Anybody running the RMS AlterKation? Was it really worth the cost?

I have one in my 67 Barracuda. It is a great system. I only have 15 inch wheels on mine so I was limited on front tire size. I have driven a 66 with 17 inch wheels on it and the difference is quite impressive.

On the other hand I have a 70 Road runner with firm feel torsion bars and QA 1 control arms and it handles amazing so nothing wrong with a fresh stock system either.
