Best brand for performance parts?

[Fromdabrazyy]

Hey guys just got a Mazdaspeed 3 2010 a few months ago, been playing around with it now I'm ready to start modding it, any suggestions on which road to take? Cobb and corksport each have their own stages of tuning. What do you guys think I should go with? Thanks:)

Fuel pump/fuel pump internals and Cobb Accessport should be first on the list and then go from there
