Camber shim flash back for the Torsion Beam RColt





Another set of shims.
Camber shims flash back

If you like to read:
/wheel-alignment-notes-tbc.html

One shim created a 16mm shift in toe haha @_@ my maths was wrong on that one.
But the other shim created a 2mm change.
My goal is to slightly increase the 2mm one. Which i hope will give approx 1-1.5 degree in negative camber and 0-4mm of toe change.

                  # Camber Before # Camber After # Toe Before # Toe After
Rear Left   -  #       -3.1           #          -2.9      #      0.6mm   #   -1.3mm
Rear Right -  #       -2.9           #          -2.5      #      4.5mm   #   -11.9mm


After slotting the shims and doing a mild rotation
                  # Camber # Toe
Rear Left   -  #       -3.2       #   -0.9mm    
Rear Right -  #       -3.2       #    -1.2mm
















Front Actual Camber:
So...Using camber bolts on the old coilovers i managed a -1.21degrees at the front.
The new coilovers with camber tops and elongated bolt holes is -3.9degrees
Actual Toe: I have neutral toe settings.
Actual  Caster: 2.9degrees on the left and 3.1degree on the right.
Factory Spec Camber: -1.0 to 0.0degrees
Factory Spec Caster: 2.1 to 3.1 degrees
Factory Spec Toe: -1.3mm to 1.3mm

Rear
Actual Camber:
Previous rear camber is unknown, if you see the sheet provided by bridgestone. I can't make sense of it. /alignment-by-wade-bridgestone.html
At the moment the rear camber ended up at -3.1degrees left and -2.9degrees right.
Actual Toe: Rear toe on the left is 0.6mm and rear right was 4.5mm.
Factory Spec Camber: Apparently factory camber spec can be from -1.8 to -0.3degrees
Factory Spec Toe: -1.3mm to 5.1mm

After my gearbox rebuild i had to go for another alignment so i changed the front camber to 3.4deg
