But I will run the numbers and check.
Here's what I believe is the math for how the 1G CRX Si/3G Civic Si's got adjusted to their current 1970lbs:

91hp * 1.30 * .98 * 17 = 1970.8

Tom Lamb's letter languished in the ITAC for years. I wrote mine over the winter in support of his and adding some new points of my own. It was well established the old weight was completely arbitrary when the car was moved down from A to B.

BTW, that previous weight of 2130lbs was a power multiplier of 40%+.
