SupaStox Spares

[morpheus2010]

Making up my wish list for a Shoomy SupaStox to GT12.1 spec before ordering

Hoping to get some advice on the spares/pit box extras for the inevitable breakages.

What are the commonest bits that tend to be broken so I can repair and carry on.

Also getting 70T 48dp Diff/axle, what is a good starter pinion to match with a 13.5 brushless (Dynamite Platinum) on Twisty short circuit

Any advice would be appreciated
