The Mazda MX5 MK3 is roomier than any other of the models, but offers similar or even less space than them. The good news is that, by replacing just one bracket a potential of 2.5″ drop of the seat rail is possible.

However, the challenge to Jass Performance turned into immediate solution(s).  I am happy to offer now two versions – offering 1″ and 2.5″ effective drop. Both solutions share the following features:

  • Both options preserve the full seat travel
  • The lowering brackets are computer stress calculated for real life crash situation
  • The above allowed weight optimisation
  • Ergonomic seating position considered

The 1″ drop version will provide most drivers with more comfortable seating position and allow tallest drivers to be able to drive the car. It will also allow average height drivers to fit in the car with helmet. This drop will allow small drivers to be able to drive the car as well – important if you are sharing a car in the family. The installation of the 1″ drop version requires drillng a hole into the OEM seat bracket.

The 2.5″ version offers the full possible lowering potential. Not many aftermarket seats (of any at all) will go below this height on slider rails. Consider this if you are average height planning to race the car or just above 6 feet (184cm) and want to have normal overview of the instruments and road ahead. The installation involves driliing a hole (removing the OEM bracket) and cutting the rails to size.

All installation hardware is provided, as well as installation manual.

Sold as full kit per side (seat). This leaves the freedom to lower both seats with different height or just swap, when needed.

Please note, both versions are available at the moment only for the pre-facelift NC (MK3) modes – the ones with the non-height adjustable seat. Version for the later models should follow later this year.
