Hey bud, i'm glad these are working right for you! Maybe Megan's have gotten better since the last time I've tried them (They were PITA to DD), good thing to hear they are OK!12 and 10 doesnt feel harsh at all, the roads where i live are rough too. I did spend some time playing with the dampers to get it feeling right. When i used hit bumps with the tein super streets it would all be a big bang and shake through the car but now its alot less harsh with the megans. End of the day im really happy with these coil overs and i would recommend them to any one doing weekend tracks and looking into the cheaper coil over market, seriusly a grand delivered its cheap and they work better than a 2 grand set. Ill let everyone know how the go in the long term but from the american forums guys have been using them for years with out issues and regular track days
