I had some concern too but fortunately no modifications or impact to the ABS system, CRAWL, or DAC. They continue to work as factory. I've had to do emergency stops since install and the brake balance and ABS function work well, even with 35s.
Just completed this project today. Easily one of the best mods yet on this heavy beast. Pedal feel is much better and stopping power seems substantially increased. Kicked in ABS once when bedding the new brakes. Definitely one of the most substantial upgrades you can do that gets daily use.
