Koni FSD + Weitec = ?

1.2 Springs and dampers

Thanks Schnelletrecker

I will look into this and ask Koni and Bilstein.

Do you know any details of what the standard springs and shocks are? Audi dealer shows about 8 different A2 springs (all colour coded).

Erling - Will bear you in mind also!
 
Regarding different spring rates for the 1.2 TDI:

For all 1.2 there should only exist one type of rear springs– meaning identical load rating at the rear.

Because there are 1.2 TDIs coming with or without air-con, there will be a minimum of 2 different front spring rates available. Different spring loads are expressed by those varying colour codes (sorry I don't know these 1.2 specific colour codes and their corresponding spring rates :( ).

Just replace all four too softly tuned 1.2 stock dampers (made by Sachs I believe) by custom made shocks and combine them with your existing springs.

Regards
 
FSD upgrade worth the effort - Thanks!

Just wanted to say thanks to all those contributors in the forum who recommended Koni FSD shocks for extra comfort. Having had them fitted a couple of hundred miles ago (at long last got around to getting them put in even tho I bought them last November!) - I consider it to have been well worth it. The ride is considerably gentler and - I would argue - safer, as the higher quality shocks deliver better all round tyre to road contact.

There's no way I intend hitting speed ramps faster. I am just glad that the rather severe judders and the sounds of my wiper bouncing off the windscreen whenever I hit a bad pothole [of which there are many on Irish roads!] are now hugely reduced. It makes the A2 driving experience all the more pleasant.

Thanks for sharing the collective wisdom.

Hi Damo,

It is good to read that the Konis have worked well for you too. I think everyone on here who has fitted the Koni FSD shocks has not regretted the change. They are expensive, but if you plan to hold onto your car for a while, then I suggest that they are worth it.

cutting the bump stops is essential!

:)

I would like to remind, that in case of any lowering with sport springs (not coilovers) the yellow PUR bump stop rubbers have to be shortened!

So in case of WEITEC 30/30 for instance please cut each of these PUR-rubber 30 mm down using a sharp carpet cutter.

The rear rubbers however – each holding the black damper dust cap – must do without a 30 mm intermediate piece (see pic below). So please glue both remaining pieces (preferably at same outer diameter) together again with superglue.

This shortening of the bump stops is essential to make sufficient suspension travel available in combination with lowering springs. That is very important for the Koni FSD (frequency selective damping) technology as well (when it has to deal with sport springs) because restricted suspension travel will result in altered body motion frequencies.

Please do not shorten these yellow bump stop rubbers beyound 40 mm since the bottom valve of the dampers can be damaged potentially if using standard length dampers such like Koni yellow sport (non shortened), Koni FSD or Bilstein B6.
 
I suspect this may not have been done when Awesome fitted my FSD's and Weitecs.......Has anyone done this and is it as beneficial as suggested?
 
Since this shortening procedure is standard (= a must) for any lowering by sport springs (if using the regular stock bump stops), Awesome most probably will have done this bump stop adoption.

If not, they have to touch up for free. :eek:

The amount of hard-foam shortening generally equals to the amount of lowering by sport springs...
