Looking to sell my set of Sparco Speeds, with sliders and mounting bases (Wedge Engineering - $110 new). They do not have a 5-point hole, but I have grommets I will include if you want to cut into the seat. They are in good condition, but could definitely use a steam cleaning and they do have some fading on the out shoulder bolsters. Also the passenger seat lost a bit of threading on one bolster (it is duct taped currently) I may deal with steam cleaning them once they are out of the car. This is a package, but will separate the mounting bases from the seas.

I am asking $500 OBO. These should fit an NA or NB Miata without an issue. Other cars will not be able to sue the mounting bases, but can use the seats with sliders (and their car's proper mounting base)
