Hi Guys,

Glad the forum is back. Don't know where I'd find the answers to the many question 155 owners have if it disappeared !

I recently got new tyres for the front wheels. I expected the handling to be changed maybe a bit, but it seemed to make a bigger change than expected.
I thought that it might be worth getting the tracking checked, what with having new tyres and looking to prolong their lives, and maybe this had an impact on the handling.

I went to a garage with one of these laser alignment tracking systems. I watched the guys as they where doing it and you have to feed in the model of the car and then the computer tells you to adjust it this way and that !
My problem with this was that the computer only had 2 Alfa 155 models. One i think was a Q4 (memory lapse), and another model with seemed to span several types.
I would have expected that the tracking figures would be different for all or most of the models. My car is a 97 2.0 16V Sport, and according to the computer should be set up the same as all other 155's bar the Q4.
Is this right ?

The handling still seems off to me, but now I am beginning to doubt myself, and maybe it is all down to the new tyres.

I don't think its a suspension problem either, as the car had its N.C.T (National Car Test) yesterday and passed (surprised me !).

Any thoughts ?

Ger.

I would be very surprised if Widebody 155's had the same set up as earlier models...

Hi
I wouldn't think so. I would be off to my local agent and ask nicely for the specs. Unfortunatly, unlike Lancia, Alfa don't seem to out the allignment specs in the owner's manual.

Hi

A friend of mine took his 146 to a tyre alignment place armed with figures from Alfa, they were different. We never found out who was right. You would imagine the laser alignment machine is calibrated with figures from Alfa, wouldnt you???

I too found a major difference in handling when using new tyres. I put it down to the extra tread "moving" when they are new. Does that make sense??? :confused:

Thanks for the replys guys,

wrinx, it all makes sense !

A_Möller, I can't find your email address to send a mail ?

Do the figures differ for each model 155 ?

Thanks,
Ger.

2.0TS 16v Tracking straight from the Alfa Manuals.
All in Italian I`m afraid...
(% means degrees)
ROUTE ANTERIORI (Front I think)
Campanatura: +20` -20`
Convergenza: +1 +-1 mm
Incidenza: 3%10` +-30`
Asseto: -20 +-5 (Super) -35 +-5 (Sportiva) mm
ROUTE POSTERIORI (Back)
Campanatura: -1% +-15`
Convergenza 0.5 +-2 mm
Asseto: -10 +-5 (Super) -25 +-5 (Sportiva) mm

What more could you want :)
- apart from a translation?

I've got the English version.
This applies to all vehicles except Q4 . It doesn't matter if they are wide body or not.
Toe in 0 +/- 1mm
Camber 0 +/- 20'
Caster 3deg 10' +/- 30'

These are unladen.
Caster & camber are non adjustable

Hope this is of some help. :)

Thanks Mike !

That answers my question.
Every model the same except Q4.
The computer on the laser aligning device was right after all !

Difference in handling must be down to the new tyres.

Thanks again guys...

According to Chris's post, it looks like the Super has a different setting. This would apply to all non-Sport models.

Henry

The difference on the Super refers to a vertical measurement between two parts of the suspension,, hence the 15mm difference which is the difference between a sport & super suspension ride height.
:p
