I’m considering of fitting on my car TT alloy arms, ball joints and alloy swivels bearing.
But all information about those modification are a bit confuse and scattered, so below you’ll find an overview of what I understood reading several tread:

TT arms are about 6mm longer than GTI/A3 ones and TT ball joint have oblong shape holes which provide 6mm more to play around.
TT arms are also 1,8kg each lighter than GTI/A3 ones.
All together TT arm and ball joint give at the minimum set up 1,6° negative camber and at the maximum set up 2,4° of negative camber.
Parts numbers are:
1- Lower control arm:
Amount required=2 total, 1 per side
Part number=8J0 407 151 D
2- Bolt to attach lower arm :
Amount required= 2 total, 1 per side
Part Number=N 101 410 03
3- Ball Joints:
Amount required= 2 total, 1 per side
Part number= 8J0 407 365 (LEFT SIDE), 8J0 407 366 (RIGHT SIDE)
4- Ball Joint bolts:
Amount required= 6 total, (3 per side)
Part Number= N103 320 02
5- Ball Joint Lock Plates:
Amount required= 2 total, 1 each side
Part number= 8J0 407 175 (176)
But about the swivels, I don’t know if I go for TT ones or S3 ones.
I would like to use TT ones as they provide higher rolling center and Audi A3 race car use them for Nürburgring 24H race.
But, if they seem to look very similar, according to Service Training Audi TT file, TT swivel bearing widen the track of about 13mm each side.
And specific TT track rod outer joint have to used too.
Parts numbers are:
S3 parts number : 3C0 407 253 F replace 257 F
3C0 407 254 F Replace 258 F
TT parts number : 8J0 407 253 D
8J0 407 254 D
Can anyone confirm that TT swivel widen the track or not?
Because it seems that TT arms already widen the track from about 6 to 12mm.
Every comment or further information are welcome.
