Question axial versus radial electrolytics

I am a first time poster from the Automotive world, and this issue is very important to our products. Most electrolytic cap suppliers have the radial parts, and many do not have the axial parts. I was told these two statements by one of the Axial suppliers. Does anyone out there have supporting data for this?

1. An axial capacitor can handle roughly 3x the ripple current of a equal sized radial part.

2. A radial part is much worse for a high vibration environment versus an axial part. It is quite difficult to make a 20G radial part where as an axial part can be made to handle 50G+.
