I am going to go with MCS because there is great trackside support in the Pacific North West. My Z4M Roadster is a daily driver that may, over time, become a dedicated track car.
I am going with the MCS two way remote set-up because it - theoretically - offers higher performance and - mostly - because it is easier to adjust with the remotes being more accessible.
I have not pulled the trigger yet because COVID hit us fairly hard, but if things keep recovering the way they are (west coast of Canada) I hope to do the suspension upgrade in September.
