Any issues with this setup? Am I going too low up front, especially compared to rear? The car has so much forward rake that I want to get rid of.

If you’re asking these questions, you likely already know the answers. 1M weight balance is slightly towards the front from BMW; dropping the front more than recommended will make the car handle worse, without dropping rear the same amount over recommended.
If you want to have front and rear wheel arches equally full with tire, i.e. equal fender gap, then you should set ohlins as recommended and run taller tire in front than in rear… which is what BMW has done with all M cars prior to 1M/e9x M3 (and the e92 M3 GTS).
