Hi guys !
I'd like to make a little point about the ring that apears on the tires.
I also had this problem on my first races with the type R. At this time I always used the JRLink (because I had never tried a regular link) with 2° of camber as I always did with my former cars.
Then I just tried to reduce the camber and it just made the car better, more front grip and more steering everywhere. That shows the tire works better like this (I mean flatter). I think tire wear is a good indication of how the suspension is working. You wouldn't even need a bench to set the camber, a look at your tire is enough. I usually set my camber between 0.5° and 1° both front and rear, it's strange but that's the way it works.
Now I almost always use a regular link on both carpet and asphalt tracks, it gives more steering at corner entry and at corner exit as well. With the regular link I still have those rings on the tires but it only apears after 4 or 5 runs. But tires don't all react the same. I mainly have this issue with sorex tires which are those we have to use in France
