I think Ill just let the r40 for practice. Anyone nows where I can get it cheaper.
BTW thanks pacman25 I think you lead me to the light 
Rodrigo I drove my s710 today and I was very happy with the way it went, I set it up as per the manual then just dialed in some negative camber on the right side to compensate for tyre wear. I ran softer front tyres than normal with very little wear.
I will run the car tomorrow and will try some changes to roll centers to see what happens.
