What is the difference between un-revised and revised Z springs? Does the year of the Z spring matter?? What i want to do with the car is
1. Lower the car an inch.. are tein springs the way to go?
2. needs suggestions on compents for better handling
for example front and rear strut bars etc.
I intend to get the intake spacer in the future..
3. do I need aftermarket sway bars?

Part II

2. No sat button on dash? can i get satellite radio through the dealer ?
