Made in Bürrig
Since the early 1980s, enthusiasm for the fascinating sports cars from Stuttgart-Zuffenhausen has been growing inexorably. ROOCK-Sportsystem can look back on numerous national and international successes in motorsport since then: in 1996, the team celebrated class victory in the GT2 category at the ‘24 Hours of Le Mans’ and won the FIA GT2 World Championship in the same year.
ROOCK Sportsystem also set standards in historic motorsport: victories at the ‘24h Le Mans Classic’ in 2016, 2018, 2022 and 2025
underline its exceptional expertise. The original Porsche 911 RSR 3.0 racing car, perfectly prepared by ROOCK Sportsystem, was driven by Michael Roock and Uwe Alzen. With the fastest time and
pole position, the team secured victory in the GTS class.
With professional planning, uncompromising attention to detail, state-of-the-art technology and decades of motorsport experience, Michael Roock is passionately dedicated to the restoration of
historic Porsches and the construction and deployment of racing cars.
Pure passion
With careful care and regular maintenance, they are among the most robust vehicles around. So it's no wonder that their owners have the highest standards when it comes to choosing a service
partner.
The ROOCK-Sportsystem workshop employs specialists who perfected their craft at Le Mans, Daytona and Spa-Francorchamps and celebrated their masterpieces with champagne. Under the leadership of
Michael Roock, these same experts restore and maintain the precious historic racing cars in our inventory.
Our valuable classic cars undergo regular inspection and maintenance, restoration with engine and transmission repairs, complete repairs including painting, and bodywork conversions in our modern
workshop.

911 T/R 2.0 1968 | original vehicle
After the factory holidays in 1967, Porsche developed a sports model for the 1968 season for professionals and ambitious amateur drivers.
Around 30 vehicles were produced. The basis was a 911 T body from Karman production, these bodies were approx. 30 kilograms lighter than the bodies from Stuttgart. Hence the name 911 T for the T
body and the R for Rallye. The lower weight was due to the lightweight body and the elimination of the emergency seat, flaps, trim, insulation material and the replacement of the sports seats
with Recaro bucket seats. The interior fittings, instruments, stabilisers and brakes were carried over from the 911 S. For the engines, there was a choice between a tuned 911 S engine with
approx. 180 hp and an engine from the 906 with twin ignition and 46 Weber carburettors with an output of 210 hp. The gearbox could be ordered with sports gears and limited slip differential,
depending on choice. All 911 T/R were supplied with a 100 litre petrol tank and a roll bar at the rear. It was also possible to order 6-inch or 7-inch rims for the rear axle. The so-called 7R rim
from the 911 R.
The 911 T/R was a very successful sports model that was able to achieve class victories in many endurance races, such as the 1000 km Nürburgring, 24h Le Mans, 1000 km Monza, 24h Daytona and 12h
Sebring. A number of class victories were also achieved in rally events, Targa Florio and Tour de France.
Around 18 vehicles are known to exist today. Today, the 911 T/R is a sought-after collector's vehicle and can be used in many series, e.g. Le Mans 24h Classic and Tour Auto. This 911 T/R was
equipped with the 906 engine.
In 2024, the vehicle was completely restored by Roock Sportsystem.
Porsche hat nach den Werksferien 1967 für die Saison 1968 ein Sportmodell entwickelt für Profis und ambitionierte Hobbyfahrer.
Es wurden ca. 30 Fahrzeuge hergestellt. Die Basis war eine 911 T Karosserie aus der Karman Produktion, diese Karosserien waren ca. 30 Kilogramm leichter als die Karosserien aus Stuttgart. Daher
der Name 911 T für die T Karosserie und das R für Rallye. Das geringere Gewicht kam durch die leichte Karosserie und den Wegfall von Notsitz, Klappen, Zierrat, Dämmmaterial und den Austausch der
Sportsitze gegen Recaro Schalensitze zustande. Die Innenausstattung, Instrumente und Stabilisatoren sowie Bremsen wurden vom 911 S übernommen. Bei den Motoren gab es die Wahl zwischen einem
getunten 911 S Motor mit ca. 180 PS und einem Motor aus dem 906 mit Doppelzündung und 46er Weber Vergasern mit einer Leistung von 210 PS. Das Getriebe konnte je nach Wahl mit Sportgängen und
Sperrdifferential geordert werden. Sämtliche 911 T/R wurden mit einem 100 ltr. Benzintank und einem Überrollbügel im hinteren Bereich ausgeliefert. Ebenfalls konnten 6 Zoll bzw. 7 Zoll Felgen für
die Hinterachse bestellt werden. Die sogenannte 7R Felge vom 911 R.
Der 911 T/R war ein sehr erfolgreiches Sportmodell, der auf vielen Langstreckenrennen, wie 1000 km Nürburgring, 24h Le Mans, 1000 km Monza, 24h Daytona, 12h Sebring, Klassensiege erringen konnte.
Auch bei Rallye-Einsätzen, Targa Florio und Tour de France, konnten einige Klassensiege eingefahren werden.
Es sind ca. 18 Fahrzeuge bekannt. Der 911 T/R ist heute ein begehrtes Sammlerfahrzeug und in vielen Serien einsetzbar, z. B. Le Mans 24h Classic und Tour Auto. Dieser 911 T/R wurde mit dem 906
Motor ausgestattet.
2024 wurde das Fahrzeug von Roock Sportsystem komplett restauriert.
