Hi guys I've been doing some work the last little while and will have plenty of free time and a small stockpile of cash, about 4k, to throw at my 2008 Impreza WRX. Atm I'm trying to plan out the basic mods I would like to do to my car. So far the only parts i know im definite on are sway bars after seeing the difference they made on my friends volvo S60 and that is also my complete experience with car modding. I will be trying to stick to DIY processes as much as possible because I want to A.) have the mods but B.) also be able to understand what i have done to my car and how it works.
I've been trolling the internet the last week and have made some vague progress in learning about tuning. IF i could be pointed in the direction of any resources that would be valuable learning tool, please link or if a book give title and author. Also feel free to list any mods you think i should investigate or research or if you want to explain them yourself feel free
