it would interest me to find out why the tuner i have spoke to suggested the KWv3's "since the car is equipped with with DSG"!
....Which tuner is saying this? It sounds suspiciously as if he's got stock of KW-V3's he wants to sell. DSG has absolutely no influence on the choice of suspension.
as you guys have noted, the v2's are good enough if your not really going out to be doing track days 24/7.
i do remember someone talking about back end bounce?
maybe its something to do with that.
....V2's, V1's, V3's, KoniFSD's, etc, are all good enough for either road or track or both. As I've said, it's just a matter of which suits your preferred personal balance of handling and comfort. Oh, and I'm forgetting that some people do it just for looks, so I should add cosmetics. I disagree that not doing track days 24/7 means that V3's are a waste - Some of the roads I drive on (whenever I can) are just as testing as a track and far more interesting. In fact, the suspension is sometimes given more of a workout because the road surface is not as smooth as a track.
You've got to be really pushing to get "back end bounce" and the stock GTI has a degree (3 degrees IIRC) of rear end camber adjustment. << EDIT:- I've just realised you probably mean continual vertical back end bounce from having suspension wrongly set up. I thought you meant horizontal bounce or skip.
What will make a difference to lap times on track is having the ability to set up more camber and that adjustability can be added with top mounts. The trade-off then is uneven tyre wear if also used for extensive motorway driving.
This is why I went to VWR - They fitted me a Fast Road suspension which is practical and perfectly set up. I'm not capable of setting up my own suspension to the optimum.
