MK5 and 6 Tie-Rod Extenders in M16 thread size and 1.5 pitch.
These are needed once negative camber surpasses 3-5 degrees depending on how that camber is achieved.
Lifted vehicles also use these and are very popular with Tiguan owners.
Modification to the tie-rod may be needed, if you only need a few more threads, you will need to trim the tie rod down by a 1/2-3/4" so that the range of threads available is suitable. If not the extender may extend too much.
Sold in pairs. (2)
