Depend on what type of racecars, F1 needs lotta grip but not too much (make it if you push it too hard its gonna spin out) Touring car tends to be stable and good at handling so maybe less grip but don't make it to the point where its gonna drift (make it understeer when you not pushing hard enough and spin out if too much) Gokarts tend to be very sensitive to movement though can still spins out
