Porsche 911 Backdate

Porsche 911 Backdate

Coupé, 1989


  • 4 years of development
  • TÜV-accompanied development
  • Perfection down to the last screw

When creating this type of vehicle, it was important to us to refine the fundamentally existing aesthetic line of the Porsche and to create a car with technical perfection, which you can use for bread, but with which you also cut a good figure on the race track.

Important: The vehicle shown and described here is a reference vehicle that has already been sold. The vehicle serves as a reference and sample for vehicles manufactured individually according to customer requirements. The vehicle presented, including special equipment, cost 680,000 euros. The specified 595,000 euros refer to our basic version without optional extras and with a 3.9 liter engine with 345 hp.

The vehicle in detail

Classic meets modern

The Porsches converted by Sander are based on the 964 series, whose body, based on the F models, consists of newly designed carbon parts and is equipped with a 4.0 l engine and 369 hp or a 3.9 l engine and 345 hp.

No compromise

During development it was very important to us that we look at the whole car and not just modify parts of it, but look at every part that is there and consider whether it can be improved or replaced, or whether it needs to be redesigned – and before above all, that every change is also TÜV approved. We involved TÜV Nord from the start and discussed and approved all the changes we made with them.

700 pieces redesigned

In this project, not only were the hinges, holders and small parts newly designed and built by us, but also the rims, licensed by the Fuchs company, headlights, indicators and around 700 other parts were replaced. Aside from the engine, one of the most demanding parts was probably the development of a new wiring harness, which resulted in a weight saving of around 20 kg.


This is the new curb weight. With the chassis tailored directly to the vehicle, the RS wheel carriers and the new wheel/tyre combination, the car also cuts a fine figure on the race track.
