355 - Ride height difference

B

New member
Just walking upto my car today, and noticed that it looked to be sat higher on the passenger side than the left. Wondering if my eyes were deceiving me, i quickly measure the space between the arch and the tyre on both sides with my fingers (not very scientific, but did the job), and it is sat higher on the passenger side, front and rear.
Anyone had a similar problem? suspension is fine, all working as it should.


Help my leaning 355! lol
 
Please can people remember to put the model type and a brief description of the problem in the title.:cry3:
it makes this section so much more usable:thumbsup:
I've changed it now
 
Sounds like your adjuster gears on your shock absorbers have gone for the sports mode setting, This causes a ride height difference between corners.:hmmm:
 
Had the same problem on my first 355 spider. Had a full geometry check and reset at the dealer and that helped it out a lot.

So, do you mean the actuators are playing up? i have been putting it back into comfort mode a fair bit lately (default setting is sport on mine)
 
Yes i'm afraid so, they are still expansive from Ferrari, apparently the corvette ones are the same and only cost around £125 (each) but I do not know a part number....we're still looking into it.
 
I would not hold your breath, maybe our American contributors can help point us in the right direction?

(we purchase cars needing work:wink3:)

I have a friend here locally that has that info and I will get it for you.

He encountered the same problem and found that the Corvette units did the trick.

Just my opinion ...

A change in the setting of the dampers, as done by the actuators at the top, DO NOT change the attitude of the car. In static configuration, the way the car sit is only due to spring stiffness and their adjustment on the damper body. I would suggest a complete geometry check i.e. front and rear, right and left chassis height as per the manual, and all the angles.

At switch on, the suspension ECU checks the correct rotation of each damper actuator and their end stop. If it is not correct, it will switch on the lamp ... I experienced that with an almost seized actuator.
As far as I know, corvette actuators can not be used directly because they have internally only 1 hall sensors instead of 2 for the Ferrari ones. Motor and reductor can be transplanted but the entire actuator cannnot be used as is.

Agree with Eric, all the actuator does is move a rod inside the damper shaft to adjust the oil flow thro' the valve/shim stack. It doesn't have any effect on ride height.

We had the same debate re ride height at a recent FOC meet. One of the guys was concerned about the issue and tried resolving it in a number of ways (from memory), new springs, I think dampers and a full geometry check (more than once).

Three of us compared our 355s and to a more or lesser amount, all of them were slightly lower on the drivers side (using the same technique as yourself). But that was only at the front.

That was around a month ago and I don't know if he has tried anything else or has just lived with it.

I saw a similar thread on FC (may have been yours) and I do not recall anything conclusive other than the usual suggestions.

Is it a case of "they all do that"? Knowing why would be interesting.
 
Thanks for that Terry.
Its only something ive just noticed to be honest, whether it has been like that for some time im really not sure.
I will get the suspension checked over, and maybe its time for a refresh of the dampers, and check of the spring rates, whilst its in for the service.
Im pretty sure the actuators are working as they should be.

More to the 'To do' list for its annual service........getting more expensive by the day! lol
