Trying to, i've got brand new q3s and no leaks. May need to change pads.

Someone was telling me i had to drain and swap coolant with a race approved coolant and some other jazz that i didnt understand that involved the oil cap,drain plug and filter....any idea what they were talking about?

Also wondering what the costs are to run plus rent a race suit etc. Think all my helmets exceed the 5 year limit as well.
