Want to lift up both wheels on one side of your Miata at once so you can put it on jackstands or quickly swap tires? We do this all the time. Slide the jack under the middle of the car for a quick lift. Too bad Mazda only reinforced the seam at the front and rear of the car!
A customer asked us if we could do anything to solve this problem, and here's our answer. Our jack adapter sits on top of a typical floor jack and straddles that fragile seam, putting the load on the structure of the car instead. It's similar to the way the stock scissor jack is shaped, but offers significantly more surface area to prevent damage. Requires only an extra 1/8" of clearance, about the same as the removable rubber pad on the jack. Powdercoated with a (new and improved!) textured coating to protect your car's paint and keep the adapter looking good for years. Some photos are of the initial prototype, showing bare metal.
Fits all Miatas and many other cars. The slot is 7/8" deep and 3/8" wide, so as long as your other car has seams less than 7/8" high this should work. May not fit all jacks - a particularly deep or very small platform on the jack could cause a problem. The adapter has a 3" base.
You must use the factory lift locations on NC and ND Miatas due to some extra plastic trim.
