Looking on the EBC site they do not list the Aero chassis.
Looking on ebay they do seem to list a part that is suitable.
https://www.ebay.co.uk/itm/DP4197-2...t-7-Race-upgrade-X-Bow-Aer/401020494275?IIRC the Aero offers two calipers on the back, handbrake and main brakes. Might be worth checking in case a reseller offers the wrong set due to lack of experience.
I have sent an email to my EBC contact to ask.
