Give your 1979-1993 Fox Body Mustang a modern makeover and improved performance with Detroit Speed's Bolt-On Rear Coilover Conversion Kit. This kit includes everything you need to ditch the outdated and lacking rear suspension your Mustang came with from the factory in favor of adjustability, increased wheel and tire clearance, and a sleek, show ready look. In this kit, DSE provides their "Detroit Tuned" valved JRi double adjustable shocks, coilover springs, and all necessary hardware to relocate these parts further inside the vehicle, unlocking options for larger tires, mini-tubs, and a custom 3" exhaust.
Bolt-On Coilover Conversion: This kit relocates your rear springs and shocks to the frame rail using laser-cut brackets to ensure maximum structural integrity. The space gained from doing this will allow you to install DSE's, or other aftermarket Mini-Tubs to run up to a 315mm rear tire; perfect for those making high horsepower and need the added traction for the street or track. This kit is compatible with your OEM frame and axles making it a true bolt-on solution.
"Detroit Tuned" Shocks: DSE ships this kit with their custom valved "Detroit Tuned" JRi double adjustable coilover shocks for a balanced, adjustable ride. These rear shocks are JRi's most race-winning offering with a large range of independent high and low speed rebound; perfect for the street, track, or autocross course. Ride height can also be adjusted, and you can even swap the included springs for any 2.5" ID coilover spring of your choice.
