Set up help

[shep]

Hello everyone, I am very new to the rc scence and have got myself a second hand durango dex410 v3. I run on high grip astor, At the moment i don't have the anti tool bars installed. What difference do they really make?

Also there are ALOT of difference mounting holes on the shock towers, do these make much difference? If so what position has what effect?

Last this is my current set up is it about right for a tight high astro track?
10k oil in the front diff
7k oil in the rear diff
42.5w oil in the front shocks
25w oil in the rear shock.

I know this is a big ask and it is probably a lot about the driver and how he likes to drive but any help would be great.
Thanks
Harry
