Anyone local to me have a coilover adjusting tool that is`nt a hammer?
didn't you get the tool(s) with the coilovers? I got a couple of C-Spanners with mine, I just keep them in the small toolkit in the boot.
Maybe you can use a centre-punch type thing and a hammer? Not exactly the scientific approach, but I used to use that on bikes (bicycles) all the time when I didn't have the right tool
