I think I am the minority but the FBO m3 is more than enough power for me and for street driving its already at illegal speeds in a blink. I like being able to wind out 1st,2nd and sometimes 3rd and enjoy the sound and experience of everything happening. With a SC it all happens so quickly and your at speed in a fraction of the time which is cool in its own right.
For me its all about keeping it NA too. I always wanted a high revving NA V8 and would not touch this thing with a SC. I will add a new F80 m3 to the stable to get my FI fix but this baby is staying NA. FBO and approx. 400 whp with a 8600 rpm redline makes for the perfect daily driving street machine!
