Well from where your spring platform is set I doubt its too low, although it could be. Possibly your wheels are just too big or the offset is too high. Theres a lot of things it could be. If you could put on here your original wheel width, diameter and offset, along with what size tyre you had, then also the same info for your new wheels then itll be pretty obvious what the problem is.
If youre still running the same wheels as before you had the coilovers put on, then it can only be the coilovers are set too low, or if you want to run that ride height you need harder springs. Or you need to not turn corners LOL
