And flexes - I'd be more comfortable with 2mm semi-hard.

NS4 (in old money) or 5251 in new money is the usual recommendation.
1050 is too soft I think.
2-3mm for the floor (though 1.5 has been used, and is I think the thickness westfield/caterham use).
1.5 for the side panels is fine.

I used NS4 and regretted it! Way too stiff to work with. The bonnet particularly was a nightmare. The ratchet strap forming method didn't
work at all - sprung almost completely back. In the end took all mine and my dads strength to bend it round a local lamp post and we were unable to
get good control over the bend or do much about it afterwards. Similarly forming 90 degree folds was horrible too.
Use 1050!!

18 gauge NS4 is fine for the floor but it should be bonded with a good quality panel adhesive to the frame and riveted with 4 or 5mm rivets at 50mm
centres. Monel rivets are ideal as they will prevent electrolytic corrosion. NS4 is an alloy and very tough and as has been said not the greatest for
forming but great for floors.
20 gauge,1050A which is pure aluminium is fine for the sides and it can be fairly easily dressed around the chassis tubes particulary if annealed.
NS3 18 gauge would be good for the bonnet.
