For springs i would say Tein or H&R good quality and reasonable pricing for coils i would have say Tein or Tanabe again quality and pricing haven't had much experience with the other brands.
I will add BC Racing also because you can order a set with custom rate springs at no additional charge so its becoming a popular buy on the forum.
I'm currently running a set of KW V3's on another build and they honestly ride fantastic. They're at a much higher cost point than most, but they ride so smooth on the street if adjusted properly. They ride smoother than our 2010 GX460, and that's kinda a women's car....just saying.
