After thinking a little deeper into this, if i remember correctly the NISMO rims weigh something like 20lbs for both front and back...base and sport packed Z's IIRC weigh something like 23ish front and back....that unsprung weight loss could account for the HP diff too. Rim weight makes a difference on the dyno....hhmmmmm intersting
