My father is in the market for a weekend toy/HPDE car. I've recommended an AP1 S2K given his needs/wants.
What are some good resources for him to read up on the car from a track toy's perspective? I don't want to point him to s2ki or H-T, but I'd like to give him something to read up on. He's an engineer, so he'd like to learn as much as possible before diving in.
If I have any specific questions, I'm sure you guys can answer them, but for general knowledge where should I send him?
