Yes u r right . The Z4 M Coupe is the better balanced an handling car in stock form. But the old Z3 version (I had a 2002 model with the S54 engine) is more exciting and scary in some way. The rear end will try to overtake the front in almost any sharp driven corner. This car was a beast, crazy driving dynamics but very rewarding once u learn to tame it. It made me a better driver. A suspension mod was a must do thing on this car otherwise it was a unacceptable on a track. I remember the first moment I hit it hard after leaving the dealership at the traffic light, wondering "why am I looking at the sky" . The car would squad and dive so bad instock form it took me less than 4 days after ownership that I ordered by coilovers. Anyway all in the past now. Go EvoSiyah isn't the z4 m coupe better than the z3? that's what I'd expect, same inline 6 as the m3.
