A well sprung and damped car can yield a quality street ride and still rock on the track and will be my ultimate goal.

M2/M2C uses stiffer springs than the M3/4 (including ZCP variants). The rear spring is progressive though, which might by why you think it feels softer.
For the amount of money a good coilover set will cost you, I would go with a Fat Cat Motorsports bespoke tuned suspension. They use Bilstein donor units and custom valve them (as well as having some proprietary tricks of their own to add to them) to get a smooth/quality ride on the street while still being able to control and grip very well on the track. He can recommend spring rates to use for the ride frequencies you want.
