Give your Fox Body Mustang the ultimate rear suspension by converting to a independent rear suspension system for the 1979-1993 Mustang!
The entire rear suspension of the Cobra is attached to a steel subframe, which in turn is attached to the car with just four rubber bushings. The rubber bushings deflect under load, leading to wheel hop and less predictable handling. Changing most of the stock bushings to stiffer bushings will make the suspension much more predictable as well as fix the massive wheelhop issue specific to the independent rear suspensions.
A great upgrade to not only help with alignment but eliminate excessive bumpsteer. Fine-tuning the suspension qualities to ensure that you get down the road 100% in control of your Mustang. Whether you just need to replace the worn-out factory units or looking for an adjustable unit to further dial in your sway bar preload.
More than likely, you will need new brakes for your Fox Body as the IRS has specific calipers and large 11.65” rotors. You can choose from stock replacements or a performance upgrade for your swap. Along with swapping out the other brake component to convert to rear disk if you haven’t already.
New shocks are going to be a must for the swap as the solid axle shock won’t attach to the new IRS cradle. Offering upgrade replacement all the way to fully adjustable shock helps you dial in the ride quality and performance you want out of your swap.
Refreshing the wheel hub and bearing in your new IRS is an easy insurance to prevent future issues. With unknown miles and a hard service life, your factory hubs and bearings are small parts that make a big difference to the quality of your Fox Body IRS swap.
