Remember seeing something about this.

Fed up with the p!ddly little reservoir in the vRS.

Is there anything that will directly retrofit? And parts numbers thereof?

Cheers guys...

You're thinking about the washer bottle for cars with headlight washers, think its a straight fit only have to block up the hole for the headlight washer

Yeah the washer bottle for those of us with headlamp washers is 5.5 litres. I wash my windscreen several times EVERY time I drive as its habit nowadays and it takes months to get through the dam thing. It is very hard to fit the lower bolt though so I have just fit the top bolt. Its still plenty secure.
