BmW AlpinA 2oo2 SportlenkraD (SporT SteerinG WheeL) Auction

Up for auction is a 35cm (350mm) AlpinA 3-spoke steering wheel. Personally, I prefer the 380mm wheels - of course it is all personal preference.  Some definite "patina" on this one both on the spokes as well as the leather, still, it looks to be in good condition.  This one has a "BmW" horn button, last I checked the AlpinA horn button's were still available at a fairly reasonable cost (if the buyer so desired).  Some of these wheels in the past have sold for serious money, it will be interesting where this one ends up....

BmW 2oo2 Grp. 2 HomologatioN PaperS (BmW M12 RennmotoR)

FIA Homologation papers (#5258) for Gruppe 2 BmW 2oo2 race cars for the BmW M12 (I believe the pictured was an M12/6 version), which allowed for the use of twin cam/4 valve per cylinder racing engines in Gruppe 2 racing.  The bottom line is that if you were racing a BmW 2oo2 and you weren't running either a Schnitzer 20-4 or one of these - you weren't competitive.  The M12 series motor(s) ran from the M12/1 - M12/13.  The M12/6 pictured here was manufactured in the period of 1973 (275bhp @ 8500 rpm ) and designed as an F2 motor, of course homologated here for the BmW 2oo2.   The M12/7  came out in 1974 (305/310bhp @ 9600 rpm ) and was likewise used both in F2 as well as touring cars including Gr. 5 32o series.

AlpinA Gr. 2 2oo2 100 L FueL TanK (kraftstoffbehÀlter)

More BmW 2oo2 Gruppe 2 Homologation (#5258) paperwork.  This is the correct paperwork for the 100 Liter (26.42 Gal) fuel tank that the AlpinA Gr. 2 car utilized.  This car raced in a number of "endurance" type races (4 hour and 6 hour events) so having this kind of fuel capacity was essential.  The tank was fabricated out of aluminum and had two locations for remote filling (via Relumit female dry-break).  You see these same Relumit female dry-break fillers on Porsche 911 RsR's and 935's (and probably a host of others). The bottom image is from Sport Auto (1974) and shows the trunk (boot) area of the Alpina Gr. 2 car.  I was told by one of my well versed vintage race friends that AlpinA was able to squeeze out a few extra liters of fuel by filling the tank completely full (including the towers).  Smart, and it makes sense.  You can see that they are conical shaped so that they could potentially hold quite a bit of extra fuel. While my car is quite complete, this item unfortunately didn't make it back across the pond with the car.  If i can find a pair of the Relumit female dry-break fillers not a terribly tricky job to fabricate.  ATL also makes an FIA approved female dry-break filler which would work fine (original part would be better!).  Hard to make out in the picture (bottom image), it appears the majority of the tank is above the plane of the trunk floor.  No fuel pumps visible in the trunk so my assumption is that they had them somewhere underneath (along with the radiator, oil coolers and host of other items).

BmW 2oo2 - BilsteiN GreeN DoT NegativE CambeR StruT ("Bilstein Spezialfederbeine")

Top image is a page from the 1977 AlpinA price list/catalog.  As you will not they had a number of options from BOGE (which I hadn't heard of before - a negative camber BOGE strut) as well as Bilstein.  Any stickers identifying these struts are long gone.  What is left now are the various markings and stampings.  The damper has 150/80 stamped in at the top, which is a pretty mild setting - a good setting for a regularly driven street car.  Other markings are "03 81" which I presume to be the date of manufacture as well as the number 0331101 (part number) and then you can see the splash of green paint.  Down on the spindle, they have been stamped with the numbers "3475" and "3476".  I don't have a standard or Tii strut to compare to but I believe that the spring perch's on these are lower than the standard units. I snagged these off of Ebay a few years back and am saving them for a "future" street car project - In really great shape, though one of the dampers has some damage on it that is going to need some attention.

BmW AlpinA GruppE 2 RacinG StruT (Renn Federbein)

One of the two racing struts out of my AlpinA Gr. 2 race car.  Same strut as used in the AlpinA/CSL race cars. Inverted the same as the typical 2oo2 versions of the strut as the damper threads through the bottom of the strut housing, width of the damper is the same as the (Green/Yellow/Red Dot) struts, however dimensionally different, most of which is in the main body (401 mm vs 370mm).  Most importantly is the settings for the damping - these are set at 440/120.  The "red dot" setting which was one of the stiffest AlpinA offered was set at 220/120.  Of course, you could have Bilstein set the damping to whatever setting you wanted.  These are gusseted for added reinforcement necessary for the pounding the car took on the track.  I found a small amount of moisture in one of the strut housings so I am going to need to send (them both) out for some additional clean-up.  The dampers are fine, although I will probably have them checked while they are checking the other.  Top image is an advert from early 70's from the AlpinA vendor in the UK.  Mounted to that strut is a vented 300mm x 30mm disc brake (two piece with an aluminum hat - again, identical to the arrangement on my Gr. 2 car).

BmW Gruppe 2 2oo2 Hologation PaperS (#5258) SchnitzeR 20-4 RennmotoR

FIA Hologation papers (partial) for the BmW 2oo2 for "Gruppe 2" race cars (#5258) which allow for the use of the Schnitzer 20-4 Race Motor (twin cam 16v, Kugelfischer fuel injection).  All of the specialized parts that were allowed for use in the BmW 2oo2 have similar paper work that both describes and illustrates the item. These were dated January 1, 1973.

MarcH 732 F2 - BmW (SchnitzeR 20-4 PowereD)

Same car that you (barely) see flash by in the video.  This is a March 732 F2, driven by Vittorio Brambilla in the 1973 season, powered by the Schnitzer 20,4 16 valve fuel injected engine.  He was one of Schnitzers' favorite drivers so not surprising to see him behind the wheel of a car with one of their engines in it.  Of course you can always tell one one of these cars has the Schnitzer powered motors in it as the intake will be on the left side whereas the BmW M12 motors as well as the Ford BD/A/G motors have the intake on the right side.
