De Madsters, de Speed Service 964 backdates

First of all, what is a 964 Backdate?

You might think that the trend towards so-called retro-moderns is something new, a recent phenomenon triggered by a tidal wave of enthusiasm for classic cars combined with the desire to use them as a modern car.

It's a trend that's easy to understand, with the benefits obvious: some of the most iconic classics of yesteryear have been remixed with modern mechanics to deliver a stunning and unique driving experience, with that delicious style we love so much. at classics. But certainly the greatest exponent of the retro-modern philosophy and the most appropriate is the Porsche 911. They make undeniably stunning objects. Keeping its beautiful classic look, but being relatively modern, it is a feast for the eyes and heart of the driver.

Speed ​​Service started building its own 964 backdates in 2015. The first Madster was launched at the InterClassics and TopMobiel fair in the MECC in Maastricht 2016.

We have now developed a new and improved 964 Backdate, the MADSTER RT. These Porsche 964 backdates were built entirely in-house at our location in Sittard, the Netherlands. All body modifications are made of steel and are made by hand. A large number of parts are designed and manufactured by us in-house.


Madster RT

This Porsche 964 backdate was built entirely in-house at our head office in Sittard, the Netherlands. Our head office is located in a fully renovated farmhouse built in 1726.

From where we can do metal work, high quality paint, engine and gearbox overhaul, engine superflow test bench etc, all under one roof.

We are one of the few companies that perform bodywork transformations from steel. Everything is made by hand by our highly skilled staff.

Each car is therefore unique, like a work of art.


By the time Singer introduced their first car, the orange G-model backdate, they were taking advantage of social media in a great way! The pictures of this car went viral and later people got used to their great cars and the price for such a special and personal Porsche retroactively. As you can see there are many companies worldwide that want to do the same. But there are many companies that try to copy Singer, and we at Speed ​​Service certainly don't want to do that. It takes thousands of hours to backdate a 964, so make it your own!

That's our philosophy. Every Madster built and every customer is treated with passion and personal attention to detail.

To improve on this we also have our own rendering program for the Madster. So that we can create a virtual Madster together with the customer. Many details can be discussed immediately and adapted to the wishes of the client. This gives them a good idea of ​​what their dream Porsche will look like.


We have changed many details on this Madster RT to make it perfect for customer requirements. Such as designing and creating in-house: headlights, taillights, aluminum electrically adjustable mirrors, custom exhaust and the list goes on. Despite the steel body parts, the weight of the car is equal to the iconic 964 RS, 1220 KG! Powered by the 330 hp engine, it is a thrill to drive this car. Upgrades to 380 hp are an additional option.

We are currently even developing an air-cooled 4-valve engine, so we can upgrade the power to 400 hp.


The third Madster this time a Targa is coming the second quarter 2022.


We're already talking to some clients from around the world about new commissions so we can build even more awesome personalized Madsters in the years to come!
