Mostly stock (performance-wise). Current aesthetic mods so far:
Exterior:
1. Hella E-codes w/H4s - the stock sealed beams are useless. I did this mod within 10 minutes of getting the car.
2. Euro-style DRL bumper lights - turn signals relocated to the inner portion with DRL lamps at the corners.
3. Hella fog lights - really brightens up the area in front of the car.
4. Half-nose mask to avoid those nasty chips. IMO, it looks great as a contrasting element on a white car such as mine.
5. NC Miata style clear lights with black shrouds - no el-cheapo chrome or white shrouds over here.
6. LED turn signal, reverse, brake, third brake and license plate lights at the back.
7. OEM soft top - replaced the dingy aftermarket soft top with a better quality one. Not sure if this is classified as a "mod" though. :D
Interior:
1. DIY chrome dress-up - Painted the a/c and defroster vents, HVAC console panel and door cups in chrome. Not the super high gloss variety but more of a subdued matte tone.
2. Sony GTX music system
3. Sony 5 1/4" door speakers
4. Clearwater 3.5" headrest speakers with re-wired connections for better sound.
5. DIY mirror lights - a better alternative to throwing out those visors.

Planned mods (to be installed before the end of summer):
1. Proper strut bar - FlyinMiata or other name brands.
2. 15" Konig Heliums (black w/polished lip) mounted on Falken Azenis/Toyos.
3. Borla/FM catback exhaust
4. FM turbo kit
5. Fidanza flywheel
6. ACT heavy duty clutch
7. Hard dog dual hoop roll bar

Leave a message if you think I need to chuck something out and/or put another mod in there. Thanks for looking!

P.S.: The pictures are a bit outdated. I'll update 'em shortly.
