Roll Design +3 A-Arms

Does anyone know why they say to run the 400ex spindle and brake setup for these a-arms? Or can you use the 88-89 250r spindle and brake setup?

I can tell you that when I switched my 89 250R spindles for the 400EX ones on my +2 Laegers a arms, I had to readjust the camber setting. This was because of the difference in geometry between the two types of spindles. You can use the 250R calipers on the 400EX spindles if you buy caliper adapters from Baldwin Motorsports. I would think 89 250R spindles would work with the Roll a arms if you set the camber up.
