That's not necessarily true. When I built my car years ago I thought the same thing. After years of racing on bad to mediocre tracks. I decided to try and get the front to rear weight % better. So I undid the mistakes that I made when I built the car. I started by putting a glass rear window back in, then I put a steel bumper with all the brackets back on. And last I put a steel decklid back on to get to 54% on the front.
