I'll start with mine, first winter with new tires.  
Mods: 
Weapon-R cold air intake 
After market chrome on pillars and mirrors 
Resonator delete 
Mud flaps (not necessary, but look awesome!) 
Four new pioneer speakers + 10" sub  
Hopefully in the near future; 
Replacing mufflers with glasspacks, and new tips. Plus I plan to detail the car with plastidip. It's only in plans now. If anyone wants to see the Photoshop rendering let me know.  
  
Please, I would love to see everyone else's edge! I love to see how people design their vehicle.
