To be honest, since you're planning on spending the next 4+ years going to college, I'd look seriously at ALL of the mechanicals on your car first. Then I'd look at a rim and tire change (maybe, due to thefts in the parking lot). But still, I'd probably keep it all 100% stock, and drive it and maintain it. At 135K, you should be able to put on another 100K without having to spend a lot of money. This savings could be put toward tools, a hydraulic floor jack, jack stands, tune up parts and or an emergency fund for an unexpected needed now repair. Just a thought.
