Dex210 what parts to take racing?

[StuartH]

Hi, my son and I both have the dex210 rtr buggies and have started racing down at Eden park raceway in the south. We have already broken a few parts and replaced them and have spares to cover those expected breakages.

We tend to turn up with our cars as is and just drive hopefully getting better as the day goes on. Both cars are now mid motor and have schumacher minispikes all round. As we now crash a bit less I need ideas as to what to get to start to tune the cars at the track.

Aside from tyres I have little idea of what extras I should get for the toolbox that would make an impact. Ideas please!
