Excellent cheers for that.
The CRP rear shock mountings are a must, as you mentioned about the self tappers ruining the plastic I have one screw mounting that the hole has bored out the standard shock mounting black plastic and was going to temporarly put a bolt in.
Also the way yours is braced to the front shock tower seems a good mod it does seem to twist and they always did.
I am fitting a 27turn motor at the moment as I have a spare 27t limit ESC and as my daughter will be using it as well it will still be to fast for her.
Watch this space, all being well I'll be starting this at the weekend once the bearings turn up. Just need to decide on what to do with the body as its not in the best of conditions but could be repaired.
