F20C got it the closest.

I'm full of M-Spec info but to lazy to type up all of the techinical goodies. If you read the newest issue of
evo magazine (issue 35 I think). I test drive it. It's supposed to be the best R34 out even edging the V-Spec2. evo gave it 4.5 out of 5 stars if my brain still works.
EDIT: opps... I didn't test drive it evo did.

sorry if I confused anyone.
