Should I use a steel or aluminium floor?
There were concerns about using a riveted aluminium floor, as the floor itself is a stressed part of the chassis. However these concerns can be alleviated by using structural rivets (often called closed end rivets) and a PU adhesive to attach the floor. My analysis showed that an aluminium floor could save up to 6kg over a steel floor so it is well worth doing if you want to save some weight!
