Dr30 Brake Upgrade

[scr33min']

Ok, so I'm over the sloppy stock brakes on my dr30 and I'm looking for an upgrade.So I was thinking of keeping the stock discs but fitting r32 gts calipers over them, but I don't know if the mounting holes lone up.I know if I convert to s13 knuckles I can fit a wide variety of brakes on no problem but I'm not. Looking into going that far just of yet as I might as well get some s13 coilovers to fit at the same time and that then increases the budget more.

So are there any simple upgrades I can do to the brakes without having to change knuckles at all?Cheers, Michael
