It really depends on the springs that you get. Mine are a 2" drop and at least 1 strut is not blown after about 6000 miles. If you're gonna lower it, get both struts and springs like the other guy said.
As far as HID's go, if you're not sure about the reliability of whatever you're thinking about getting, Xenon Expert, an authorized vendor here, sells a DDM slimline kit for 130 with a lifetime warranty. Every single person that has it has said nothing but good things about it. I haven't seen a single complaint. Take it slow though and don't let the mod bug bite you too hard like me lately. I just spent a good 1200 on getting the lip painted, new grille, new intake, new exhaust, new........ so you can get a little carried away.
Make sure to also look at the For-Sale forums a lot. There are some AMAZING deals that pop up and you just gotta call dibs on stuff before the vultures get it lol. I almost forgot though. The struts you're gonna want are probably the Tokico HP blues since the illuminas (adjustable) are quite a bit pricier and a lot harder to find used.
I have an auto too so just realize that other than getting some naturally aspirated mods such as intake/header/exhaust and motor mounts and a few more little things, you really can't do much. Some have turbo'd their auto's but most of these guys are ppl that have other cars to rely on.
My advice is if you're wanting a couple of performance dealios (yes i said dealios), get an ebay intake such as this one
http://cgi.ebay.com/ebaymotors/MAZD...011QQitemZ320264375918QQrdZ1QQsspagenameZWDVW. I just bought it and it fits perfect. Also, since you don't really wanna sound ricey and annoying since the car is slow, get this exhaust. It's $110 and its a Mazda part so it fits perfect
http://www.msprotege.com/forum/showthread.php?t=123710907. Add a header like OBX and you're set. The muffler and intake should cost you about 160 for the two and make sure to buy a K&N filter for the intake to replace the bad one that comes with it.
There are also a bunch of easy, basically free mods that make the car look a lot better such as headlight blackout, side moldings shaving and a couple other. Just look on the How-To forum and you'll find a couple of them.
Good luck man and keep us updated!
