I know it's been discussed many times...but I still didn't find enough answers for several hours...
1. Basic problem:
vibrations while braking with ufo ́s despite completely new VA suspensions (new cross-bar, new track rod heads, new steering dampers, ufos have also been replaced and since then already planned after which some time is quiet...starts always new)
solution idea: conversion af HP2
2. after my research in the ETKA there is min. 4 different HP2 systems...which would be:
of A8:
saddle: 4D0 615 107A and 108A for disc size 314x30
or
saddle 4D0 615 107B and 108B for disc size 323x30
or
from A4/S4:
saddle 8D0 615 107 and 108 for disc size 321x30
then there is still
from S6 plus (C4)
saddle 4A0 615 107A and 108A for the washers 323x30
There's probably more...
are there any differences between the variants regarding retrofittability on the original V8 fedrebein?
3. there are 2 bearing housings (spring) for the V8
first: 441 412 025 D and 026 D
and: 441 412 025 G and 026 G
now my fgnr.: 4CZ MN 003 503..so I would still have to have the all "D" version....is this version an unarmament possible? where are the underscvhiede zw. D and G?
hope to answer many who help me...
I am slowly despairing with the sch...UFO ́s....have it satiated!!!
