One to Buy: 1975 Porsche 911 3.0 Carrera RSR Kremer Spezial (SOLD)
By the late 1960s, Erwin and Manfred Kremer’s eponymous Cologne-based racing team was arguably the number one privateer Porsche outfit anywhere in the world.
Established in 1962, Kremer Racing quickly gained a reputation for their superbly prepared Porsches. The firm also began to create their own update programme which gave Kremer-run cars an edge on the rest of the field.
For the 1975 season, Porsche had planned to introduce the Group 5 935 and Group 4 934, both of which were based on the turbocharged 930. However, the two new cars were ultimately delayed which resulted in the existing 911 3.0 Carrera RSR having a second season at the top level of competition following its 1974 debut campaign.
Kremer ran a trio of 3.0 Carrera RSRs during the 1975 season, one of which – chassis 005-0004 – is currently on offer at the Canepa showroom in Scotts Valley, California.
005-0004 was one of four RSRs built up from bare bodyshells by Porsche approved customer teams for 1975. Kremer ran it in the colours of Wally Jeans for Cees Sievertsen who primarily contested the domestic Deutsche Rennsport Meisterschaft (DRM).
Sievertsem was a consistent top ten finisher in the high profile 1975 DRM series. His best results were a brace of fourths at Hockenheim and the Nurburgring while he also picked up a couple of wins in non-championship GT races.
Today, chassis 005-0004 is offered in superb restored condition and comes complete with its original ONS Wagenpass.

5-speed transmission
Fuchs 10”x15” front, 14”x15” rear center-lock wheels

First place at Diepholz and Hockenheim in 1975
This is the Wallys Jeans sponsored RSR built by Kremer Racing and raced primarily by Cees Sievertsen in 1975. It has extensive European racing history and many podium finishes, including a first-place finish at Diepholz and Hockenheim. After its tenure with Kremer in 1975, the car was sold to privateer Heribert Asselborn, who raced the car for the majority of the 1976 season. At the end of the season, 005 0004 was sold to racer Georg Feiberger. He finished off 1976 in the car and then sold it to fellow racer Karl-Josef Römer. The car continued to race at the amateur level in Europe for a number of years.
It turns out that after being separated from its components, 005 0004’s original chassis was built up once again, and rally/ice raced in Iceland. It was discovered in the late 1990s by some rally friends of American Porsche racer Joe Cogbill with its original parts still attached, such as the front suspension, shock brace, and steering, which is unique to the RSR. Joe offered the chassis for sale to fellow Porsche enthusiast Charles Coker Jr. of 356 Inc. in Nashville, TN, who then imported the chassis from Iceland to the United States.
Meanwhile, Michael Foveny of Munich, Germany, purchased the replacement chassis car in 2002 from Bo Strandell, a Porsche dealer in Helsinborg, Sweden, who had experience fielding team at Le Mans, along with 005 0004’s original racing logbook (ONS Wagenpass). From 2003 to 2004, Foveny set about a complete ground-up mechanical and cosmetic restoration of the car at Roitmayer in Munich, Germany.
During their restoration research for 005 0004, the Roitmayer team heard that the original chassis was actually in the United States and contacted Coker. After an agreement was reached, the original chassis was shipped to Germany, where Friesinger Motorsport performed a complete restoration of the original tub. Once the tub had been finished and painted in the proper Wallys Jeans Blue, it was sent back to Roitmayer for reassembly.
All suspension components were crack-checked and restored before refitting to the chassis. The original numbers matching the 3.0-liter engine and transmission were rebuilt mechanically and cosmetically. Once Roitmayer had remarried the original chassis to its original parts, the replacement chassis was destroyed.
Whole once again, 005 0004 soon returned to the track and raced in the Le Mans Classic in 2004 and then again in 2006. It also has seen action in an Italian street rally and at Spa.
In 2008 the car came to the United States. Its new owner enjoyed the car at several historic events, including the Rennsport Reunion IV and numerous showings at the Rolex Monterey Motorsport Reunion. The RSR’s new owner was in Europe, where it competed in multiple historic races and had an engine refresh in 2018.
