Only for the 9N GT, with the PD130 unit. For a PD100 9N Sport, they'll have the wrong spring rates, as the PD100 unit is lighter than the PD130.

Really? In what way could it be lighter? Surely it's fundamentally the same engine, other than different turbo etc.

If i remember, that Polo doesn't have the 6 Speed box, which adds to the weight.

Yeah but your talking a couple of kilo's - I doubt very much they'd go to all the trouble of manufacturing different springs for every different varient.

For example :

Spax list the same set of lowering springs for the 1.4TDi and 1.9TDi Fabia II - that's missing a 1/4 of an engine!!

You'll find this if you do a search on here, or ask any of the suppliers of suspension equipment for either vehicle. The PD100 engine weighs less than the PD130 unit. Fact.

And yes, you have difference in gearbox as well. Look up the difference in weight between a PD100 9N Polo and a Fabia vRS if you like. Try Automotive technical data and specifications - Carfolio.com specifications - Carfolio.com car specifications pages for stats.

By all means fit them- but they won't be the right spec

Boing boing boing....thats what they'll do ! :thumbdwn:

Like I say manufacturers of uprated suspension such as Spax sell the same part number spring kit for both the 1.4 and 1.9 TDI versions of the Fabia.

Other than the fact there is a different curb weight they will physically bolt onto the car.

But we're not talking about, or indeed comparing the 1.4 and 1.9 TDi units are we? We're talking about two variants of the 1.9TDi, the PD100 and the PD130! I never said they wouldn't bolt on, they're compatible in that sense. It's the spring rate that won't be right.

Just don't say we didn't warn you

Steve

But surely there is a greater difference in weight between the 1.4 and 1.9TDI unit that there is between two 1.9 TDI units? My arguement is that if they sell the sames springs for two cars that have an engine that is very different in size and weight then a marginal difference in weight isn't going to have much impact.

We're not talking Formula 1 cars here, we're talking normal every day road cars.

I do appriciate your input though and I will take it on board - i'll give you some feed back on how the car drives etc once they are fitted.

Good luck with it. All I'm saying is the likes of Eibach do two different springs for the PD100 Fabia, and the vRS for example. They do this for a reason.

Steve

Although slightly different, the same practice applys to those who have tried Golf/Bora springs on an Octavia. They just cant cope with the extra weight, and they either start to sag, or bounce around.

Neither is a good result.

I wouldnt even bother writing a reply. Phil obviously knows more then we do.

I say you try them and see the results for yourself :P

Well I have got a HND and Degree in Automotive Engineering. I've spent the last 7 years working as a Design Engineer for several Tier One Automotive Companies and my weekend toy is a 600bhp Skyline engined 200sx which I built myself . . . so chances are your right.

Good on ya

I am just a sweeper upper :(

I know nothing about fabias either.........

I know one thing tho, spax are ****e, their spring rates are all wrong...... do you how many different spring rates their are for the polo 9n?

Look at the different part numbers on etka for these........ should give you an idea.

I totally appricaiate what people are saying with regards to cars having different spring rates but if you go on Awesome GTI's website, they sell a suspension kit that is said to o.k for the 2.0 petrol, 1.9 SDI and 1.9TDI - they must vary in kerb weight?! So are you telling me that they are in the wrong??

As the springs that come with the kit are uprated they will have a higher spring rate anyway.

The worst case senario will be that I fit the kit and the car does as you say, in that case i'll replace the springs with something 'more suitable' but for the money I bought the full kit for i'm happy if I have to do that.

I had spax springs on my Corsa.

The ride was awful, worse than the AP coilovers I have on the Fabia.

That's probably bescause you were running standard dampers.

O.k guys - lets just drop it, I think we've both had our say on the matter. This has gone totally off topic from the original post after a simple question in relation to it.

Some interesting thoughts and information has been posted up though.

We're talking about two variants of the 1.9TDi, the PD100 and the PD130! I never said they wouldn't bolt on, they're compatible in that sense. It's the spring rate that won't be right.

Been there done that. In fact should have some eibach Pd100 springs knocking about somewhere

Beleive me the spring rates of the PD130 and PD100 are different and will have an impact. If you fit spring rates for a PD100 onto a PD130 car you end up with a face down *** up... In fact I recon the standard vRS springs are stiffer than eibach PD100 springs.

1.2 1150kg

1.4 1155kg

1.4 Auto 1185kg

2.0 1200kg

1.9 SDI 1215kg

1.4 TDi 1220kg

1.9 TDi 1235kg

1.9 TDi 130bhp 1315kg

Found this list on a VAG website relating to Fabia weights.

What we're talking about here Phil is that you very obviously and arrogantly ignoring advice from other members, given in good faith by those who know what they're talking about. You bring up the case of Awesome. If you actually ring up and speak to Sarah and go for a decent brand of spring (Eibach, H&R, KW) you'll find that there's a specific model number made for the vRS. That's made for a reason and it's there so that you get the best aftermarket product for your car.

So when you ask "So if I buy a suspension setup for a 1.9 TDI Polo 9N it should bolt straight onto my VRS Fabia?" genuine, regular members of this forum will tell you 'no' - and with reasons as to why it won't be the most suitable product for your car.

One of the main benefits of a car forum, and the members that frequent it is that you're able to easily tap into a resource and avoid mistakes that others have possible made before. But of course, whether you follow it or not is totally upto you. I couldn't care less how qualified you are, and in what arena. That's secondary to being able to follow good advice.

And this is the last I'll be saying on this matter.

Steve

I'm not ignoring peoples advice, i'm just trying to get my point across.

Like I said in previous posts I do appriciate what your saying it's just I don't believe it's quite the case due to my previous experiences.

We're all entitled to our opinion. I was just demonstrating mine. I'm not saying your option is wrong, and I've said that if I'm wrong then I'll change the springs.

At what point have I been arrogant?

In summary they will fit but they were not designed to cope with the EXTRA kurb weight of the car and hence may cause problems with regards to the normal working of the suspension kit under normal conditions.

I'm not saying your option is wrong, and I've said that if I'm wrong then I'll change the springs.

This is exactly what we're trying to say to you...

They will be wrong !

Save yourself doing twice the work, and buy some that are properly suited for the weight of the vRS.

Job done.

At what point have I been arrogant?

Well I have got a HND and Degree in Automotive Engineering. I've spent the last 7 years working as a Design Engineer for several Tier One Automotive Companies and my weekend toy is a 600bhp Skyline engined 200sx which I built myself . . . so chances are your right.

Not really arogant, more of "In your face i am better than you" Which to be honest frustrates the hell out of me.

I have a degree too, as does a very large percentage of the people here on briskoda.

At the end of the day it doesnt matter. The srings are wrong. Its nearly as bad as buying springs for a 1960 series 2a landrover and making them fit onto a 1971 volkswagen beetle................... now theres an idea if i ever had one...... a 4x4 beetle

Anyway back on topic..... Ok you want to try, fair play to ya. Just dont ask the question again and feel all defensive when the answer isnt what you wanted to hear.

Now lets all be freinds and have done with it.

Btw to the OP, nice polo
