Yes, on the metal bumper you do need a bar going across the bottom.

Number 8 in the photo is an example.
Thanks for the info Gary.
adding to Gary’s post, Ital does has the bar and is listed in the parts manual as:
13 – ITL122 – 610mm REAR BUMPER ROD WITH GROOVES-ITALKART – $20.09
That covers the Supersonic V / Supersonic / Rapido, 100/125. Noticed the one from Comet is 550mm. The Ital is 610.
Good info, Tony. Thanks.
