Overview

The Jass Performance headlamp kit is a low-profile, left-hand drive unit designed as a direct replacement for the standard 7" headlamp on the mk1 Mazda MX-5 and Miata. This kit is Hella TUV approved and E-marked.

It features a low profile design with a maximum lift of 9cm and includes functionality for beam height adjustment, useful for MOTs and other inspections. The installation is fully reversible, though minor bracket modification may be required, with full instructions provided. A right-hand drive version is also available.
Show original supplier description
The Jass Performance Seat Lowering Brackets are engineered to enhance interior comfort for Mazda MX-5 NC models, specifically addressing headroom limitations for taller drivers. While the NC generation is roomier than previous models, it can still feel restrictive for those over 6 feet tall. These brackets provide a solution by allowing the seat to be lowered by approximately 4 cm (1.5 inches), significantly increasing available headroom and creating a more comfortable driving position. Crafted with computer-stress-calculated designs for crash safety and weight optimization, these brackets ensure structural integrity without adding unnecessary bulk. The installation process requires modifying the OEM seat rails and removing a small portion of the floor sound deadening. It is important to note that these brackets are compatible with height-adjustable seats and do not lower the seat beyond the level of non-height-adjustable seats found in early NC models. For NCFL models, if both seats require lowering, it may be necessary to order these brackets for the height-adjustable seat (typically driver's side) and a separate version for the non-height-adjustable passenger seat. The kit includes all necessary hardware and an installation manual, sold as a complete set for one side of the vehicle.
