If you plan to frequent the track with some road use thrown in as an extra then KW have released their clubsports with 3 way adjustment and the 2 way will be discontinued for the 1M. Great set up. I run KW DDC in my 1M and Clubsport on my trackday OPC. I removed a set of V3's after almost 6yrs and 35k miles and after a clean they looked as good as new, so cannot fault quality either!
