The new bumper now is with more down force. It will result with more steering. The rear wheel arch surface was also extended. It not only increases the strength of the rear end, but also makes the body-shell able to move forward to increase steering.
The standard version GT3-GBS body was built from 1.0mm high quality polycarbonate sheet, and the light version was with 0.8mm. Both versions include rear wing, wing screws, decal, and window mask for painting.
Note: GT3-GBS Body-Shell is sold in clear unpainted.
