*Lose the cannon *16" wheels are the upper limits to what I'd run, 15" are even better *Extractors do make a fair bit of difference, Hurricane or Tiger headers are pretty cheap and work a lot better than the Pacemakers. *If you're paying more than $400 for a catback system, you're getting ripped off *2" catback is all I would run, any bigger and it's going to sound terrible. *CAI is pretty easy to do, all you need is a 3" 45* and a 3" 90* plus a small vacuum fitting. All you're required to do is cut them to length and weld it up, or even just join them with a silicone joiner. *King springs aren't great if you still want your car to handle decent. Don't forget that most EP92 Starlet stuff will bolt onto your car - I'd found a set of low km TRD adjustables for $500, they would handle MUCH better than just Kings. *Finally, make sure you get a Superpro bush kit and have them installed. It will make a HUGE difference.
