I don't understand it,I probably never will. I believe in the 'to each their own' but can't for the life of me figure out why these guys think putting 4 inches or less of ground clearance on their cars with no regard to safety is a good idea. Why take a perfectly good, balanced, well engineered sports car and lower it so far that you'd bottom out in a pot hole or on a speed bump, use rubber bands for tires that are just waiting to bust a bead on the next bump in the road. For f*** sake, you can't even drive it long distance because your #lowlife camber is going to give you the worst tire wear imaginable while you bounce and shake your way down the road with "illest" stickers over your turn signals and brake lights.
From what I am reading, there is no performance gain. The threads on the bookface and miata forums have the dumbest goddamn conversations about cutting springs and removing bump stops (sound familiar, 1990's Honda Civic?), using cheap coil-overs that were never meant for this purpose, and cracking their oil pans and ruining their CV joints and sub frames. These guys take perfectly good condition cars and destroy them. Hell, they even give advice to those who want a slammed car, never to buy a slammed car and instead, take a good condition vehicle and ruin it for yourself! http://forum.miata.net/vb/showthread.php?t=539555
Most of these folks don't know or care about the mechanics of the car, let alone the safety. They're only after an insanely low appearance with crappy paint, stickers everywhere, and wheels poking out an inch past the tire.
Godammit, go back to your Hondas and VW's- leave Miatas the f*** alone.
