I've got the Megan Coils, going on over five years and 15K miles. not a single problem as a year round daily driver in Chicago... Needless to say the money was well spent. Only issue I had that related was that I had to replace the CV Boot due to being dropped too low... common problem, gotta pay to play.

 

meisters are chinese/taiwan made just like the other popular chinese coilovers. maybe u gotta try the newer tein basis z versions. i have them on my g37 and i love them. but if ur looking for something stiff and harsh then you wouldnt like them
