For those of you wondering which one is Inge in the photo, you will have to wait until you meet us on a event or you should read this blog post about Inge.
As with so many beauties from the world of glamor and the German-speaking A, B, C and Z celebrities, Inge was not really presentable before her first photo shoot or the appearance was deceitful. After a few detours, Inge came from the USA state of Colorado to mcchip-dkr in Germany.
Fortunately the experts did not throw their hands up in despair, but instead had a complete restoration program in mind for the legendary RSR. After all, beneath the color, the wheels of time and the road it traveled had a heavy impact on her condition. Even in the last country most people probably wouldn’t have touched her because often timed nobody wanted to have anything to do with a Porsche 911 from the early seventies and eighties…
As any die-hard fan of air-cooled Porsche knows, the RSR back then, was the lighter and sportier version of the 911 Carrera RS 2.7. At the time, only 49 copies were produced by Porsche’s customer motor sport division, although some say it’s nearly 60 models. This US model is a 911 RSR IMSA, built in 1975, and the mcchip-dkr team has done a great job on this Porsche.
But before we proceed with Inge, we will explain why we as a “coilover manufacturer” are exhibiting on classic shows. In brief: Many lovers of classics complain about the lack of up-to-date performance from their standard suspension. Of course back then when Jaguar E-Type, BMW 02, Porsche F-Model, Porsche G-Model and Co. came on the market, the suspension technology was nowhere near as advanced as it is today.
Hardly any classic car, from that time, can take full advantage of the performance that modern tires alone offer nowadays. We have been offering an extensive product range of vehicle-specific coilovers for years, with the latest damper technology for classic cars and young classics and we will continue to expand it. We have never really made a big deal out of it.
To perfect the requirements of suspension kits for classics, our modern damper setups have been configured on our 7post vehicle dynamics test rig and further fine-tuned during test drives on the road, which ensure more driving safety and performance without disregarding the comfort.
Our KW classic suspension kits have a part certificate and offer the possibility of a continuous lowering within the tested range. Depending on the application, the classics suspension systems are available in three different damping versions. In addition to the series developments, we offer drivers of exclusive classic cars and young classics the option of producing an individual suspension according to the customer´s custom-made requirements through our KW motorsports department.
We make sure to take into account all requirements, which can differ significantly depending on the intended use on the road, rallies, participation at classic rallies or at historical motor sport events, in terms of driving height, ground clearance, wheel loads, spring travel, spring stiffness and damping measures. But let´s get back to talking about Inge.
Inge, also known as “Mädchen & Motoren Porsche” (Girls and engine Porsche), was not only restored, but was completely rebuilt and “modernized” for the use in the German young classics Trophy. In addition to the other modifications, a safety cage including flank protection came on board and of course it was not screwed, but welded as it needs to be on a real racing car.
The newly made wide fenders were made of glass fiber reinforced plastic. Fans of “RWB- or Rocket-Bunny-Bolt-on-widenings” will probably be left out in the cold …
The air-cooled six-cylinder boxer engine is also no longer the boxer that was enhanced for the RSR from 2.7 liters to 2.8 liters, but now is a reworked 3.3 liter from the Porsche 911 Turbo (G-model). The engine is not an open throttle valve system, but a flat slide system, as was used back then in the historical motor sport.
But the mcchip-dkr team has also reworked the complete interior as well as the auxiliaries of the air-cooled boxer motor. While the 2.8-liter of the RSR 300 had 300 hp, Inge marched forward with 345 hp.
Of course, everything was fine-tuned on the tuner’s dynamometer. By the way, the powerful wing at the rear is the Group 5 rear spoiler.
The suspension is a KW Competition 2A racing suspension in an inverted monotube version. In contrast to our pure street suspensions, you can see the thicker piston rods. Here, the damper forces can be adjusted separately in compression and rebound stages.
For the Porsche purists who do not drive their classic Porsche on the Nordschleife or racetrack every weekend, we have developed a damper kit which can be adjusted separately in compression and rebound stages, so you can continue to use the original torsion bar springs. Find out more in the YouTube video above.
Inge also stopped by KW in Fichtenberg to perfectly fine-tune the KW Competition suspension on our 7post rig to fit her model dimensions – forgiveness – weight distribution, tires, wheel loads and Co. Our “7post rig” was also used by Polyphony Digital, together with Kazunori Yamauchi, to develop Gran Turismo 6.
For those of you who still have an eye for the front apron, you might recognize the slightly modified IMSA bumper with its own front splitter because Inge is not just a Porsche that is getting dusty in a museum or a private collection and only being exhibited occasionally at fairs.
Inge is quite hardened and tough and feels at home not only on the Nordschleife but the Nürburgring Grand Prix circuit.
At numerous historic motor usages, she stood up to the competitors and was driven full line of battle. That´s the way it has to be!?
If you would like to take a closer look at Inge, you can do this at some classic shows here in Germany or even on some race events. But Inge is now already wearing a you livery.
