Ground Control help:
I am hearing some bad things about Ground Control stuff and need some info from people who know:
1)the parts that hold the coilover onto the strut are rubber and plastic, which break down and detereiote over time.
2)The set screw for adjustments rusts out really fast and gets stuck.
3)they design the coilovers based on the fact that you are going to lower your car. So If you don't lower it, and the srping is a little funky and it rides like crap.

Any truth to these things i have been hearing? Anyone used ground control stuff for a long time on a car? How did they hold up.
Thanks in advance!
