ditto the daveB rings, definitely!
1) Driving school, definitely - absolute best first mod
2) daveB rings
3) cruise control
4) a real damn horn to replace the weak sheep's bleat
5) boost gauge
6) all that other stuff
Suspension: Fine as is, wait for the good kits to come out, esp the rear bar kit, it doesn't need to be any lower (doesn't have enough travel the wqay it is, and it's stiff enough).
A straight pipe to replace the rear muffler is a fun way to add sporty sound, of course does zip for performance. I like mine, tho - makes the hair on the back of my neck stand up when I blip the throttle in the parking garage at work...
