Cougar, astro uppgrades?

[Nedro]

Hello!

Been looking around for a while and trying to decide what option parts i should buy for my cougar SV.

Would grade myself as a newbie, started driving and racing this early spring.

By now i have gotten a pretty good hand with the car and have running it as kit.

I been looking into the +8 mm chassie and maybe some weightkits.
But after looking at the setups that people use on astro it seems that your driving with short wheelbase?

So even with all the praise it have gotten it seems it's just for dirt/clay?

So all and all what hot ups do you guys think i should get?

As i think now it's, Spring kits, a little more oils. Some weights and maybe chassie or new alugearbox?

Also now im running a 6,5t motor and are going to change it to a 8,5t probly to calm the car down also for a beginner like me. what Spurgear and pion is recommended?

Well sorry about the long and complicated post.
And last a fish eye pic over the course so you get an idea of how big jumps and stuff are:
