General Mustang Tech & ChatThis Forum is for General Mustang Tech that fits both suspension, exhaust, wheels, tires and more. General Mustang chat / banter is welcome as well.
Having been there and done that I'd say stick with a better fitting 26x10 and gear it for that, it's a far easiler fit. 3.73's and that tire should go 124-125mph at under 6200rpm and if you plan on more drop down to a 3.55. A 28" slick is a huge tire to pull out of the hole and out of boost the small motors just don't pull that tire as well. Gearing will help but you have to watch trap rpms. If you do go with a 28" slick, get something narrow. I swapped to a set of 28x10.50's and my old blower combo sucked. Pooch out of the hole and lost a bunch of MPH up top. Back to the smaller 26x10's and all was well except the high traps rpms and limiter interference so in went the 3.55's with no real side effects but 30-400rpm less in the traps.
