2008 Corolla LE performance upgrades?

Im already looking at cosmetic upgrades but Im having a hard time finding any performance upgrades:( Does anyone have any suggestions on where I can go on the web or in person around Northern Illinois to find any upgrades? Preferably bolt on but even places that did custom work would help. Ive hit a wall so to speak lol Appreciate any input you have:) I work on cars so installing myself wouldnt be a problem. Just need the damn parts lol FB_IMG_1558075038965.jpg
