This is an optional XRAY NT1 2013 3mm Aluminum Narrow Chassis. This chassis was re-designed to enhance performance in corners and to increase chassis flex and thus generate more traction and steering. The narrow chassis also minimizes contact with the track in corners and will eliminate the feel of the car “stopping” in mid-corner.
The lightweight chassis is CNC-machined from premium Swiss 7075 T6 aluminum and is strategically machined in low-stress areas to make it as light as possible without adversely affecting strength or rigidity. The area below the engine is machined so the engine sits lower to reduce the CG when using the optional engine mount and flywheel. The outer edges of the chassis have been beveled and screw holes have been countersunk to provide a smooth lower surface. The area under the engine features air-flow cut-outs to allow extra airflow to cool the engine.
Provisions have been made to accommodate graphite reinforcing inserts and/or additional balancing weights, front and rear to tune chassis stiffness, balance, and CG.
