I thought i would post this since alot of people have been asking me how they worked out for me since i installed them. Im not a suspension expert or anything, but i am pretty good at driving, so ill try my best to explain. Had i went from stock shocks and springs to the Serialnines, anyone would obviously say that they are amazing coilovers and better than anything ever. Luckily i had the chance of trying out a previous set of coils before going to the Serialnine units. The Tein HA coilovers i had were decent, yet a bit too soft for my taste.
