Hey All,
Just a heads up to let you all know that some of the fake Tein springs are now being sold here in Australia.
A friend of mine bought a set for his WRX and when he went to get them fitted the mechanic noticed that the springs were a bit different - further 'investigations' by him and my buddy comparing the box with mine proved that the springs were fake.
Tein USA put this up a long time ago but this should give you some idea:

Further to the above differences, I also noticed that the insdie packing was different .
