89 fzr1000 wheel swap options

[coops]

Hi there. Been a while. Giving my 1000 race bike another birthday. Lots of engine work and so forth. But I think a big improvement would be light wheels. Without spending thousands on new carbon fibre (magnesium is banned in my class) just some modern wheels would be good.
Maybe 2007 onwards.
Anyone here know what might fit? Disc size has proved to be a problem, most brands have reduced discs down to 310mm. I don’t want to re hang the calipers as I am at my brake limit as it is. Spacers and things aren’t a problem for me, I work in a machine shop. Rim widths must stay the same.
Just thought I would ask here. Might get lucky.
Cheers
