The show itself for being a self-parody. In-show, Kyousuke proves his love for Zonette by taking on the bad guys- and the Monster of the Week- unmorphed.
A CMOA for the series as well, on the special effects front: Episode 32 has Red Racer convincingly fighting that week's monster on top of a set of batteries on RV Robo's waist - impressive for a TV show in 1996.
Exhaus attempts to drop the Bowzock's base onto the Earth, only for it to be stopped and put back into orbit. You're probably expecting this to be a combined effort of all the team's mecha, a la Mobile Suit Gundam: Char's Counterattack, right? Nope! Turns out that it's Signalman and Sirender all by themselves!
Carranger has an awesome moment where Kyosuke who Zonette hates in his civillian form yet loves when he is Red Racer proves how much he loves her by fighting AND defeating one of the monsters in human form
