S197 Solid Axle and Rear Bar Sizing
The S197 Mustang uses a solid rear axle with coil springs and watts-link or Panhard rod geometry depending on the variant. Sway bar stiffness on a solid rear axle affects the entire axle’s roll resistance as a unit. The 27mm BFR65Z provides aggressive rear roll stiffness for track applications where the solid axle is being tuned for maximum performance.

Heavy Duty Construction for Track Use
The heavy duty designation indicates solid spring steel construction of appropriate wall thickness for the 27mm diameter and track-use loads. This is a bar that won’t fatigue under repeated high-load cornering cycles.

Endlinks Included
Endlinks are included with the BFR65Z — no separate purchase required. The endlinks are sized for the S197 solid rear axle geometry and the bar’s connection geometry.

The RallySport Take

The maximum rear anti-roll option for the S197 Mustang. If you’re building an S197 for serious track use, the 27mm BFR65Z is the correct rear bar selection. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
