The back end does squeek a little over speed humps
Hi,
if the rear is squeaking now, that may be the result of non-shortened PUR bump stops!
Post # 3 of this thread shows the instruction how to modify these yellow rubber bump stops in case of any lowering by sport springs.
Especially with Koni FSD plus lowering springs this PUR shortening is essential!
One thing I did notice was that it seems slightly lower at the back than the front.
The back is about 15mm lower, I will measure it tonight and get the exact difference.
As for the A2 rear getting lower than the front this mainly results from the implemented gas pressure of the front twin-tube FSD dampers along with a quite strong compression damping force setting of the FSD front shocks (that prevent the A2 front from bottoming).
To avoid this unsatisfying “back lower than front appearance”
the German A2 owners upgrading to Koni FSD or Bilstein B6 like to
modify their WEITEC / ABT / EIBACH etc front springs slightly before first installation.
This special procedure does
not apply cutting the springs (which would be irresponsible
) but instead uses defined homogeneous heat generated by electricity as well as defined compression to reduce the spring's free-length.
This modification does neither alter the spring steel properties nor does it weaken the spring durability!
Moreover the springs surface powder coating won't be harmed and the colour w/ labelling is maintained.
There's one German company specialised in this technique professionally. They customise almost any kind of car / bike springs for customers around the world (including professional racing sports).

For all A2s a
20 mm shorter front spring is highly recommended for proper looks in case of 20 to 35 mm lowering springs plus Koni FSD or Bilstein B6. The final result will be a true 30 to 40 mm lowering both at front and rear net.
Especially the light 1.4 petrol A2s will benefit from this front springs modification.
The latest example for that professional front springs mod is a German A2 1.4 TDI that has installed the gas high-pressurised (25 bars) Bilstein B8 shocks. He went to B8 because of lowering exceeding 35 mm...
Because this A2 has heavy stereo in the boot permanently, the A2 front had to be lowered even more to compensate for the additional rear weight. So the owner sent the 045VA ABT front springs to REUTER MOTORSPORT to get them professionally compressed by 20 mm each.
The result is an even 40 mm lowering at both axles despite the high pressure Bilstein gas shocks!
To summarise, for nice looks of your A2 I would like to highly recommend all future A2 owners intending to upgrade to
- WEITEC / FSD
- WEITEC / B6
- WEITEC / B8
- ABT / FSD
- ABT / B6
- ABT / B8
- etc

In case of a group buy, Mr. Reuter should give a discount for the front springs modification. Insured shipping to UK isn't that expensive (about 25 EUR).
