we need to delet the laptime here and add a Golf R japan spec... that different are to big..
I wouldn't go that far. What we have here is the fastest version - Euro spec. And what we keep here are fastest lap times. If they (BM) get a hold of Euro spec Golf or Scirocco or VW decides to raise boost on Japanese models, we would end up removing not just these laptimes but Jap spec carpages altogether.
Also, one variable in engine computer is not worth adding a new page. Multiple pages per one (or may it be similar) car degrade the user friendliness of this site.
This is a situation where we might end up having a poll for or against seperating Jap version.
