Suspect could be the suspension on hard tyres get it checked.
How to correct body roll of a Linea!
Stephen, i read the issue. Body roll doesn't have any technical definition as such but generally associated with sharp turns where driver (& even passengers) have to struggle to keep his body in rhyme with the car (unlike when it is driven straight). For instance, you are thrown to left of your steering wheel if you tilt it right. It's driver/Passenger's body that is refrred as "rolling".
Though it is physically impossible to have zero body roll due to laws of physics like Gravity, centrifugal force & friction, good cars have it minimum. What i read from some of fine driver friends @TFI that even after enhanced GC, Punto/Linea's body-roll is intact like earlier models. What i could understand is "just bumpy ride". I think you need to elaborate it. Anyways, if you are referring this body roll which i just typed, no TASS or Technician can help this. It's particular for a car & can't be corrected until it's whole platform (Chassis) is revised!!
A stiff suspension does not give a body roll. A softer suspension does it. From my test drives of new models i can say that the suspensions are having a bit more travel than older ones. So maybe there is slightly more movement sideways as well as pitching in new models, but it should be as bad upto people getting nausea.
FIAT ruined their cars with such an awkward GC, sort of an over-reaction by FIAT to the articles in magazines. Punto/Linea never scraped from beneath more than any other car in it's segment. It doesn't take too much IQ to raise a question. I hope FIAT won't react to every tom-dick & harry in future. However, They should correct it in their 2013 models & give an option to all 2012 owners of changing of their suspension at minimum/subsidized cost. With the GC that FIAT car's have at present, looks like they can't wait for JEEP to come this side of world.
after so many replies i'm still tryign to know the " Body Roll " :confused
i think this is more experienced in 16 wheel truck .
Obviously it's due to stiffer spring setup what i concluded from owners of 2012 models. It certainly is a genuine flaw for the people who don't like sportier set up because they hardly need it. Majority doesn't & it's perfectly understandable in city conditions! 2010-2011 models were best of both the worlds. We should trust them as they are the one who drive them in routine. So many people can't be wrong for stiffness part & FIAT should do something about this. I wonder if our friends escalated it to top mgnt. A repeated complaint would definitely ring the bell.
Here is a short video related to body roll.
Body roll is the degree to which the vehicle body rolls when driving around the corner. Its like while taking the curve, the wheel axle is horizontal to the road while the body alone tilts to the side due to centrifugal force. I think Dr. Stephen is referring to the bumpy ride. Its common in the vehicles with stiffer suspension. When the wheel hits some bad patches on the road, due to stiff suspension and low speed, the entire car will be shaken. It means the shock-absorber has not come to play and the shock has not been absorbed fully and sent directly to the body.
You can consult some suspension specialist or simply You can go ahead with suspension sets from 2011 lineas.
Yes,this is due to the new spring+ shock combination which is not a properly tuned one as in the case of 2011 's .I am concerned with the pitching of individual wheels when they move over uneven surfaces at lower speeds. This actually makes an up down shaking along with a little lateral shaking. I f such a travel time is more, the passenger, especially at front seat will be really in trouble. Especially elderly people.2011 model has properly tuned spring+ shocks combination (This is nothing to do with GC-I think so).For 2012 the tuning is not perfect. FIAT has to select proper combination through trial &error method or proper R&D.I think (My belief) they have done the increase in GC without proper ?.Going back to 2011 GC is not appropriate for Indian conditions.185 mm GC of 2012 is also on the higher side.,175 mm is more than enough.<O</O
I request experts in this area to give a way out of it or (FIAT should give a solution.) Some minor niggles (not serious-can be ignored) are also there. If these are solved, Linea will be a wonderful car.Also if 2012 owners post their experience in this ,it will be a help for others also.<O</O
What would be the best way of raising a complaint; atleast letting them know?
When Fiat's were launched,people complained of Low GC,and Fiat fixed it by altering the existing suspension by replacing the shockers and Springs.To make sure,they do not turn into sloppy handling cars,they made the springs stiff,with the increased COG,body roll increased as expected,and ride Quality suffered due to stiff springs and shockers.Guys you win some and lose some.If you want your car to ride better with less body roll revert to existing set up.Those who want GC can stick to the newer set up.No point in going and complaining about,it does not make any sense.
I may be wrong but i am pretty sure Fiat is not selling GC upgrade kits anywhere else apart from India.
I love the pre 2012 suspension set up
