I haven't had money to do anything really yet. DIY mesh grille, de-badged, black out headlights when it warms up and I have a couple days to take the bumper and car apart. When I get the money, first up this summer are bigger sway bars (25mm rear, 20-22 front), springs/struts and new wheels and tires (I've curbed my stockers one too many times this winter having fun in the snow). I've got a 100k mile warranty and only 37k miles so I can't do much in the engine. As money comes in, cobb AP, CBE, high flow DP, short ram intake.
