I've been lookin at fitting some 4 pots on mi XR2, but all the usual suspects seem to stop at 283/285x20 Disks, i'd like to fit 300x24 does anyone know of a company I could try? I've checked Rally design, Hi spec, and a few normal retailers...

I have 16's so 300mm will fit.

 

Could possibly get you a 315x28 4 pot kit. I know it fits the ERST just checking for XR2 for you.
