Mazda Miata NA and NB Rear Grip Kit

Just Engineering Mazda Miata NA/NB Rear Grip Kit

Traction issues are a common hurdle for high-horsepower Miata builds, especially when forced induction enters the equation. Developed to solve real-world grip problems, the Just Engineering Rear Grip Kit is a comprehensive package designed to keep your tires planted and your power on the pavement.

This kit fundamentally improves rear suspension geometry by correcting the lateral roll center. By raising the spindle 1” directly within the knuckle, Just Engineering has created a solution that allows for a lower ride height without sacrificing handling characteristics or mechanical grip.

Key Features

• Roll Center Correction: Raises the spindle 1” in the knuckle to optimize lateral roll center on lowered vehicles.
• Advanced Pivot Design: Features a redesigned lower pivot with a separate ball joint and toe link for superior control.
• Independent Adjustments: Because the two ball joints are positioned in line, camber remains stable even when making significant toe adjustments.
• Adjustable Toe Gain: Easily fine-tune your toe gain (positive or negative) by simply modifying the spacer stack on the knuckle toe adjuster.
• Enhanced Traction: Specifically engineered to help high-torque and supercharged applications put power down more effectively.

Fitment / Applications

• Mazda Miata NA (1990-1997)
• Mazda Miata NB (1999-2005)

Notes

• The new knuckle is dropped by 1".
• Installation requires the supply and installation of a new OEM wheel bearing.
