Hi All, I have major negative camber on both rear wheels on my 1980 S2. Where do I start to adjust / fix this.
All inf o welcome, Thanking You, PAUL

Before attempting to "fix" the "issue" we shoudl ask some questions.
have all other dimensions been checked and found to be in tolerance (including ride height front and rear while weighted, rear toe etc)?
Is the gearbox sound (I recall the s2 uses the gearbox as the top link like my Europa)?
What suspension set-up do you have?
Please confirm that by negative you mean the tops are further in than the bottoms of the wheels, and then as Peteyg asked, what are the readings currently?

The upper and lower arms are very different in length (upper is your drive shaft for s1 & s2 IIRC), so when they are approximately horizontal it gets the wheel to the correct camber, when the body raises you end up with what appears to be a lot of camber. When the body is lower (relative to the wheel) you get lots of camber camber.
If the arm length (either top or bottom) is too short at the top I'd suggest that would be the drive shaft Universal Joints being incorrect or the bearings in the output of the transaxle are in need of adjustment.
The change in body weight of the car (engine etc) can cause the body to rise, so can exceptionally strong springs. Similarly, lowering the car by the use of shorter/ weaker springs would give a lot of camber.
First thing, is when the car is assembled, don't tighten the pinch bolts on the suspension. Load the car to the correct weight and measure the height from the floor to the lowest pint on the hoop of the rear frame. It's not normally adjustable (adjustable spring seats and different spring will adjust it). It's possible a previous owner has altered it by fitting different components.
If the ride height is correct (or there about) and you have a reasonable rear toe in, then suspect a previous owner of having swapped some parts.
