Since first making the ballast for the racecar, it has gotten bigger wheels and tires, all the aero bits added, the electric power steering column (and the heavier, faster ratio PS rack), and a few Hill Climb safety bits and bobs. With nearly an empty tank, it rolled across the scales about 59 lbs overweight.
1983 lbs, where my class minimum is 1924.
I was able to drop 1 of the two 5/8″ lead plates, and also cut about 1/4 off the other one.
I got down to 1932 (8 lbs over minimum).
I’m generally not comfortable with that tight of a margin, but I never run with that little fuel, so there’s a bit more wiggle room than it would seem.
