I woulid not estimate those number.
more like 5.0-5.1 to 60
and 13.4-13.5 in the 1/4
The S54 M coupe runs ~ 4.8-5.0 seconds to 60 and 13.4-13.3 in the 1/4mi
The Z4 3.0i is only about 100lbs lighter than the S54 M Coupe.
No way it will do 12.5 in the 1/4mi.
If you say the S54 M coupe is heavier, even by 100 lb. why did you estimate the Z4 to run slower? Also, according to carpoint, the Z4 3.0L weighs 2998 lb and the M3 Coupe weighs 3415 lb. That's 417lb, not 100lb.
