944 Turbo and 944 S2 – Dual GTS Headlight Conversion


Back in the late seventies 70’s, Porsche was engineering the development of its own racing legends known as the Porsche 924 Carrera GTS and GTR models. During wind tunnel development testing, Porsche determined the serious drag factors associated with the existing Porsche 924 cars pop-up headlight design when the cars were driven ‘lights on / up’.

With the 24 hour race of Le Mans in Porsche’s sights, development work started on a revised complete headlight unit which basically consisted of a ‘recessed bucket’ with a rectangular headlight installed. This assembly was then fitted into the position of the original designed headlight area and removing the additional weight of the lift motor and bar. Once installed, clear Perspex (Lexan) vacuum formed covers were fitted which followed the same lines of the front badge panel meeting the side of the front wings.

This design offered the same aerodynamics during driving at day and night retrospectively. It offered very efficient aerodynamics and consistent weight reduction but it is less efficient than the pop up version when it comes to the comparison of light performance: The steeply raked cover causes light refraction which bends and defuses the light and therewith reduces performance. For racing purposes, the positive effects of improved aerodynamics and weight reduction overweigh by far but for street cars Porsche decided to maintain the pop up design. GTS/GTR headlight conversion kits have been offered by various manufacturers. It has been reported though that fitment and product quality of these products are poor. Out of this situation, in 2008, DEUTSCH NINE developed a high quality authentic Carrera GTS headlight kit which today is produced and offered by RSR9.

Today, in 2010, we have taken the next step and developed a new GTS headlight kit which offers all positive above-mentioned characteristics but on top of that also dramatically improved light performance and more modern looks, so is the perfect solution for anybody who wants an upgrade with the most benefits in one package.

Product Description and Specifications

The Dual GTS headlight conversion kit offered by RSR9 is a complete bolt-in solution meeting the highest quality requirements and provides very precise fitment. It has been specifically developed for the 944 S2 / 951 and includes all parts required for the conversion. This kit has been developed and is manufactured in Switzerland.

The scope of delivery includes two lightweight Dual GTS light housings made from FRP featuring a gelcoat surface and being delivered in primer (almost ready for painting in the cars colour code), two Makrolon UV-resistant covers which can be painted with borders in the colour code of the car, adjustable fitment tubes, headlight units and all hardware required for the installation. The light unit fitting assembly items are made from stainless steel in order to offer best longevity.

The transparent covers are made from 2mm thick Makrolon and precisely replicate the shape of the OEM metal headlight covers.

No drilling needs to be done on the chassis for fitting the GTS headlight units. Both the light housings and each headlight unit may be precisely adjusted. The headlight adjustment can be done by opening the bonnet and is easily accessible.

Fitting the Dual GTS headlight conversion kit to your car offers the following benefits:

  • Considerable weight savings of 13.5kg’s (OEM pop up headlights including lift bar and motor weigh 16kg’s whereas the GTS units only weigh 2.5kg’s). Weight is saved at the very front of the car which is ideal for improved driving dynamics.
  • improved aerodynamics when the headlights are on.
  • high quality and good fitment.
  • Improved light performance (about 60% more output using 2 X 40W bulbs)
  • easy adjustability.
  • more modern looks.

The installation of the Dual GTS headlight kit can be carried out by the average skilled enthusiasts within half a day, fitment instructions and pictures for illustration are included in the scope of delivery. We recommend to stop by a workshop after the installation in order to adjust the headlight settings properly.

Production lead time (if not in stock) is approx. 10 working days from payment.
