Mods for street-driving, stock look owners

[SeattleLion]

Since a lot of people here are into mods for appearance or performance, it can get confusing for someone who wants to make changes that will make the Z a better, safer street car.

So far I added:

• An invisible bra on the front bumper, lights, partway up the hood, the mirrors, and the door edges.
• Changed brake lines to SS (Goodridge) and changed fluid to AP Racing DOT 5.1.
• Added a backup cam
• Changed the summer tires (Bridgstone Potenza) that came with the car, to Michelin Piolot Sport A/S Plus. (all weather and Z rating)
• Bought a new radar dectector (Escort 9500ix -- it has GPS and a database of red light cameras and speed traps) and had it wired. It is in a bracket that puts the detector under the rearview mirror.

The car is a 2010 touring with sport package and navi.

What have others done for a strictly street, none show car?

This might make a good sticky thread. I had to wade through a hundred threads to get to what I finally did.
