I'm relatively new to sim racing (a few months) so if my performances were something my dog found on the ground, he'd think twice about rolling in it. I am reading the Skip Barber book and finding it educational, but I am suspecting that sim racing is not something you "get good at" in a couple of weeks (and it shouldn't be). I think a lot about driving and tuning and I've written some thoughtful TLDR posts that I thankfully never actually posted. But I still wonder and so I decided tonight would be a good night to ask a simple question and see what the good people here have to say. So, at what point should a novice driver concern himself with the setup of his car?
