So as everyone knows i have Racing Logic "Ultra Complex" coilovers... the front two are leaking oil. Spring rates are 8kg front, and 6kg rear. a few has suggested reaching out to k-sport for replacement cartridges, but honestly i am not sure where to even begin looking. i've sent a few emails to RL and nothing back yet. the coilovers retail for ~1700 new so ... yeah im not buying new ones.
