Going to be using it for the first time on the 405 over the Easter break, used it on my old 322 and Disco's, its the 5 rack one so a bit of a beast anyone had experience on the 405?

I had one on my l322

I’d try a dry run ASAP to figure out whether the support straps will clear the rear spoiler

I did not ever bother with the support straps in the past

Ok - I found the 5 bike one a little bouncy without, but maybe your setup is better / lighter

My setup is two adult bikes and three kids bikes so maybe a bit lighter, but i know i should use the straps,
