at right about 1:36 of this video, when they are adjusting the rear shocks, you can see two or more blue cylindrical canisters up underneath the trunk area that appear to be connected with braided lines. what system is this?

(sorry wouldn't know the first thing about posting a screenshot here lol)




is it fire suppression? suspension related?

thanks for any info
