I’m running the same rear tires also ,
26” inch tall. I went with the shorter tire cause I have the 3:15 gear.. thinking of going with the 305/45/17 next season.
This is interesting info !! went with the shorter 275/40/17 Mickey Thompson ET STREET R’ cause I also have the 3:15 rear, figured the 26 inch tall tire would help the 60ft. I do agree it looks kinda silly .. might have to give the 305 tires a try.
used MAK cat-delete offroad pipes for 2015-20 Mustang GT , pipes are in great condition . you will need to buy the extra flange for driver side..
