Races are won in the turns and on the binders 

The strong Challenge chassis is complemented by an outstanding and proven suspension and the ability to use a wide array of excellent brake packages.  Suspension design and engineering is an extremely challenging endeavor.  Over the years we’ve found what works best in the real world of racing.  You can’t get lucky and you can’t say it works unless you prove it.  The only way to prove it is at a track and under the most extreme circumstances over many, many years. 

Our engineering team has paid it’s dues. 

Front Suspension

Up front, the Factory Five Racing Challenge kit comes with a fully independent tubular front suspension with unequal length upper and lower a-arms and high-end Koni or Bilstein brand single-adjustable coil-over shocks (say that three times).  Our car has earned huge praise and recognition for its suspension which delivers razor sharp handling and a comfortable ride.

Unlike the Mk3 kit whereby customers can use the front lower control arms from the Ford Mustang, the challenge kit includes the optional tubular lower control arm.  The front suspension components are well engineered and bolt-on with ease. 

For brakes the world is your oyster.  Spec legal cars in the FFR-NASA Challenge seires must wear Mustang brakes, but open classers and non-spec racers have the full aftermarket of Ford brakes to choose from.  The big Mustang disc brakes are excellent. 

With the Challenge kit, we supply the coil-over shocks, coil springs, custom mounts, spindle brackets, and upper & lower A-arms with ball joints and fasteners, all ready to bolt together.

Rear Suspension, FFR 3-Link for Pure Performance

The Challenge kit is set-up to utilize the 3-link suspension. The 3-link suspension is a great example of how racing and product development go hand-in-hand.  After the inaugural season  racing our Challenge Series cars in the Mid-Atlantic and West Coast series in 2000, we found the standard four link suspensions had a tendency to oversteer (similar to Mustangs) when pushed to ten-tenths competitive driving.  Our engineers began working with customers, racers, and the team at the Bondurant School to develop a more neutral, racer-friendly suspension.

After more than six years of racing action and thousands of hours of brutal track testing, the FFR 3-link is recognized as a proven and worthy rear race suspension.  It works wonderfully, aiding hook-up, eliminating bind and provides an amazingly predictable ride whether you’re at the track or on the street.
