You can't go wrong with kw, great ride,good mix of comfort and hardness and solid as a rock reliability. Had the variant 1's on my mk4 golf for 6 years, dropped right on the floor, plenty of spirited driving including a bit of pothole abuse and the tree incident that ended the poor old golf's life.. Buckled an alloy but all 4 coilovers came off unscathed, cleaned up to look almost as new and have now been fitted to a mates bora and running well...
They are pricey but ask anyone in the know - they're worth it......
