What do you want to do with the car? Daily drive? Track/autocross? Weekend canyon carving? There are a ton of builds on here for all different types of driving to get ideas. My car is also fairly new to me and I am well on my way to building what I want and have an idea of future parts I need. I want to build a fast daily driver so I went stage 1 with a drop in filter. I'll eventually go to stage 2 and get the FMIC, but handling and drivability is more important to me than power, so I got a set of nice sticky summer tires with more sidewall and a lighter set of wheels. I also got a stronger RMM, short shift adapter, and transmission bushings to make shifting more crisp and enjoyable. There is a ton of cool things you can do with this car, both for performance and for appearance. Just decide what you want, do your research, set a budget, and have fun! This forum is full of wonderful people with amazing amounts of car knowledge, so you won't have any trouble getting questions answered.
