Title: TT-RS suspension fits GTI???
Post by: danishmkvgti on January 08, 2012, 08:18:07 pm
As mentioned i have just roughly measured some TT-RS dampers to my original GTI dampers and they appear to fit, any thoughts as to why they shouldn't :smiley:??

probably the only difference will be in the weighting of the springs etc!

Yes, dampers and springs will fit physically both FWD and AWD.
The main difference is the weight and Audi's setup.

Well then, i should be able to use the TT-RS dampers on the wife's Touran along with the Touran specific lowering springs i got?
Sounds like a plan  :happy2:

Yes, they will fit. Probably a nice setup on the stiffer side. Tell us about how it feels.

hmmm, not sure that will work well bud, a Touran (im guessing derv) will be a fair bit heavier than a TT!

This may make things easier.
And both aren't far away with both about 1.6 tons.

The TT-RS is quoted to be 1450kg and the Touran app. 1585kg. As the TT-RS has a harder it should firm the Touran up a bit.
I'm not sure if i should use the TT-RS springs or the FK Touran lowering springs i just bought???  :confused:
And yer it's a Touran derv  :wink:

No progressive springs - use linear springs only.

are any of the above springs linear Holger?  :smiley:

racing springs = linear

OEM = linear

Eibach = linear

most lowering springs = progressive

 :wink:

Actually Eibach springs are progressive. And you can get progressive racing springs, in fact it's used on the vast majority of race cars. That way you can get a softer car at slower speed corner with less downforce and a car that compresses less when hitting the harder part of the spring under high load/higher downforce levels. Bump rubber also play a big part too but you get the idea.

Anyway bringing this back to topic I would go with progressive aftermarket springs rather than OEM TTRS springs for your application. Near 150KG more compressing those springs can't be good. Get some springs that are made to cope with that load originally.

All Eibach springs for Mk.V and Mk.VI are linear. Eibach Pro are linear, Eibach Sportline
are linear and Volkswagen OE by Eibach are linear.
Don't get fooled when Eibach claims they are 'progressive' as they are not.

Ok, there are few car specific springs for mild racing purpose that are progressive.
Few. Very few.
All pure racing stuff is 60 mm and linear. If you think you need a progression you
have to mate two springs.

You're wrong mate.

From theory this is correct and that's why some racing teams use progessive rates
(provided by a pair of springs).


Anyway bringing this back to topic I would go with progressive aftermarket springs rather than OEM TTRS springs for your application. Near 150KG more compressing those springs can't be good. Get some springs that are made to cope with that load originally.

Using TT-RS springs seems somehow like an experiment, if Jake wants to take
this small risk - why don't he?

I'd avoid any progressive spring, because they handle worse than linear rated
springs. That's why Eibach don't sell them for the Golf and why Audi, BMW and
Volkswagen supply their cars with linear ones.

Incorrect, Eibach springs are progresive. Have a look on their website.

Every racing car I have driven since 2005 up to current has used progressive springs. It's really not that uncommon and the way things are moving progressive springs are used a great deal. Maybe not so much in road going track cars. You don't need to have two springs to get a progressive rate, this can be achieved in one. Again I know this as Eibach made custom progressive springs that I used.

I'm really not.  :happy2:

Not saying he shouldn't go with the TTRS spring, but I believe the TT handles better on Eibach springs. Every person I know that has gone to H&R or Eibach springs has also said so. 15+ people can't be wrong.

I'm just trying to give some insight and help out.  :smiley:

As i got the FK lowering springs at a very good price and already have them makes me tempted to use them.
BUT on the other hand they are made to accomodate the typical touran user, with a baret and pipe.
What i want is a GTI aftermarket spring feeling in the Touran, that's also why i plan to fit S3 alloy lower control arms front along with S3 alloy hubs. At the same time the GTI brakes will be fitted, (or maybe the R32 fronts i have spare  :laugh: ).
I wonder if the TT-RS springs will accomodate a more sporty ride than the FK lowering made for the Touran even though they are made for a car 150 Kg less???  :ashamed:

Ok, as we see you are not willing to learn. I don't understand such stupidity.
Otherwise you'd have read and understood this:


All Eibach springs for Mk.V and Mk.VI are linear. Eibach Pro are linear, Eibach Sportline
are linear and Volkswagen OE by Eibach are linear.
Don't get fooled when Eibach claims they are 'progressive' as they are not.


I had many Mk.5 Eibach springs in my own hands and I am able to recognize
if they are linear or progressive. It's obvious and easy to see.

But talking to pigheaded is pointless . . . .

Wasn't looking to get into a pointless bitchy arguments that doesn't solve anything. Only wanted to try and help out with regards to what springs work on the TTRS damper as is my side of knowledge. Didn't want this to happen  :fighting2:

Was told that the eibach springs have some progressive nature as listed on their website.

Don't get me wrong.  :wink:

It's just I often read wrong information on progressive vs. linear on forums.
This is caused by some misleading prosa on the manufacturer's website based
on marketing.
Marketing needs to sell products and so they claim what people like to read.
''Progressive'' sounds superior to most people, so they claim their springs so.

There's some misleading also as always, but quite informative though.
There's even more information in the Mk.V section as well.
