Powerflex Black Series Front Radius Arm To Chassis Bush – BMW Z4 G29 and Toyota Supra A90 J29
Maximise front end grip, braking stability and steering precision with the Powerflex Black Series Front Radius Arm To Chassis Bush, part number PFF5-5401BLK. Engineered specifically for track, race and rally, these 95A durometer polyurethane bushes with anodised aluminium outer shells deliver up to 300% increased stiffness over OEM rubber, giving you tighter control of chassis geometry under hard braking and cornering. Perfect for the BMW Z4 G29 and Toyota Supra Mk5 A90 J29.
Why choose Powerflex Black Series for your G29 Z4 or A90 Supra
- 300% stiffer than OEM front radius arm to chassis bush for sharper turn in and confidence under braking.
- 95 Shore A polyurethane compound resists deflection and heat for longer term durability.
- Anodised aluminium outer shells further increase bush stiffness and stability.
- Controls longitudinal wheel movement to maintain caster, camber and toe under load.
- Direct replacement for worn factory rubber bushes, ideal for track cars and performance builds.
At Nforcd we have fitted these bushes to multiple A90 Supra and G29 Z4 builds and the feedback is consistently excellent. Customers report noticeably improved braking feel, better mid‑corner stability and more precise steering response, especially on track days and aggressive road driving.
