Adjusting Koni coilover - wrench size?

[brinboston]

Hey everyone...

I have a set of koni coilovers on the car (98 A4 2.8q) put on by a previous owner and i did not get the wrench that came with the kit. I need to raise the car cause its too low after i fit bigger rims/tires on it. does anyone know what size spanner wrench is needed to adjust these? Thanks in advance for your help
