I have a 2001 model, 2.0l Selespeed and live in South Africa. I feel that when the rear of the car goes over a bump in the road, it twitches (left to right). The car seems to stay on line, but the twitch is unsettling especially at high speeds and in the wet.
Has anyone experienced a similar problem? And if so, what was the solution? The dealer has checked it out and cant find anything wrong with the suspension itself. The dealer has suggested that I fit Alfa Romeo lowering springs, which may cure the "problem".
I had this problem in high velocity in a curve after another curve.
Now with Koni suspension and Novitec Springs I can do high speed with 200% security.
The original springs in the 147 are too soft, and makes the car jump a lot, go for lower and progressive spring,
but donít forget that the damper is very important too.
I must admit that the ballancing of the car (front:rear) isn't too good when it comes out of the factory.... before lowering the car, in fast corners the rear end would very easily slip out and I had the feeling that I'd be fuc*ed to get it back in line...
However, after lowering the car (nothing altered in regards to the suspension, just the springs) I took her on a race track and she was OK (until I pushed slightly beyond her limits and felt the reaction...)
There just isn't enough weight over the rear tyres (another reason why I keep my MagLite and laptop in the rear of the car)

It's a well known problem of the rear suspension of the 147, at least it's well known in The Netherlands. The great news is that it can be fixed!
The problem is that the bushes of the reaction bars can wear out within 3,000 miles. The only way to see that they are worn out is to disassemble the reaction bars. This is not a weak point of every 147, but on several occasions the bushes have to be replaced. Once replaced the new set will have a normal life time expectance.
its well known that the 147 suspension was set up for 16" wheels and when fitted with the 17s,and therefore an increase in unsprung weight,the dampers fail to return the car wuick enough to the road.Its a complicated subject and one im not qualified to offer advice on,but i uprated my springs/dampers and its cured,
if you are having problems with 16s then i would get it sorted
not sure at all Johnny.An Alfa engineer was intervied in Evo mag and he stated the car was set for 16s,and ran better on then (I have run both and he is definately right in my opinion,on the road that is,on track the 17s are faster,but 16s better balanced) and i also enquired about the jumpy ride and the best guess i got was that the 17s with 215/45 tyres on has increased the unsprung weight enough to maybe cause the problem.As i said,i was advised it was a guess.
And Autodelta didnt have the answer either,they just advise to uprate the springs.Which incidently worked for me.
What are "bushes of the reaction bars" in plain dutch?
I don't know if somebody else has this experience, but I think my Bella doesn't ride as sharply as it did earlier. When I make left hand turns, it sometimes feels like the right front tire is deflated. Cheched tyre pressure, nothing wrong with it. Maybe I'm used to the sharp steering of my Bella and want some more sharpness.....I don't know (but I think I would have loved the steeringwheel to do 1 turn from full left to full right.... ).
And when taking trafficbumps it feels like the steering is "loose" and like there is some margin ("speling") in the steering. I also here a small thud, which I've never heard before! And it's like the car is a little loose in fast corners as well.....
I have to admit that when I came back from holiday, the car was packed and it felt GREAT! Because of the weight on the rear tyres, the car felt more balanced. I have the standard 15 inch Distinctive Alloys, but I think I'll start saving for some 16 or 17 inch alloys!
I don't need no one to tell me about heaven, I look at my son and daughter and I believe.
