and then theres the problem of galvanic reactions when using ally floor rivetted to steel chassis.
after a period of time the ally floor could fall off as the rivets corrode and eventually disapeer
my floor is steel welded on as above
other people have rivetted ally floors and theyre fine too
if you have the steel weld it on im sure it will make an excellent floor and cost nothing.
many kit producers also weld in floors im sure theyre not all wrong

It is well known that the chassis with welded steel floors have the base of the chassis tubes rotting out after a few years. This is exactly why the 750mc recommend riveting the steel floors to the locost race cars. Especially after what was seen on some of the early cars.
If you are going to weld the floor on the ideal way is to cut the sheet so it sits inside the chassis so there is no overlap of the floor sheet and the chassis tube. This then requires the whole of the sheet to be seemed. Not really a good idea as it distorts the chassis quite badly.
