TT Mk2 Lower Control Arms & Ball Joints
This is a great modification. I repeat the part numbers below so it is clear what I did.
I purchased these in Germany, and got them forwarded by a German freight forwarder. Part price around AU $540. Shipping around AU $80.
TT Mk2 arms are exactly the same length as the GTI ones and TT Mk2 ball joints have oblong shape holes which provide 6mm adjustment 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.
Previously I had a WALK and WL bushings, but after only 15,000 km they are pretty much shot. Anyone want to buy them? :bonk: Guess I shouldn't have said they were shot.
Ben from
Pedders South Melbourne looked at the options, and we agreed that using the complete TT Mk2 system was the best way to do the mounting.
The TT Mk2 mounts have one mounting hole (from three) slightly offset from the GTI / Jetta. Solution is to slot the end hole, and it fits. Pictures demonstrate.
