"No my car is faster than yours"
You can have variances of over a second for 0-60 times for different magazine articles. I remember when the EVOs and STIs first came out, magazines said they were 0-60 in 4.5 seconds, later that went to 5.5 and now seems to settle in the low 5s. -WHO CARES?
I personally dont care much about those 'raw' numbers. Heck, even lap times (which are a better gauge), still isnt that good when you take into consideration all the variables in terms of weather, tire condition, driver (BIG variance), etc...
My full interior stock NSX (with bigger 17-18" wheels - heavier), 1/2 tank of gas, sub, amp, and with me in it weighed in at 3,050lbs.
Early NSXs had 15" wheels - hard to fit a bigger caliper with the suspension geometry, wheel sizing, high offset at the time. Larger rotors and calipers won't necessarily make you stop in their 1-stop panic brake exercise (again useless) any better, but the NSXs stock brake system holds up to track abuse pretty well as is.
