What a cool car!
I follow along to what you're up to every so often, and man, it is looking good.
I'm no engineer but I did stay at a holiday in express, and while I was there I went to a Good Guys show and had a brief chat with the folks at DSE about the weight distribution of my Camaro which has all the go fast parts from their catalog.
My takeaway from the conversation was that cross weight was far more important to them. This isn't to say that front and rear weight bias aren't important, rather a car's suspension setup must be built around that weight bias.
There are cars out there with near 60/40 and 40/60 splits that handle well.
