Rear brake options for RC24/26 wheel swaps

Oh, you're the best mdude, but I am rich in those parts. If any body else is contemplating these kind of mods (and I highly recommend you do), consider speaking up. F3 is the one like this obviously. F4 might be a really good candidate if you wanted to weld a lug on the swingarm for the slot in the bracket, which is inline with the axle. As for spacers with that bracket... uncharted.

I actually contemplated adapting the F4 unit for the VT250R rear disc conversion, as it also has a lug on the swingarm for the drum brake panel in line with the axle. But the clearances starting getting concerning on the much narrower VTR swingarm.
