I'm curious to know if roadster owners got the 8k,10k spring rates or higher for a daily car with few track days in summer.

i don't track my car. but i do prefer a stiff/firm ride, and i was planning on lowering my car quite a bit, so i wanted something stiffer that would have less of a chance of bottoming out.
8k in the front and 10k in the rear is what is recommended for the e85/e86 z4m platform. it's all about what YOU want. 8k and 10k will probably give you a very close to z4m stock suspension feel. however, i went 2k more for front and back, and i still feel like it's a very comfortable ride. i'm very happy with the way it all turned out.
