What size spacer with TCK D/A and Kosei K1

[momoboy]

I am purchasing a set of Kosei K1's for my E36 M3. I haven't finalized my tire selection yet but the size I am going with will be 245/40/17 all around. I have a TCK D/A coilover suspension and will be using Kosei K1's. What size spacer do you recommend and is there a "best" brand?

If you run 235/40 you won't rub. Also, I hear 10-12mm spacers are needed in front to run bigger than 235.

I run a 5mm spacer with k1's and 245/45 v710's and it is needed to run that setup regardless of tire size. Any tire wide enough on those wheels will require a minimal spacer.
