I think I've read some contradictory stuff about MRC. Please clarify.

1. Is MRC available on non-Z51 vehicles?
2. Is MRC standard on all Z51 vehicles?
3. Is the ride comfort comparable between a Z51 vehicle w/ MRC in Tour mode and a non-Z51 vehicle?
4. Are the tires with the Z51 option lower profile than the non-Z51 tires?

#3 - I can't say for sure, but I had 2 C5s - 1 w/standard suspension, 1 w/standard suspension and MRC. With the MRC in tour mode, it felt the same as the 1 w/standard suspension only. I would think that they would have designed the tour mode of the C7 Z51 MRC to be similar to the standard suspension.
