AUTOEXE Lower Arm Bar (Rear) for Mazda RX8 (Series 1 & 2, 2003-2012)

Reinforce the rear lower arms to reduce toe change under load, helping stability on corner exit and improving tyre wear.

$300

The AUTOEXE Lower Arm Bar (Rear) for Mazda RX8 Series 1 & Series 2 models (2003–2012) ties the rear suspension pivot points together to reduce chassis deformation under cornering loads, helping the rear end stay more planted and predictable.

  • Reinforces the pivot points of the rear lower suspension arms to stabilise geometry under load
  • Suppresses deformation in the rear chassis area, allowing the suspension to do its job more effectively
  • Provides a more secure, confidence-inspiring feel from the rear axle during turn-in and mid-corner
  • Constructed from high-strength steel to maximise rigidity and longevity in demanding use

You will notice a more stable and predictable rear end during cornering, with the car feeling more composed and allowing earlier, more confident throttle application out of bends.

For a balanced chassis package on your RX8 (2003–2012), combine this bar with the AUTOEXE Lower Arm Bar (Front) and the AUTOEXE Floor Cross Bar.
