If you are refining a T4'15 for club or regional events, the XRAY 301138 chassis is a compact way to improve on-track response. Crafted from Swiss 7075 T6, the 2mm aluminum sheet increases chassis stiffness and helps the car react more precisely to driver inputs. The black coating provides extra surface protection without adding bulk.
The XRAY 301138 is CNC machined from premium Swiss 7075 T6 and kept to a 2mm thickness for a balance of strength and lightness. Its slim outline enhances turn-in and mid-corner feel, making setup changes easier to dial in. The finish resists wear from track debris and routine handling.
This aluminum chassis works across low, medium and high traction tracks, allowing drivers to tune roll and steering characteristics to suit surface grip. It complements common T4'15 suspension and weight distribution adjustments to help achieve consistent lap times.
