Can anyone say if the engine mapping changes in the 2019s is actually noticeable? Or what is actually different? I’ve read the articles and understand the hardware changes between the years (sway bars and stiffer rear hub), but can’t find any other concrete info. The sway bars can be bought from the parts counter for a whole lot cheaper than the price delta between the years. Interestingly the rear hub appears to be the same part number based on my quick search. I’m starting to wonder if holding out for a 2019 is worthwhile, or if I should save some money and go with a 17 since I would immediately install SOS downpipes and JB4 anyway. It appears low mileage, fully loaded 2017s can be had for under $130K. Any insight would be appreciated.
