I thought at least one person would catch that my weight totals added up to 101 %
I got my F to R weight measurements from a friend's very early Superformance (below sn#80 although I don' recall it at the time)
His car weighed 2490 lbs with a 1/4 tank of gas using a 4 pad weight scale. 47 F and 53 R
I know original Cobras have much different weights and the CSX 4000 and Kirkham cars are much closer to an original's specs.
To answer the original question I really don't have any first hand experience or any knowledge of wether removing 100 lbs would have any adverse handeling effects on an original Cobra.
As far as my aluminum engined car (SPF) is concerend, I will say that I plan to relocate my upper front shock mount 1.5 " higher and change my front springs to Eibach progressives with 50 lbs/in less spring rate, increase the rear sway bar .125", lower my tire pressure 5 psi in the front tires, and add 1/4 degree more pos caster in the front alignment specs.
I will then boldly go out and test my modifications to the limit of sanity.
If you fail to recieve an analysis of my experiments or fail to hear from me in the future, you all can assume that my changes didn't work as well as planned and what's left of my car should be for sale to the highest bidder
