Re: Wheel Alignment for 155
I had mine done recently after it ate the inside edge of the OSF tyre. Apparently 155s are known for wearing the inside edges - especially if lowered.
The printout from my alignment lists these figures...
Front (each wheel).
Caster 3 to 4 deg
Camber -1.25 to -0.59 deg
Toe -0.03 to 0.03 deg
Total front toe -0.05 to 0.05 deg
Rear (Each wheel).
Camber -1.25 to -0.75 deg
Toe -0.11 to 0.19 deg
Total rear toe -0.22 to 0.38 deg
... These are from a RHD 1997 2.0 16v widebody, but the specs list 155 '91 - '97. The figures were listed by their machine rather than Alfa, so they may not be perfect.
Short answer.. toe should be near enough 0 front and rear. Bear in mind that you will be unable to adjust a lot of these values. I have a bit too much negative camber on the left than the right.
Hope this is useful.
