Probably the most sound way to liven up an M car is to look at the differences between the base car and the top GTS/CSL cars. Namely transmission and engine software, suspension kits (GTS often has KW clubsports), and factory lightening/NVH padding removal. With the G82, you could even take a look at the M4 GT4 and see what the differences are.
Make the summers run flats to stiffen them up more. Might get a teeth rattler like the original straight sport suspension package combined with RFT were.

Remember taking brand new RF summers tires off my 2011 335is 7DCT because they would rattle your teeth on some city streets
