Two things you need to know about Knockhill. If you can't see the top of the hill from the circuit it means it's raining. If you can see the top of the hill from the circuit it means it's about to rain.
If you are going Saturday you can park next to the circuit. On Sunday you'll get directed to the park and ride a couple of miles away. Getting in is ok but expect a bit of a delay getting out as several thousand people try to file onto a small fleet of double decker buses.
No real recomendations about where to stand, it's all pretty good, and it's not a long walk to go all around the circuit anyhow.
Did I mention the weather
