That's an interresting conclusion of a valid trial and error process.
The question is : does it also apply to the 1.4 Petrol ?
(with 30/0 instead of 35/0 maybe ?)

Yes,
In case of Weitec 30/00 the 1.4 petrol owners should have compressed the front Weitec springs by 20 mm each for acceptable looks.
More recommendations to optimise the A2 appearance as a Koni FSD user:

BTW, Weitec 30/00 and Weitec 35/00 do represent exactly the same front springs! - There's no difference at all...

Now I'm confused...
If Weitec front springs are compressed 20mm more, that's means they are -30mm -20mm = -50mm compared to orginals. And with standard springs at the rear (because 30/00), I guess the look would be rather strange ??

no, because they don't really give -30, more like -15 - 20. The -20 then sort of assures a mild drop at the front in comparison to the rear; if you drive around with a sub and amp in the boot, then that's another 10mm down already... so you've only got a 15-20 difference.

calc:
- 15 mm of lowering net of the Weitec front springs (stock non-modified)
- 20 mm of lowering net due to the professional spring modification (by Reuter Motorsport)
+ 10 mm of lift induced by the front Koni FSD shocks
---------------------------------------------------------------------------
= - 25 mm of lowering net
Koni FSD shocks can be applied up to a maximum lowering rate of 35 mm net.

I know this is now probably the wrong thread to post this in, but I got my FSD/Weitec kit installed today. For the record, I have gone with the Weitec 30/00 setup which seems to be the way to go. I shortened my front bumpstops by 20mm, and at the same time replaced front strut mounts and also rear bump stops. I then for a full 4wheel alignment done (which was interesting!).
The difference is incredibly striking. I honestly didn't expect it to be such a transformation, but that's pretty much what it is. The car rides smoothly instead of crashing and jarring. The car sounds quieter too over bumps. It also turns into bends more positively. But the ride is still firm, and it doesn't float. So it's not that it's gone all soft and French on you, but it's just better. Vastly better. It now feels like a proper solid grown up car. These FSD shocks must be very good indeed. Do any cars have these on them out of the factory?
At some point I would like to swap out the OE Audi springs with some replacments, just to complete the job really, but until Weitec make a -10mm lowering spring for the rears only, I'll stick with what I've got.
The 4 wheel alignment showed up some rather eye-wateringly bad mis-alignments -my front right was -1degree out on camber! Everything is now decently aligned within spec, so hopefully the car should pull and stop in a straight line, and hopefully tyre wear should be relatively even.
This weekend I'll be doing a 300mile round trip mostly on motorways so I look forward to running the shocks in and seeing continued improvements!

The FSD dampers do require about 2000 miles to break-in fully and thus to become smoother. So do the Bilstein B6 or B8 shocks.
There's no need to swap your rear Audi springs - so far there's only one case known of a broken rear Audi stock spring (Spike).

Then fit the Sport springs rather than the standard SE springs Dan. From what I have been told, the Sport springs are ~10mm lower than SE or standard. This should make the car look better. I intend to either swap my rear Weitecs for Sports or better still get some -40mm front springs or get the front Weitecs compressed by 10 or 15mm. Are there any -40mm springs available for the A2 that could be fitted to the front? Not sure I want the hassle of sending a pair of springs all the way to Germany and back to have them compressed though. Is there anyone in the UK that does this work?I would only like to swap the rear springs in order to achive the ~10mm lowering at the back that I've got at the front just for purity of aesthetics you understand
Cheers,

What did i say Dan these are a great bit of kit and well worth the money just getting all the other bits together then ordering shocks

Well, we must not put minus (true) 40 mm springs from one spring maker and combine these with different make rear springs (e.g. front ABT + rear Weitec).
That mixing is only allowed with Weitec front springs and the Audi rear springs (the Weitec 30/00 kit is fully TÜV approved!).
So the only alternative would be compressing the front springs professionally - be it front sport springs made by
- Weitec (30/00 or 30/00 kit)
- ABT (35/35)
- Eibach (30/30)
- KAW (50/30 - these are only 30/30 net actually)
- FK (35/35)
- KW (30/30)
- etc.

So is that true then - could I fit OE Audi A2 Sport rear springs to achieve a 10mm lowering at the back over my SE suspension to match the lowering I've achieved at the frong with the Weitec 30+FSD uplift net lowering of 10-15mm, thereby giving the car an overall lowering without resorting to the sh*tting dog appearance?
Schnelletrecker

Sure you could fit the original Audi sport rear springs since these do represent Audi OEM springs still matching the WEITEC 30/00 TÜV-certificate. But the risk of a possible "sh*tting dog appearance" will increase then...
@dan_b
Would you please measure the vertical distance between the wheel center and the wheel arch at each corner of your 1.4 TDI?

"In all above listed cases the A2 rear is prone to sit lower than the front if combined with Koni FSD shocks."
This is NOT the case. With my Weitec 30/00 combo, the rear of the car sits 21mm HIGHER than the front.
It takes a confident or foolhardy soul to argue with Schnelletrecker on suspension issues!
I am really enjoying this thread - by the time I can afford to get Ada's FSD's I will have an exact spec list of everything to buy and how to fit them! Go A2OC!

So if you bargain for another 10mm off if you fit the Audi OEM Sport springs at the rear, retaining the TUV, then you should be near enough level. Sorted!!

Where are you measuring? I have just measured down straight down the wheel to the centre bottom edge of the wheel arch from the ground and got 64cms front & back.
The seller mentioned that my A2 had sports suspension when I bought it; I would be grateful if anyone with a standard TDI SE and 17" wheels could measure their height from ground to wheel arch, so I can compare. Thanks!
Schnelletrecker

Sorry, but measuring from the ground to the centre bottom edge of the wheel arch isn't objective!
Every tyre make (with same dimensions such like 205/40R17) does have a different circumference. Some tyres are worn, some are new with full 8 mm of thread depth.
Or just take the deviation between 155/65R15 ( = standard winter tyre for the A2) and the 205/40R17 tyre of the sport: With these 155s winter tyres fitted the A2 does sit noticeably lower than with the 205s.
So the only objective way to compare the car height (on horizontal ground) is measuring the distance between the centre bottom edge of the wheel arch and the wheel centre!
Stock OEM A2 SE suspension typically ranges between 35 and 36 cm of distance.
The original Audi sports supension springs mainly lead to a distance of 34 to 35 cm - often there's no 10 mm drop recognisable though with the Audi sport suspension fitted...
A full tank can make the rear drop about 5 mm...
