I had a friend that was so Anal Retentive about every ounce of excess weight on his 68 Notchback Barracuda street/strip car. He removed all seam sealer, any bolt or nut not needed, any extra wires in the wiring looms, cut any bolt so it had just enough threads engaged, on and on.... So he'd waddle his 375 pound body out to get into the car. He died at 42.
