At our GM meetings, engineers are quick to point out that the size of the rotor has little to do with the stopping distances. There are many other factors, including The number of pistons. (We use 4, they use 2). Ditto the size of the ring and pinion gear.
That rotor thing has been an ongoing Ford issue on the SD's.
re: the Rr AC vents. Anyone that's been in a GM product in hot weather knows nobody does AC better than the General. Engineering Certification for GM involves a 50 degree cool-down in 7 minutes.... in Death Valley... in the summertime. That's all product lines, something that gave GM Korea's engineers fits with the Aveo (they had to redesign the dash and HVAC unit).
Who's "they"???
The Tundra uses HUGE 4 piston calipers.
As great as GM A/C is (I'll take your word for it) it's about balance, especially in Death Valley's neighbor, Las Vegas.
In a large cab, there is a huge difference in temp from front to back when just the dash is blowing....
Strange the 800's had rear vents but the "improved" 900's don't....
And while the Eaton locker is a far better diff than the POS the Tundra uses.....it has been proven fragile. (realize that's not a ring size issue)
