By decreasing the weight behind the rear axle you reduce that part of the force vector sum. Meaning the front actually has a greater force on it, since the moment around the rear axel must still be 0.

Greater force on the front, more spring compression.
Even if it raised the car equally I doubt that a 3.5% weight reduction spread across the whole suspension would make any real difference in ride height at all. Certainly not enough to prevent scraping unless you were just touching by a c-hair.
