than this in the rear it is possible to use aftermarket 10.5" wide, 27mm offset wheels if the axles and
caliper brackets are changed so that the rear is the same width as the 87-93 rear ends. See the table
above for different width wheel backspacing.

Performance Modifications

The following modifications and set-ups fall under the category of getting more horsepower from your
engine and making your car perform better. You will find a hundred people a day that will tell you what
you've got to have. We just want to start you out with the easy modifications that net large returns
without large cash outlays or serious changes to the stock motor and drive train. Remember that a 2,100
lb. car stresses the parts less than a 3,100 lb. Mustang does, so all of the components will last longer and
can take more abuse than they did on the Mustang. Check out www.factoryfive.com to see what we
offer.
