mine has apex -60mm suspension kit, 130,000 miles of running in, i change oil every 6k for decent stuff, gets hammered regularly, EBC GreenStuff brake pads, only engine performance mods are induction mods (airbox modified for maximum airflow and hks pannel filter) and mine flys for what it is!
get some 195/50/15 tyres on your standard 15" wheels too (or other 15" wheels you like, but stick to 15")
like yourself im only 17 and the car suits me perfectly, yep id love more power but it handles like no other car ive ever been in (been in loads of hot hatches that supposedly handle well
) its cheap to tax and insure, and im a lot less likely to kill myself in it
