ALPINA

Fixed Camber Plates at Marathon de la Route

 

Good observations by Tommy, The inboard orientation of the upper strut bushing is indicative of the  use of fixed camber plates.

 

Again, this photo was taken in July 1967. This dating raises the following questions:

-  would Koni Special D inserts in standard strut housings have been

used?

-why would the Boge Alpina strut, an example of which is pictured in the ALPINA - FAHRWERKS - TEILE ad not have been used?

-or does the Alpina Boge strut lack built-in negative camber and is used with fixed camber plates?

 

-or perhaps the Alpina Boge strut was not yet homologsted for FIA / ADAC sanctioned events?

 

 

I'm just guessing but do not know:

1: In my September 1967 Pricelist I only find the "Koni Spezialfederbein" (red adjustable Koni as shown on the Hobby cover). I Actually don't know if this alreday had build in negatice camber.

2: The "Boge Speziafederbein" appears in my January 1968 Pricelist for the very first time (so half a year after Alpina raced the Marathon de la Route in 67). I don't know how many degrees this Strut got but im sure the only reason for this strut is a) maybe a lowered spring-table and b) build in negative camber! Because damper wise the Boge Strut looks pretty much serial?!

3: The "Bilstein Spezialfederbein" (Upside Down) with the parts Number 11441300812 appears on a technical drawing in my Archive that is dated September 19th 1968.

Build in the Strut I'm pretty sure that 1.5° negative camber are the maximum to get without getting problems by the wheel touching the strut on the inside. So as far as i know: If you want more then 1.5° negative camber you needed to get that from the top bearing.
 
This is the reason why I added another 5° by using fixed negative camber bearings.

Those all could be reasons why Alpina had the fixed negative camber plates on the 67 maratothon de la route car as well.
As @BarrettN 's car got fixed negative camber bearings as well it would be very intersting to measure the "in total" negative camber on his car...

As I did a couple of pictures for the insurance, I just wanted to share them here. Even though they are not highclass photos they show pretty good what bits and pieces the car comes with...
All bits and pieces that say that they are Alpina are original Alpina parts, i tried to keep the rest as period correct as possible an and my aim was to use as much unrestored parts as possible. Some of them were only possible with the help of my good frien @uai
I'm pretty sure that there are just a hand full of cars out there that got so many original Alpina parts mounted...
Can you spot them all or shall I make a list? 😁

Not visible in the Pictures:

AO, there’s so many unusual-to-me bits here and there. (And I’m not that tuned into the base 1600/2 differences to know stock from Alpina on many). And it’s such an amazing time capsule. Wow!

 

Ok, just four Qs to start:  

• Can you discuss your header? Looks like a 4:1 with some big tubes for a 1.6l…

• What are the notched sections in the front of the flat headlight covers sheet metal for? 
• Wheels are sweet - details? Model, width?

• What does that really long pull-knob on the right of your dash binnacle do?

 

 

And one other thing for all of you, relevant to the just earlier discussion on Alpina struts and camber mods…

 

When I was looking for 02 Alpina engine bays and interiors, I came across this:

Found on this car.

 

I’ve never seen those strut top pieces before. Are they also Alpina bits? Is it just a metal dust-cap replacement or does It look like they are for performance in some way? There’s no apparent camber benefit visible…

 

Thanks,

Tom

Hi Tom,
Question N0 1: you mean the exhaust? First of all: the Engine is a 2l engine with forged pistons, bigger valves and 300° Alpina cam. (and a lot more, so basicly what was called an A2S or A3 Engine) with around 160-165 Horsepower.
The Exhaust header is a serial BMW M10 2l Manifold that leads into the Alpina specific Downpipe / Y-Pipe (2 in one).
Hope that was what you were asking

Question No2: after reading it again and again: I dont't get it... could you bring this question into differnet words? 😄

Question No3: Wheels: its the so called "Alpina Lochscheibenrad" (Alpina Steelwheel) produced by CMR and available from around 67 in 5,5x13", fitted with 165HR13 Michelin XAS Rubbers

Question No4: the really long pull knob on the right side is for the windshield wipers, this is the serial early postion of this kob, the extension were tipical for that period in cars fitted with fiexed racing harnesses to keep the lights- and wiper-knobs in reach of the driver.

That's it so far.

Now a quick list of the modifications done on this car:

- 2l sports engine with forged pistons, hemispherical combustion chambers, with larger valves,
300° camshaft, completely reworked crankshaft, lightened and machined
connecting rods, lightened flywheel and clutch and carburettors Weber 45DCOE 9

- Rear axle with 40% limited-slip differential
- Shorter ratio steering gear 1:12.8
- ALPINA suspension kit consisting of:
- ALPINA special spring strut with Bilstein upside down damper,
- lowered spring plate and 1.5° negative camber
- further 0.5° negative camber due to repositioned strut bearings
- ALPINA suspension springs front and rear, progressively wound
- rear shock absorber Bilstein Upside Down with Unibal joint
- adjustable stabilizer front 18mm and rear 16mm
- inductively hardened axle shafts
- drum brake 230mm rear
- ALPINA brake discs 20mm internally ventilated front
- ALPINA light alloy brake calliper 911S (together 5kg lighter than the cast callipers!)
- preload rings
- closed rear axle swing arms
- Tires Michelin XAS or Pirelli Cinturato CN 36 in 165-185, optionally: on
- ALPINA perforated disc wheel (CMR) 5.5x13“ or
- ALPINA light alloy rim bimetal (Borrani) 5.5x13“
- complete rally exhaust system, consisting of front and rear silencer
- ALPINA Y-pipe
- ALPINA competition tank 90l, to be filled through the trunk
- Bendix electric fuel pump
- ALPINA roll bar
- ALPINA leather steering wheel 350mm or ALPINA wooden steering wheel 360mm

and rear axle oil temperature in Metal console
- ALPINA lettering, aluminum for valve cover and rear panel
- TRICO racing windshield wiper blades

Oh my god? Did I really forget something? 🙈😹
What is it? (okay, Marchals, original BMW Cocomats and the longer Neue Klasse shifter are not listet, but what else?)

[JohnP_02]

No no no I was kidding! That is pretty much everything!! Wowza!! 
 

The fact that most of those pieces have not been restored is really amazing. Well done! Hope to see this thing in person someday.

Hahah... i think the only thing I could ad are the rear disc brakes...
and: if you ever come to Munich, you are more than welcome to take a ride!

Ok, NOT a 1600. A2S/A3 were the top carbed models, no? Sweet specs!

Yes, the downpipe. Uli has mentioned the great performance gains with those homologated ones on the stock manifold. So that’s the Alpina one, and size is now also explained. Thx!

I can do 1000 words worth, a pic!

 

No.3   I didn’t know about those steelies. Very nice!  They looked wider to me, they fit so well..

 

No.4  Knob extensions! Makes complete sense now.

 

Thanks man! Your mods list is extreme! Love it.

I can't see anything special there compared to e.g. orange car above. Are US cars somehow different because of the different headlights?

Michael also wears alpina underpants.

In some Racing classes you have to run standard strut bearings.
So some guys made rosejointed strutbearings that look alike standard strut bearings. - I think the ones above are an attempt to achieve the same.

Tommy, I’m probably seeing nothing, but I have rectangular holes in that headlight cover flap, as does the orange car above.  Maybe it’s just a 1600 thing, but AO has an additional notch in the front of his rectangular cutouts. ( the cutout usually sits about 1” inward from the front sheet metal, but his extra notch takes it right up to the front fascia.)

 

Maybe for attaching something there? Like what? Ha!

 

Again, it’s probably just a normal 1600, I’m just not familiar with. Of all the other interesting bits in this car, why’d my eye pick up on that? Lol

You see somthing that isn't there. It's just the sheetmetal nut that is for the grille Pos 10 in the pic
