They may have, first full quick stop in the SD. Thankfully lower speed and positive outcome. I know the advantages of the ABS, as the goal in stopping is to not lock up the tires as the loss of traction actually increases stopping distance. The distance traveled until stopping was a lot farther than the rubber left on the road.
I will do some more driving in the SD, about 6.5k on it so far. I just know that often OEM is not the best and for the small price of the upgrade, if it helps in any future incidents, it is well worth it.
Most of my brake upgrades in the past have been on my motorcycles, including my Hyabusa that I road, tracked and used to teach MSF courses for the AF when I road still and my Jeep build which was a necessity to upgrade when I jumped up to 37's.
I see it as not much different than upgrading tires. They all roll and stop, but if a different tire provided better traction, it would be another area to upgrade. And yes, that is on the radar too, but so far I've been impressed with the Duratracs through the winter, towing and DD. Previously have been a BFG guy.
