No probs mate, I know it's a bit basic. To be honest with you Andrew, the best way to see what different pistons, springs and oil does to the handling is to play around with them yourself. You alone know how you would like your car to feel, everyone has different likes/dislikes. I have 2 sets of shocks, I set each pair up differently and try them out on the track. Your not long in seeing whats what.
