Speed Kit 3 rear suspension kits from Detroit Speed fix common issues seen in the Fox Body platform and also improves suspension geometry, ride quality, and driving characteristics without sacrificing appearance. They are designed for daily driving, dragstrip, autocross, and track use. DSE Speed Kit 3 bundles Detroit's rear coilover conversion, Swivel-Link, rear sway bar, and adjustable track bar kits. They are available with single-, double-, or non-adjustable shocks. Detroit Speed coilover conversion kit allows the latest in coilover spring/shock technology to be bolted on to any Fox Body Mustang, bringing your classic's handling and ride into the 21st Century with their "Detroit-Tuned" valving. The kit relocates the springs and shocks into the frame rail for maximum strength and wheel/tire clearance. Once coilover conversion is complete, Detroit Speed Mini-Tubs may be installed in the car at any time. Laser-cut brackets are included. Detroit Speed Swivel-Link rear suspension kit eliminates bind and allows the suspension to fully articulate without the use of noisy spherical rod ends. They also allow for easy pinion angle adjustment without unbolting from the car for improved traction and lower driveline vibrations. DSE Fox Body Mustang Swivel-Link kit comes with new hardware and directly bolts on to replace the factory links. Detroit Speed sway bar offers multiple advantages over the non-effective stock rear bar. DSE sway bars attach to the rear end housing and the frame rail, where the stock bar only connects to the lower suspension links. By using the chassis to stabilize the rear axle as opposed to the opposing link, the deflection of the vehicle under heavy cornering is minimized. Detroit Speed sway bars mount with a low-friction ball-style end-link, allowing free articulation of the bar, eliminating binding through the range of rear suspension travel. Detroit Speed adjustable track bar kit adds a critical link to keep the rear axle stable during hard cornering. The factory 4-link is completely ineffective at locating the axle side-to-side as the suspension arms travel vertically, and the addition of a DSE track bar will prevent the axle from wandering unpredictably. The track bar connects to the rear axle to the chassis of the vehicle, which helps keep the axle centered under the chassis during suspension travel. This gives the driver better grip and acceleration off the line and more confidence in the corners. The track bar brackets bolt-on through holes added into the frame rail and U-bolts to the factory 8.8 rear axle.
