Three keys to improved comfort.

More cornering stability
The Spacer tangibly reduces the amount you move around in your seat – in every corner and any on-track situation. It makes you feel at one with your car, giving you better feedback from your driving.
More unique
Every Spacer is unique, just like every racing driver. Our specialists product your seat insert to precisely fit your body and contours. If you need a new Spacer, we’ll make a new one. Using the 3D profile we safely store away, without the new for any new adjustments.
More safety
Spacers are a practical solution to a practical problem, forged out of motorsport experience. Because your Spacer fits your body down to the last millimetre, it will stop you moving around inside the car if you have an accident.


Not just any seat insert. Your seat insert.

Stable, robust, lightweight, flame-retardant: We manufacture each Spacer uniquely using EPP material. The robust high-tech foam material is at the core of the insert, with the high-quality cover finishing it off.
Ability to compare individual driver seating position.
Does your seat unit have an air-cooling system? The seat insert can distribute airflow uniformly in the armrest. All thanks to a milled network of air channels.
Specially made seat inserts produced from a single scan also possible: for endurance races, sprint races, etc.
We produce your Spacer on the basis of a precise, tailor-made seat fitting using your individual driver and vehicle data. This fitting takes around one hour and removes the need for any laborious remeasurement work or subsequent adjustments.
The Spacer brings you and your car together as one. It fills out all the gaps between you and your seat. Not just any racing seat, your racing seat – made with your own data. And for your success!
