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

Really once you start tuning either car it is nulled out performance wise. The Nismo tune from factory basically is a couple minor tweaks which is paired with the exhaust. One reason why people say if you are going to go crazy modding it might be best to jump on a base/touring with sport and skip the Nismo.

I've said that before. If people want to heavily mod their cars as in body kits and new rims and so forth, they should get a base/touring. People that bought the nismos love the body and rims not because of the HP increase. No nismo owner in their right mind bought the nismo just for that 18hp increase.

I love the way my car looks over the fangs. I love my rims over the sports package. That is the reason why I bought it and it is the same reason why many others bought the nismo.

hmm, i thought HP was affected as well. I remember a while back a buddy of mine dyno'd his LS1 with chrome corvette rims (heavy) then he took them off and put stockers back on and made a gain of about 15ish...significant

Were the two rims the same size? I know in the RSX community when people went from 16" rims to 17", they lost HP. No idea what lighter wheels do for HP wise. I just know losing some weight will always give better performance.
