XRAY - Model racing cars

Hey,

I am interested in some general thoughts what you think is useful to change for a very large track with llarge and wide curves and many full speed sections?
What are the things that you would try and which effects would you suspect?

My first thougts would be a one way and low diff position to get better through fast curves. What are your thoughts?
Thanks in advance

Tighten your belts
Depends on the track but when the grip comes up really tighten the rear diff
Depends on what you run but consider a different bodyshell more suited to that type of track
Lower your ride height if the surface allows.
Depends on your setup but reducing your toe can be advantageous

If the track allows I would then play with stiffening up the car; chassis and shocks/oil - although I have to admit that I have not had a great deal of success with fitting stiffer springs, might just be me but I can never seem to get the balance right when I do

HTH

Ok thanks for your reply.
What are your thoughts about shock position? More inclined or declined?
Would you change the rollcenter?
