my Oettinger dealer said the same - V2 is the way to go, unless you do track
....V2 is suitable for track too. Though V3 is better for track because it has more adjustability, but you need to know what you are doing to achieve the best setup.
Tomorrow I'm going up to VW Racing to drive the suspension setup they've fitted on their demo car for me to try - It's tailor-made from KW and according to my brief for comfortable fast road use but with the capability of easy adjustment for occasional trackdays. They have chosen V2. As long as it's comfortable, they'll order the parts and fit a new set on my car.
