SC10 4x4

[ASKay]

hi all, new to SC and wondered what on earth people run for these things (specifically a SC10 4x4) on Astro, I was looking at the destruction manual, so I am now understanding the options.... So are the stock springs any use or do i need to bin these and get some option ones?... I am guessing the tyres are of no use on Astro, was looking at the Fastrax tyres are these the best choice if so, bullseye or kingcourse? I assume you stick to one type all around and don't mix them up (fronts and rears)?

I have Team Orion 6000Mah 90C sticks, I should imagen these will be ok, but was thinking about starting out with my Speed passion LPF speedo, using a SP V3.0 7.5 I know its a lightweight in terms of a speedo, (is this a no...no...?)....

Also really like the Proline Flowtek body, I heard that the stock body is a little weak, is this the case?

Also any other general tips, advice that are helpful, would be good.

thanks
