Gain the ability to run bigger wheels and tires on your 1979-1993 Fox Body Mustang with Detroit Speed's Rear Mini-Tubs! These inner rear wheel housings will allow you to fit up to a 315mm wide tire without messing up your outer fenders or modifying your frame rails. Constructed from 18-gauge steel and laser cut for accuracy, these mini-tubs are a perfect fit and retain an OEM appearance. Additional material is also provided if you need even more depth, but this will require modifying your frame rails. DSE also includes a seat belt relocation bracket and hardware to retain your factory rear seats. This is also the perfect upgrade to perform after installing your DSE rear coilover conversion kit!
