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, it improves suspension geometry, ride quality and driving characteristics without sacrificing appearance. With the Mini-Tub Suspension Kit, you can expect improved traction, 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 Rear Coilover Conversion, Swivel-Link™, Rear Sway Bar, and Adjustable Track Bar Kits.
The 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 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 coilover conversion is complete, Detroit Speed Mini-Tubs may be installed in the car at any time.

Features & Benefits:
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, 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.

Features & Benefits:
- 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)
- Laser-cut brackets compatible with original frames and axles
Features & Benefits:
- Bolt-on Detroit Speed Swivel-Links™ are stronger than factory control arms and eliminate bind, allowing the rear suspension to fully articulate
- Easily adjust wheelbase and pinion angle without unbolting Swivel-Links™ from the car for improved traction and lower driveline vibrations

Features & Benefits:
- Bolt-on tubular sway bar mounts directly to the chassis and axle - more effective than factory bar
- 3/4" sway bar diameter
Features & Benefits:
- Bolt-on track bar adds a critical link to keep the rear axle centered and stable during hard cornering - absent from the stock Fox Body Mustang
- Provides clearance for custom exhaust up to 3" (depending on tire and mini-tub width, fuel tank modification may be required)
- Improves vehicle's handling by locating the rear roll center 1-1/2” below axle centerline
- Laser-cut brackets compatible with original frames and axles
