P11 Coilovers

I just purchased a P11, and I've read a lot about the suspension, but it seems everyone is using a custom spring and shock setup. I'm just looking for a coilover kit that I can use in conjunction with my stock shocks/struts, with the possibility of upgrading the shocks/struts in the future.. I tried to search for the info already, I can't seem to find much on the subject...Thanks in advance!
