This is a change from the Bilstein damper suspension installed on the 3rd generation RS grade. These are my impressions after 1km of installation.
The ride quality is exactly what you would expect from the high-end OEM suspension that the Roadster RF was designed to offer, and it has been adjusted to suit driving speeds from the street to winding roads.
While the Bilstein damper mentioned above caused the rear to collapse when cornering, this damper suspension never collapses and allows the car to maintain a beautiful posture while smoothly exiting corners.
In terms of hardness, the Bilstein dampers are so strong that they make a loud clanging noise when they hit joints in the road, whereas these absorb shocks quietly. Even when driving long distances of over 500km, I don't feel too tired physically, and I think these suspensions are very well thought out, and it's clear that they were made with a variety of driving conditions in mind. They surpass the performance of the standard RS Bilstein in all areas.
On the other hand, the suspension spring rate itself is soft, so a moderate amount of roll does occur.
We believe this setting was chosen in order to maintain the driving feel characteristic of the Roadster, but if you are considering circuit racing, it would be better to choose the Club Sport Suspension Kit with adjustable damping.
