I agree, my 2024 GT 10 speed came with 3.15 gears and it could easily break the tires loose .I really wasn't happy with the performance so i purchased a loaded 3..55 differential from Ford performance and had it installed they also programmed the computer so the car knows it has a 3.55 gear...
there is not much difference in acceleration between a 315 and a 355 with stock tires because the tires are spinning but if you have bigger tires with a lot of grip you will notice a big difference !
