How are you liking your tanabes after all this time? Do you feel that the dampening is sufficient for a z31 with your spring rate? I've been doing quit a but of reading on other coilovers and now recently these new Stance coilovers. So far they seem to have a more positive reponse from people than the Megan Racing ones I was gong to buy. Of course without driving in a z31 with them I can't make a honest decision as to which is feel better.
