Precision machined rear mount for consistent Kyosho LAZER ZX-5 geometry

The 3Racing ZX5-09/R20/SI is a precision aluminium rear suspension mount engineered to restore and stabilise rear mounting geometry on the Kyosho LAZER ZX-5. Manufactured to tight tolerances, the part reduces flex and provides a repeatable baseline for suspension setup and tuning. The 2.0 degree option is integrated to let technicians and racers apply a known geometric change when testing handling adjustments.

Engineering and material notes

Constructed from high grade aluminium and finished for accurate seat and fastener interface, this mount offers improved wear resistance over polymer alternatives. Consistent hole locations and faces reduce variation between parts, aiding in setup reproducibility across multiple vehicles and sessions.

Fitment and setup guidance

Designed to locate on the factory Kyosho LAZER ZX-5 mounting points, the mount installs with standard hardware. For best results, torque fasteners to factory recommendations and verify alignment after initial runs. Use the 2.0 degree setting as a controlled change when comparing rear setup variants.
