Hi folks,
This is probably old news to a lot of folks, but I think worth posting just in case it does help someone. To be honest it's actually used on an Elan, but the principles apply equally to the Europa and other cars if you decide to fit suspension with adjustable spring platforms. The manuals do state the ground clearances needed but in my case I had a modified chassis and they no longer applied.
It's a DIY laser level, bought cheaply off Ebay for some tiling I was doing a while back. It has 2 spirit levels to set it up and can output either a dot or line. Using the line it's very easy to set the wishbones on the suspension horizontal which at least ensures you have both sides of the car something like right to start with. The Europa has canted lower wishbones but going on the manual the inner & outer bolt holes should be in the same plane in practice which sounds about right, so the principles still apply. (confession - not used it on the Europa as that's still on OEM suspension, so I can't be 100% certain)
The second shot is in use, and with a bit of imagination you can just make out the red line on the chassis mounting pin heading along the wishbone. In practice it's very clear and easy to adjust.
