If I switch to oem sport would I use D4/D3?

Here are some threads about springs that I read up on.

I am swapping from Koni Yellow with Eibach Pro (installed last month) to ZSP springs, probably D6 Front and D4 Rear since I have a 6SP MT xDrive E90.
BTW, I will have D3 rear (from an 335is) coming my way which I am not using if you are interested.
