Bad Shoppe’s new unboxing puts the red Yokomo SD 3.0 Competition Spec kit on the table before the promised build, shakedown and MST RMX 4 GT comparison.

Yokomo's archived monthly new-product pages date the DP-180SX to 6 February 2004 and put it on the MR-4TC SD, the shaft-drive touring car the company had launched eleven months earlier. The kit's parts list, not its age, is what still matters.
