Addressing these issues delivers a more predictable, confidence-inspiring car on both road and track.
Which suspension upgrade should I install first on a Spyder RS?
Adjustable front camber plates are the best first upgrade. They unlock additional negative camber beyond the factory limit, immediately improving front-end grip, turn-in response, and steering feel while reducing tyre wear during hard driving.
My Spyder RS feels too soft on track. How do I fix it?
The factory springs prioritise comfort, which leads to body roll and brake dive on track. Uprated springs improve control, stability, and high-speed grip while remaining compatible with OEM dampers and PASM.
