Spoke with Chevy Chat about the ZR2, the rep gave me this link for ordering info:
Model Information - Online Ordering Guide
"ZR2 ordering will be available March 16, 2017."
I'm starting to lean a lot toward the ZR2. When I price out a Z71, I am pretty much at the $40ish that the ZR2 has.
The ZR2 has all the offroad stuff (DSSV, wide track, lift, front/rear lockers, rock rails, high clearance bumper, front skid plate, unique rims, AT tires), and leather, wireless charging (not available on other trims, but probably the same as Canyon Denali), and all for only a little more than a Z71.
I am hoping supplier pricing will be similar to the other models as far as difference from MSRP. (Or that the dealer can beat that price)
I think I would only add the Nav/Bose (not sure I want to mess with all that goes into upgrading the non-nav system), and quad folding tonneau cover (probably after the fact).
It is odd that it lists the tires for the ZR2 as 255/65/17, but all pictures show 265/65/17 (which is 30.6" not "31", but I guess if you round up it is, right?)
With the lift and high clearance bumper, I don't see why 265/70/17 wouldn't fit. The spare is listed as 265/65/17 though, so I think the 255 is just a typo.
I'm interested to see a winch bumper for these though, but other than TL-4R projectors, LED light bars, I don't know what else I would do to it. If I got the Z71, I would want to change so much, the ZR2 looks to be less in the long run for me.
