Stop on a dime… And get change

The ugly truth is that most kits, hot rods and customs handle terribly. The artistry and strength of the Factory Five Roadster chassis would be a waste without an equally well-designed suspension. Computer simulations and hundreds of hours on the track under the most extreme conditions have helped our engineers design a world-class suspension that simply works great.

Front Suspension Base Kit
• Fully independent front suspension utilizing unequal length upper and lower a-arms
• High-end Koni mono-tube adjustable coil-over rod-end shocks
• Uses donor Mustang front lower arms, spindles, and brakes
• Optional tubular steel lower control arms

Front Suspension Complete Kit
• The Factory Five Racing Mk4 complete kit includes the entire front suspension assembly and Ford brakes.
• Includes Ford GT brakes with 11” rotors, twin piston calipers, and stainless steel brake lines, fittings, and fasteners
• Includes brand-new spindles and tubular control arms

Brakes/Wheels
Rear end and brakes can be used from a Mustang donor car. We alsosell brand new 8.8” Ford rear ends with Mustang brake kits.
 

We offer an optional Halibrand replica wheel that is affordably priced and in the correct sizes/backspaces to work with our car.

Rear Suspension

The Mk4 Roadster Chassis Kit is delivered ready to accept bolt-on rear suspension components in one of three (3) rear suspension configurations:

1. Four Link Rear Suspension
Our standard 4-link suspension comes with custom anti-squat geometry and ready to accept Ford Mustang 8.8” solid axle donor rear suspension parts. About half of FFR Roadster kits are shipped with the affordable standard 4-link rear suspension, which is a great performance street car suspension.

2. Three Link Rear Suspension
The upgraded 3-link rear suspension is standard in Mk4 complete kits and all FFR Challenge Series cars. It includes the frame brackets, panhard rod, control arms, coil-over shocks and springs. Recognized as a proven and worthy upgrade to the standard Mustang 4-link, this suspension eliminates any bind and provides an amazingly predictable ride at the track or on the street.

3. Independent Rear Suspension
Our Independent Rear Suspension upgrade is designed for those looking for the most comfort and authenticity, and can be added to either the base or the complete kit. It includes a welded-in cage, upper and lower tubular control arms, high-end Koni mono-tube rod-end coil-over shocks (matched to the fronts), and custom assembled axles and CV joints.  The IRS option for the Mk4 kit requires the 8.8” center section (from a 1989-1997 Ford Thunderbird), rear spindles, and brakes.
