XRAY - Model racing cars

Hello everybody. This is something that I was spend a lot of time thinking about that.

How can I get fast steering response (but not initial response, I reffer "total" response).

For example in the front shocks If I put less rebound, the front of the car has great agility, it is correct?

About piston, If I use piston with a bigger holes? has the same consequences?

More rebound will make the car feel more direct initially, but will have less overall traction. Bigger holes will give a similar effect to using lighter shock oil. This will make the car feel more direct too.
