"1/8 inch think support pads on the top or bottom of the floor or sill in a sandwich construction "
I was going to bend a plate to follow the contour of the heavier frameish part of my chassis to spread the loading and tuck the cage nicely, but this seems to encourage me to just head strait for the flat part floor where is easy to sandwich plates. Does it have the be sandwiched with bolts and welded?
Hate to chime in on this. I know this question was posted in the ECTA Rules Question.
Don't have an ECTA Rule Book laying around, so I am not sure if they have the same requirements as the SCTA Rule Book spells out.
Just in case you are intending to run at an SCTA sanctioned event, you may want to keep the following in mind:

the roll cage structure and braces shall have 1/4-inch thick support pads on the top and bottom of the floor (or sill), in a sandwich construction and shall be of sufficient area to support an impact load equal to the weight of the car. For cars weighing ....
I believe you are building a unibody car, correct?
Of course, this is just my two cents and I am sure Joe Timney would know for sure. Or you can always contact Steve Davies at the SCTA, to get his guidence.
