156 V6 Veloce

Koni FSD/Eibach confusion

Hi all,

Finally managed to pester the wife enough to let me get some FSD's for my 156 V6 Veloce. I understand that the GTA specific dampers are around £100 cheaper with the only difference being the rear damping rate is slightly different. I guess this is because the GTA has slightly stiffer rear springs.

Checking the Eibach springs though, the springs are quoted as the same for V6, GTA and diesel. I'm guessing then that the difference is so small that the GTA FSD's will be fine for my V6 with standard Veloce springs and any slight increase in rear damper rate will only help to reduce the inherent understeer.

Does this all sound about right?

Re: Koni FSD/Eibach confusion

Not sure about the V6 but for my 147 JTD the FSD's with the factory springs were not the best possible solution, the car was higher then in standard form.

With the Eibach pro-kit springs all is now perfect!!! the ride is much smoother and when you decide to floor the car it becomes stiffer then before....so FSD's really work.

Remember to make the wholes shown in the manual on the FSD...for the rear dumpers!!!

Did you have Alfa sports rate springs (approx 15mm lower) before you changed them

Re: Koni FSD/Eibach confusion

Sounds strange. I didn't think dampers would have an effect on ride height. I know they are the gas pressurised type that will always make the damper extend to it's fullest extent (when not fitted on the car) but I'm suprised it could make that much difference.

I was under the impression that FSD's were designed to work with standard springs. Certainly as mine are the sports springs (veloce)which are a bit stiffer. Don't tell me I have to fork out for new springs as well, the wife may start to put her foot down

Re: Koni FSD/Eibach confusion

I'm pretty sure Koni's are not gas dampers but fluid. The valves inside the damper redistribute the fluid according to driving speed, style & road surface (I think!)
I'm also looking to go FSD with Veloce springs but I wouldn't want the ride height increased or dropped for that matter.

Re: Koni FSD/Eibach confusion

I think they may be gas and fluid, but anyway as you say I don't want a change in ride height either.

Has anyone else fitted them with standard springs and noticed a ride height change?

Re: Koni FSD/Eibach confusion

i fitted them to mine which has veloce springs and didnt notice any ride height change.
Koni also recommend that the fsd's are fitted with either veloce springs or eibach springs for best performance

Re: Koni FSD/Eibach confusion

Yeah, you can't just tell us that without a full blown roadtest report

Has it stopped the bottoming out?
Is the ride more comfy/less crashy?
How's the handling now?

That sort of thing.......

Re: Koni FSD/Eibach confusion

Ride hight shouldn't change but i'd say the oem sports springs would pale in comparision to the eibach pro springs which are under $200.

sweet talk the wife into getting those.. they will only drop the car another 1.5 cms.

Re: Koni FSD/Eibach confusion

my jtd was on the normal standard factory springs...my friend with whom we tune together our cars and remap them....on his old 156 with the alfa sports springs didn't have the problem with the increased high!!!

So you might expect increased right high only on normal factory springs.

But comparing the way the FSD did work on his old 156 (alfa sport springs I think they were Eibach as well) and my 147 with before and after I fitted the Eibach pro-kit springs...

FSD's work the best with the eibach pro-kit...maybe that is the reason why now Koni are even selling them in package with the eibach springs.

on my car I also have powerflex everywhere...and together with the Q2, FSD-eibach the car is now what Alfa should have made as a factory tuning version...it is perfect on both highways and it is a LOT of fun on county roads...especially mountain passes, that I go trought very often.

Yup no more bottoming out, i have mudflaps fitted to mine and they were constantly hitting the ground before but now this hardly ever happens!
the ride is also much better, though still a bit crashy over very rough surfaces, though i think this might be down to my badly worn bushes...
the handleing is great, stays very flat round the bends, the car can also handle the **** roads around my area much better, even with that big 2.4 lump
Also afaik the spotspack/veloce springs were just eibach's painted black?
could be wrong though

Re: Koni FSD/Eibach confusion

Sounds good. Yes I thought the sportspack springs were Eibachs as well.

I'm sure the Eibach pros are better but I think on the sportspack cars it's the dampers that cause the main problems. I also don't want to lower my car any more as on country lanes it can scrape the under-tray on the 'verge' down the middle of the road already.

I wonder if anyone like Larkspeed etc, who seem to be among the cheapest for FSD's are likely to have a January sale.

Re: Koni FSD/Eibach confusion

Get the GTA FSDs, it saves almost enough to buy you the Eibach Pro Springs outright..

Thats what I did

GTA-spec FSDs on a non-GTA V6.

Re: Koni FSD/Eibach confusion

To be honest that is what started my confusion. The V6 and GTA have different dampers due to different spring rates but if you uprate the springs to the Eibachs then the springs fit both models.

I can't really justify the extra £100 odd for the springs as well, justifying the £400 for the dampers is involving serious bribery as it is, shopping trips etc......

Re: Koni FSD/Eibach confusion

I'm as confused as you Andy. I'm not sure which kit to buy, but my logic is if the kits are different because the spring rates on the GTA are different in oem why don't they make different kits for Veloce springs as they are different than standard & then another kit for Eibach Pro's as they are different again.
I'm tempted to buy the GTA kit aren't you?

Ah, but you only have them on the front, so we don't know what effect the rears will have

Re: Koni FSD/Eibach confusion

Yes I'm very tempted with the GTA spec dampers. The difference is probably so small that you wouldn't notice. I wonder if anyone has fitted the GTA spec to a V6/diesel without using the Eibach pro kit???

I think it could be a race to find out, but neither of us want to come first in case there is any problem.

Because the rear end of my car is massively different to that of a GTA.. :hmm:

I'll have the rears on in January I'd imagine, the garage is a bit full at the moment as we are working on my brother's escort then getting my grandad's vectra through its MOT, then probably stop for Christmas then do the rear end of the Alfa. I'll let you know what they're like then but to be honest I doubt you'd notice the difference between the GTA shocks and the non-GTA ones.

The reason they made some GTA specific dampers is cause the GTA boys weren't happy buying shocks that were universal with the "lesser models". Its a marketing decision, nothing else. Thats what I reckon anyway and I'm taking advantage of it. The reason the GTA dampers are cheaper is purely because they are sold more often, and economies of scale have forced the prices down. Not many people can justify £400-£500 shocks for their 156s, but the GTA boys can..

Re: Koni FSD/Eibach confusion

Think i read somewhere that the gta FSD's are slightly stiffer than the standard for some reason
Though as Pud says its not like theres much difference between the back of a gta and a standard car!
Also the main problem with the 156 suspension comes from the front,
especailly in the v6/jtd versions as they are so heavy and always bottoming out/bouncing around everywhere.
I wouldn't be inclined to worry too much about the back...

Re: Koni FSD/Eibach confusion

Anyone know how much lower the Eibach Pro's are than the Veloce suspension?

I wouldn't mine going about 10mm lower but I'd then have to think about the alloy sump guard which is supposed give up to 40mm extra clearance (10V one modified by taking a couple of chunks out)

Mine looks about the same as most Veloces on 17" wheels, if anything slightly lower but not by much., I doubt there'd be much in it if you parked mine side by side with another Veloce. The ride height looks fine at the front, more like "the low side of normal", than "low in a nice but slightly impractical way", if you get what I mean.

Strange though, it still seems to corner just as flat as when I was on the coilovers, even though there is certainly more bounce in the suspension than there was before. Certainly think these FSDs are magic. Looking forward to getting the rears done, hope it doesn't raise the arse too much though it looks spot on as it is now.. :hmm:

Re: Koni FSD/Eibach confusion

The cheapest I've seen a set of FSD's for my 2.4 JTD sportwagon is £499 in vat and P&P and that's from koni direct. Anybody know of somewhere cheaper?

I have a leaking rear damper, and I can't by just a rear set of FSD's and I've been quoted about £90 for standard dampers so I may as well get the Koni's as £90 sounds a lot for alfa dampers that will go early again. I intend to keep the car until it dies and it's only done 58k miles.

That's probably near the best you will get, Larkspeed is £506 with delivery. How about the GTA version as discussed on here for £84 less?

£493 inc VAT & delivery @ www.koni-suspension.co.uk (which isn't KONI direct but POTN) or GTA version £402
