is putting the z-cars kit into a fibreglass mini any different to a normal one? because at the moment im thinking up a plan which mite be quite similar to yours but with a FRA mini shell
Not hugely different but obviously it depends on your bodyshell.
With mine the kit was built as a one off for the car mainly due to the height difference, but also due to the fibre glass floor. The "feet" of the kit are much bigger than the normal kits to spread the weight better and are sandwiched with another plate underneath the car. Other than that I'm pretty sure it's much the same.
I would say some things are trickier as you can't just weld it like you would a normal mini but I am trying to learn more about glues and bonding :grin:
