Fox Mustang Independent Rear Suspension Install



 Irs Fox Body Mustang Control Arms Irs Fox Body Mustang Forward Torque Brace
To secure the front side of the carrier, Kenny Brown's forward torque brace was used in conjunction with the company's aluminum mount bushings. Together, these items are billed to reduce carrier deflection and bushing windup, resulting in reduced wheelhop and improved feel. Putting together the entire assembly requires you to hold your jaw just right, but it generally goes together in a straightforward manner.

Now we're ready for the halfshaft assembly. Note the optional red seal protectors Brian likes to use, which are removed once the splines are past the seal. Insert the halfshaft until the snap ring is engaged, indicated by a slight click.
 Irs Fox Body Mustang Upper Control Arm Mount
Adjusting camber is done via the upper-control-arm mount, which is a distinct feature of the IRS assembly. Stock IRS rear alignment specs are 0.7 to 0.8 degree negative camber, while Kenny Brown calls for negative 1.2 degrees.

An adjustable inner tie-rod kit finishes the IRS assembly before it goes into the car, which Kenny Brown says helps diminish the factory IRS's excessive rear-steer characteristics-much akin to bumpsteer in a front suspension. Begin by measuring the length of the current tie-rod assembly. While you'll need a rear alignment upon completion, mimicking the stock measurement in the new parts gets you in the ballpark.
