Powerflex Black – Adjustable Front Control Arm Rear Bush – Subaru BRZ

The Powerflex Black Series adjustable front control arm rear bush (PFF69-801GBLK) is engineered to provide precise control of front-axle geometry and maximum structural rigidity on track, in rallying and during track days on cars such as the Subaru BRZ, Toyota GT86 and GR86.

Manufactured from the special ultra-stiff Black Series polyurethane compound (95 Shore A), this bush replaces the original rubber component, virtually eliminating deflection and changes in toe/caster under heavy lateral loads or braking. The defining feature of this version (G - Camber Adjustable) is its integrated adjustment mechanism, which allows front camber to be adjusted on the vehicle by up to +/- 1.0°, enabling extremely precise suspension setup to optimise the tyre contact patch when cornering.

The component corresponds to position #1 in the front suspension exploded diagram and is supplied as a pack of 2 (the quantity required to complete the vehicle's front axle).

Note

As these are extremely stiff Black Series (95A) components intended for competition use, installation can increase steering response and may cause a slight increase in vibration/noise (NVH) transmitted to the cabin.
