1979-1993 Ford Mustang/1979-1986 Mercury Capri

What sets this Detroit Speed rear suspension system apart from the others is all the considerations that went into the design. Not only does this kit fix common issues seen in the Fox Body platform, but it also improves suspension geometry, ride quality, and driving characteristics without sacrificing appearance. With the Speed Kit 3 Suspension Kit, you can expect improved traction, increased stability, and lower driveline vibrations, giving you more confidence for spirited driving. This kit was designed for daily driving, dragstrip, autocross, and track use.  This kit combines our 1) Rear Coilover Conversion, 2) Swivel-Link™ Rear Suspension, 3) Rear Sway Bar, and 4) Adjustable Track Bar Kits. 1) The Detroit Speed Rear Coilover Conversion Kit allows the latest in coilover spring/shock technology to be bolted onto any Fox Body Mustang, bringing your classic's handling and ride into the 21st Century with our "Detroit Tuned" valving. The springs are removed from the lower control arms and shocks mounts are relocated into the frame rail for maximum strength and wheel/tire clearance. Once the coilover conversion is complete, Detroit Speed Mini-Tubs may be installed in the car at any time. 2) The Detroit Speed Swivel-Link™ Rear Suspension Kit eliminates bind and allows the suspension to fully articulate without the use of noisy spherical rod ends. Swivel-Link™ rear links allow for easy pinion angle adjustment without unbolting from the car for improved traction and lower driveline vibrations. The Fox Body Mustang Swivel-Link™ Kit comes with new hardware and directly bolts on to replace the factory links. A coilover conversion kit is required before installing the Swivel-Link™ kit, as there is no spring perch on the links like on the factory arm. 3) The Detroit Speed Fox Body Mustang Sway Bar offers multiple advantages over the non-effective stock rear bar. Detroit Speed sway bars attach to the rear end housing and the frame rail, whereas 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 and eliminating binding through the range of rear suspension travel. 4) The Detroit Speed Fox Body Mustang 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. The addition of a Detroit Speed Track Bar to the Fox Body Platform will prevent the axle from wandering unpredictably. The track bar connects 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 attach utilizing holes added into the frame rail as well as U-bolts to the factory 8.8 rear axle.

Features:

• Bolt-on coilover conversion relocates the springs/shocks to the frame rail for maximum strength and wheel/tire clearance

• "Detroit Tuned" coilover springs/shocks optimized for modern ride quality, handling and ride-height adjustment

• Provides clearance for custom exhaust up to 3" (depending on tire and mini-tub width, fuel tank modification may be required)
