I'm not trying to be argumentative here, but something occurred to me today that I thought I'd suggest.
For those of you looking for the slammed look, who enjoy a very stiff ride, and who don't want to spend a lot of money I have something for you to ponder.
Take a stock suspension (GA16 car will do), throw out the springs, drill holes in the struts to drain them and allow them to compress fully. Put them back on the car and jack the car up to your desired height and then weld the struts solid.
I know that sounds completely f*сked up, but if you do it with an eye towards safety (maybe reinforce the piston some) it would be much cheaper, could go as low as you want without worrying about rubbing over bumps at all, and it would probably be safer too. I'm being completely serious with this suggestion and I'd do it to my own car (if I wanted the slammed look) before considering Megan Racing coilovers. At least as an experiment.
