So I got a lend of my mate's car scales.

The rear right one is dodgy but I worked out I add about 60-70kg based on testing it with know weights. The others are spot on.

Also 20kg of parts are currently out so that gives me a total of 960kg curb weight.

Also they have a weird front/rear bias of about 35/65. Hate to know how ass heavy a bug is since they are shit loads lighter up front and comparable at the rear.
