Hi There,
They're an excellent car out of the box. They handle well, are very strong, and there is plenty of support for setups and advice.
It comes with a roll bars all round, but there is a set of heavier ones that are useful to further tune it to the track. Kit bars are fine to start though.
A lot of people use the 8 or 11 degree alloy caster blocks, but this is personal preference and some prefer the standard 5 degree versions in the box. I'd recommend building it standard to start with and go from there.
As with any car, there are always options to tune it to the track or driving style, but i wouldn't rate any as essential.
