Hi everyone my son just got a 08 wrx and wants to start doing trackdays. It has 19000 miles on it and is all stock. What kind of things should we do and or change before we head out. Also he plans on graudully up grade stuff. We have some qustions about wheel sizes and offsets that he should look into, but taken into mind if it is best to lower it ? what suspension setup is best for track use ie shocks ,springs ,sway bars, cross braces,a arms, all tht stuff . So looking for help and info that can educate us on this stuff.
