Track spring rates for KW Clubsports

Good evening guys, I wanted to get some of your input on if you think a 628F 784R spring is a good enough spread for the track. I see some guys running a 700/1000 on MCS's. I am on 2 way clubsports. It's mainly for 6-8 events per year, but still some street driving.

I currently have a 628F/672 installed (oem clubsport numbers), but have a set of 784's sitting in my garage that I am getting ready to install. Should I go stiffer (896 or 1008 are the next two options up) in the rear? I would rather not change the front spring again, but I could jump up to a 685 or a 742 up front.

Let me know your thoughts. Thank you in advance.

more than enough imo.... The valving is just as important.

TcKline will always run a softer spring and its works for them, my z4m on clubsports only comes with a 400Lb front spring and with the settings ramped up it feels like double that, again a very stiff chassis from the factory doesn't need silly spring rates.... imo of course.
