Jass Performance is happy to offer another beautiful solution allowing tall drivers to enjoy the MX5 ND/Fiat Spider Roadster as daily driver or track with helmet underneath a rollbar. Actually, it is incredible, because you will struggle to feel this potential of hearly 60mm underneath the seat base with your hand!
Compared to the already existing Jass Performance fixed lowering adapters, the new Jass Performance seat lowering rails are:
Each of the above features is unique and their combination - incredible, because:
As mentioned the Jass Performance Lowering Rails offer two very low seating positions - they are explained below. The higher one is at -48mm and -58mm to the OEM seating position. You can alternate between both. The rails can be sent preset in one position for you with your order, default is -48mm (1.89") which is more universal and offer full travel.
The height positions compared (you will receive both options):
The installation is intuitive and easy the seat installation in the car is as easy are installing/removing OEM seat. Everything needed for the installation is included. Sold as full kit per side (seat). You need two for both seats.
Please note - the version is currently available only for standard and Fiat Spider seats, Recaro version will follow up soon.
Last but not least - should you really need them as tall driver, it makes enormous difference to combine them with the seat back rising kit.
From a tall driver (197cm or 6'6") to fellow tall drivers - it took me 9 intense months to optimise this design and make sure not a fraction of the millimeter is further possible as drop. I gained a lot of experience with the possible room/comfort/ergonomy creating mods, which I am happy to share in short below. I will be updating the list regularly.
Sum-up of the Seat Lowering Potential in a Mazda Miata ND
Please get in touch if you have further and specific questions. I will be happy to share experience and detailed knowledge about the idea and implementation.
