Sorry to be back on the well-worn topic of springs, but I thought this info might be useful. Need to start by mentioning that I coat all my suspension components (including the springs) with black Waxoyl annually. Been doing this for years - long before the spring crisis broke.

Anyway, having read all the dire warnings about corrosion, I thought I'd better change my springs. Got a set of Lesjofors (front and rear) and decided to fit KONI Sport dampers at the same time.

The job wasn't straightforward (what job on a car ever is?) thanks to one of the bolts holding the front strut being seized solid in the lower casting. I would also support Deck's advice on having your front springs compressed at a local garage. Tried to do this myself, but the Stilo springs are so long, for me it proved impossible. Even the garage struggled - it took them two hours! However got there in the end. So what did I find?

First disappointment was the Lesjofors springs. Front ones were OK, but the rears were at least 2" longer than the FIAT springs. Even after settling, the rear of the car looked like a 4x4! In the end I swapped back the original springs (you'll see why I could below).

When I examined all four springs I had removed, I could find absolutely no evidence of corrosion whatsoever - not a single blemish. Three cheers for Waxoyl I say!

Best result though, was the KONIs. They are sooo good! I am delighted with what they have done for the ride and handling of the car. Previously the ride was really 'wallowy', inspiring no confidence. Now the car feels taut, corners flatter, yet still has an excellent ride quality - thoroughly recommended.

Thanks to the guys who wrote the Guides that proved invaluable when doing this job!
 
It's weird that that the rear springs were so much longer, they're meant to be the same as Lesjofors take dimensions off the originals so it sounds like the wrong springs. Still, if your rear springs are in good nick then that's the end of it. Like me, are you sleeping better now?:)
 
That's your look out for living too near the sea!:)
Rears looked ok on external visual but I wasn't so worried about them as the fronts.
Fronts feel fine after spring change, same height springs so no real difference, less soggy though and no more creaking:D
 
I think we've proven between us that there's no direct correlation between springs & creaking ;)

My new Pi's creaked more than my old springs (which basically didn't).

Given the new springs the Waxoyl treatment (mainly on the rubber inserts) and they seem to be quiet now (y)
 
How much did your Koni's cost, and did you go all round?

Yes, all round of course. I'd never bother with changing one end only. KONIs aren't cheap, but they are a quality product, adjustable and carry a lifetime warranty. £85 +VAT each for the fronts and £70 + VAT each for the rears.
 
I was referring to the Konis Vs Eibach Damper comparison, not the springs ;)

Ooops! Sorry for the misunderstanding. Main difference between Eibachs and KONIs is that the Eibachs aren't adjustable. But if you're fitting Eibach springs too, then arguably they will be better matched (though you could also argue any mismatch with the KONIs can be countered by adjusting them).

Incidentally, Eibach dampers are not made by Eibach (I think they are Spax). Eibach concentrate on what they do best - making springs - and KONI concentrate on what they do best - making dampers (KONI springs aren't made by KONI either).

Awesome, cheers dude.

I've got springs (GMax) but couldn't afford dampers at the same time, looks like it's going to be the Konis...
 
I'm sure you won't be disappointed. Incidentally, the KONI part numbers are:

8741-1449 SPORT (front)
8041-1294 SPORT (rear).
Fascinating post there Yellow Peril (y)

So you're saying the new shocks actually stop body roll on quick direction changes even when used with standard springs (obviously they can't impact on long curves because at the end of the day they’re only shock absorbers)
 
Yes that is what I'm saying. Here's a quote from KONI's website (my emphasis):

KONI’s Sport shock absorbers are designed for drivers looking for a sporty driving experience. These products focus on exceptional road-holding combined with an acceptable level of comfort. Its characteristics include responsive steering, reduced body-roll and limited body movements. Externally adjustable shock absorbers make fine tuning even easier.
