Seat Backrest Raising Kit 50mm

The Jass Performance Seat Backrest Raising Kit is a right-side upgrade engineered to enhance comfort and driving ergonomics specifically for lowered Mazda MX-5 Miata ND models. This kit is designed to work in conjunction with seat lowering kits (approximately 50 mm) to correct the backrest geometry, ensuring optimal support and posture, especially for taller drivers. By lifting the backrest by 50 mm, this kit rebalances your seating position, allowing for a more natural and comfortable fit behind the wheel. It also provides approximately 30 mm of additional effective headroom by allowing your upper body to recline further. This corrected alignment restores the intended relationship between the seat's side supports, headrest, belt guides, and built-in speakers, which improves both comfort and safety during spirited driving or extended journeys. The complete kit includes all necessary components for a professional installation: backrest raising brackets, a padded leather-finished back support, and side carpet cushions for a factory-quality appearance. The Jass Performance Seat Backrest Raising Kit is fully reversible and driver-focused, making it an ideal solution for enthusiasts who prefer a lower seating position but still require proper back and head support. It is particularly recommended for drivers who position their seat fully rearward with a reclined backrest. For optimal results, it is advised to pair this kit with a seat lowering kit and to remove the backrest tensioners, which is a simple, reversible modification.
