[BiturboS4] KW coilovers

[David]

Hello,
I want to improve the handling of my S4, witch I use sometimes on track.
I've found a complete second hand KW coilover Variant 2 Kit (one year and
10000 Kms of use) at a very good price. But I don't have any reference of
this German brand.
Is there anyone who has them ? Any experiences regarding this brand ?
