Eibach 15mm Rear Anti-Roll Kit for 1989-1997 Mazda Miata

Transform your Mazda Miata NA's cornering with the Eibach 15mm Rear Anti-Roll Kit, featuring precision spacers that raise the rear sway bar position. Designed exclusively for 1989-1997 Miata models, this kit restores proper roll center geometry after installing lowering springs. Expect tighter turn-in, reduced understeer, and enhanced rear traction on twisty roads or autocross tracks.

Key Features

  • 15mm Spacer Height: Precisely raises rear sway bar for accurate roll center correction, eliminating excessive body roll from lowered suspensions.
  • Billet Aluminum Construction: CAD-engineered spacers deliver lasting durability and resistance to corrosion under high-stress track conditions.
  • Direct Bolt-On Design: Fits factory sway bar mounting points without modifications, ensuring straightforward integration into stock or modified setups.
  • Motorsport Proven: Developed from Eibach's racing heritage, providing consistent performance gains in handling and stability.
  • Balanced Chassis Dynamics: Pairs perfectly with Eibach Pro-Kit springs for neutral handling characteristics across spirited driving.

Product Notes

  • Ideal companion to lowering springs; use with front anti-roll kit for full balance.
  • Retorque fasteners after 100 miles of driving to ensure secure fitment.
  • Special order item; allow 3-5 business days for processing if not in stock.

Installation Notes
