    To Eric's point exactly.
    Of course I use repro parts.

    Rear seat extensions? Why would someone buy those? To make a rear seat area even more useless?

    It wouldn't have been for Trans Am. 911s were allowed to run in that series as sedans starting in 1967. And they didn't run the 1971 series. I'm pretty sure it was for FIA groups.

    That makes sense. My memory is that the 911 was classified as a sedan without the extensions..

    What's interesting then is whether your need the extension for your FIA HTP. If you want to run that particular class in historic racing.

    Reason of these add-on bolsters on rear seats, only in combination with Recaro Sports Seats:
    Homologation request by Porsche to get again into FIA Group 2 for its 1971 911S.
    (As 1968/69 911T were.)
    Porsche never built 1000 cars in this 911S spec and later abandoned the request as FIA never accepted the changes, still critisizing leg and head room.

    Source: Karl Ludvigsen, Excellence was expected.

    Ps, I wonder if any 1971 911S with these accessories is built in late 1970/early 1971...as once the Group 2 request was stopped, they imo also stopped to supply cars with this add ond, probably by February 1971. Just guessing.

    More than you need to know about Group 2

    The Group 2 racing class referred to regulations for cars in touring car racing and rallying, as regulated by the FIA.

    The FIA established Appendix J regulations for Touring and GT cars for 1954 and the term Group 2 was in use to define Touring Cars in the Appendix J of 1959. By 1961 Appendix J included specifications for both Group 1 Series Touring Cars and Group 2 Improved Touring Cars with a minimum production of 1,000 units in twelve consecutive months required to allow homologation of a model into either group. Technical modifications beyond those allowed for Group 1 cars were permitted in Group 2.

    The British Saloon Car Championship was open to Group 2 cars each year from 1961 to 1965 and from 1970 to 1973.

    Group 2 was the specified category for the European Touring Car Challenge from 1963 to 1967] and the cars were also eligible alongside Group 5 special touring cars in 1968 and 1969. It was the premier category when the series was renamed as the European Touring Car Championship for 1970 and continued to be so until it was replaced by Group A for 1982.

    and

    The Sports Car Club of America’s Trans-American Sedan Championship was contested by Group 2 touring cars from its inception in 1966 through to the 1972 season.

    The SCCA set up Group 2 cars under FIA Appendix 2. The amateur classes were based on displacement: A - 2000cc to 5000cc; B - 1300cc to 2000cc; D - under 1000cc. The Championship series included over 50 amateur races leading to an invitational American Road Race of Champions (ARRC) for the top three sedan class finishers in each of the seven geographical divisions.

    A professional series was a established called The Trans-American Sedan Championship. This series of races was made up of seven professional races at different tracks across the US. The manufacturer with the most points at the end of the series would win the first ever Manufacturer's Trophy. The Trans-Am races, as it became known, ranged from 200 miles to 2,400 miles. The races ran from 2 hours to 24 hours and required pit stops for gas and tires.

    I'll be quiet now.

    Im no specialist on racing.
    What Ludvigsen writes is by/after 1970 Porsche did not got any 911S into Group 2, even they tried.
    I recall reading Porsche was "horrified" that in 70 and especially 1971 Ford Capris RS and BWM 2002tii were driving circles around 911´ and even winning the Touring Car Championships in their classes, Group 2. (71&72).

    Here are the seat extensions in place. I think Michael and Dave will recognize these.

    I seem to remember Bob, the original owner, telling me that someone handed him these extenders when he picked up Patrick at the Factory in Jan '71. This person explained the intended purpose and also mentioned they were not successful in convincing the FIA for entry into Group 2. He also said their 2 young daughters used these in the back seat of the car during their long drives to the Parade. Bob and his wife are pretty short so seat clearance was not an issue.
