Also Dustins car has the Velcro battery straps and not the new plastic holder.

You didn't miss anything,but whatever steering rack Dustin is running you can see it's not the "expensive third party steering" as you can see (BELOW) it's plastic instead of alloy.
According to Todd Hodge -
"Now onto the rack versus the bell cranks. During our initial testing we found that the rack was fine. It gave the appropriate Ackerman we were looking for, which is why we included it on the 22 2.0. After the worlds warmup we tested bell cranks, which actually give the car less Ackerman. Less Ackerman is when the outside turning tire turns close to the same rate as the inside tire. More Ackerman is when the inside tire turns at a faster rate than the outside. Less Ackerman actually gives the car a better balance on high grip tracks, such as the worlds track we are racing on this weekend. When I say better balance I mean that the less Ackerman actually gives us less steering compared to the rack. Now on lower bite tracks the rack will most likely be better because it will provide more steering. We discovered all of this entirely too late in the project and couldn't design, tool and include it in the vehicle quick enough. We are looking at the design right now and will start soon. We are still learning about this and collecting data on the 22 2.0."
As you noted, Dustin's car also has the velcro batter strap - along with the original battery stop. He's also got the gen-1 chassis, as you can see there's no milling of the servo mount area to get the servo lower in the chassis like in the 2.0
According to the U.S. forums the team drivers have just been updating their original cars with updated parts as they've become available, and word has it that he was satisfied with the older battery straps and/or hadn't received the updated parts in time and/or didn't feel comfortable using them for the ROAR Nats this week. He has been using the new cab-forward body and new rear-end geometry (3-hole shock tower and rear arms,
driveshafts/axles).
The 2.0 also include adjustable off-set rear axle where the axle can be mounted 1mm further into the rear hubs, which causes a less supported rear end and increased forward drive out of turns. For higher grip surfaces, a 1mm spacer is included in the kit to allow the axle to be mounting in the same location as the original 22 for a more supported rear end feel which is also the kit setup.
