They are very close. One of them is slightly wider where they mount to the frame

So will they fit and work good? Are they going to handle like crap or will feel the same as 250r a-arms?

They will work just fine. You have to use some shims on the outside of the bushings because the 250R mounts are wider by about 10mm.

That depends. Are you using stock or aftermarket arms?

I guess it depends on who's arms they are. Quite a few aftermarket companies use the exact same arms for the 250R that they use for the 400EX, with the exception of the bushings. In that case, yes, just buy the bushing kit for a 250R. I actually have 400EX arms (and bushings) on my 250R, but with one stainless steel washer on each side of each pivot.
