Cheap coilovers will give you a horrible ride and break down (need revalving). A properly matched strut and spring combo is much better than a cheap coilover setup. Honestly, you only need coilovers if you need extreme adjustability/track use.
What is the use? DD? AutoX? What is your budget?
Personally, I am not a fan of H&R there are much better options out there.
If you are gonna match them with the stock struts:
Mach V Blues
If with an upgraded strut (i.e. Koni Insterts, Tokico Dspecs):
RCE Blacks or Yellows
