My SVT UIM was a LOT smoother than the SE UIM that I had on the car during the recent group buy. How to describe it. Say the SE UIM is like concrete, very bumpy. The SVT UIM would be like concrete in your basement or garage floor. Still not perfect but MUCH smoother. Hope that helps a little.

I'm not sure if there were any pictures taken of the differences inside the passages, the only ones I can recall were of the different diameters.
