|The optional ultra-lightweight completely redesigned, high-performance, low-profile Alpha body with super-smooth airflow and all-new downforce areas. The Alpha body gives increased steering & stability while also improving handling in jumps. Lower weight reduces the roll of the car and improves rotation in corners.
The front part of the body has a new high-downforce area. The sides of the body have upper downforce areas to generate more mid-body downforce, and the straight sidewalls improve stability. The upper part of the body was redesigned with a smooth flow channel.
Different XB4 bodies are available in different thicknesses for fine tuning the performance of the car.
