No aftermarket seat rails were low enough so I made my own! These rails retain the stock sliding mechanism but mount your racing buckets as low as humanly possible. This auction includes complete, drivers and passenger side rails. The stock miata seat rails sit lower than anything currently available.
They were modified to create a flat mounting base for aftermarket seat brackets.
The OMP brackets I used would fit any sparco/momo/cobra seats etc. The OMP brackets are not included in this auction. These would also make a great base for bottom mount seats like kirkey, ultashield, etc.
The extensions that were welded to the stock brackets are made from 1/8 th inch plate, and are perfectly welded from both top and bottom. This may be a little overkill, but I don't mess around when it comes to safety. It should also be noted that in many classes of racing stock sliding seat rails, are the ONLY sliding rails that are legal for tech inspection. These allow you to keep the sliding mechanism, and also not have to modify your miata's stock floor pan when mounting racing buckets.
It took many hours of measuring and fabricating to discover that these would work and then build them. They are currently listed on ebay, and the buy it now is already gone. The buy it now was $110, but for miataturbo.net I'll end the auction early for $100 with free shipping to the continental US.
