Hi
I just got wheel dollies to store my car in the garage for the winter. My Question what is the best way to lift car to install the dollies. I have a floor jack and the jack that comes with car. I have to lift tires about 5.5 inches off ground to get dollie under tire. My floor jack is 3000lbs and has a min 3.5 to max 17.5 inch saddle lift. I know there are four spots on frame for lift points. I just want to see how you guys would do the job
thanks
Ron

You could do both fronts first by jacking up the whole front using the cross member as your jacking point with the floor jack and then the rear using the differential housing as your jacking point. Or, you could do each wheel separately with the Miata jack. Either way you go I would think you need to chock the wheel dollies that are in place as you move on to the others, otherwise the wheel dollies could (and probably will) move as you jack up the other points. Be careful!

I generally put the floor jack on the pinch seam just a little in front the the rear view mirrors. I have not had any problem with this denting the seam, even though it is not the reinforced area. You can fashion a block of wood, or hard rubber, to spread out the pressure a bit. This will lift the entire side of the car. Put the dollies under those two wheels and move onto the other side.
Alternatives- use the factory indicated jacking points and lift one wheel at a time, or if your floor jack is a long body you can put is under the diff in the rear, and a cross member in the front. This does not work for me with the compact race type jack as there is not enough room to swing the jack handle.
Are you needing the slide your car around in the garage?

If you get a hockey puck and cut a groove in it about 1/4 inch wide it will fit over the pinch joint on the Miata and allow you to use the floor jack with no problems.....or a piece of wood with a groove will do the same

That is what I would do

I always use the cross member and the diff when jacking the car. Just seems to work better for me. The Harbor Freight aluminum racing jack will get under the front easily, and will get under the rear even when the front is up in the air.

I went and sprayed the cross member and the true jacking surface inboard of the pinch welds in white so they're easy to spot. The only reason I'd jack on one of the sides was if I was removing a single tire.

On my 94, the front crossmember is just aft of the end of the plastic undertray. With a little careful manuevering, I can get the floor jack under the crossmember without the jack pad hitting the plastic undertray.

When I need to get the whole car on jackstands, I jack the front up first, then use the differential to lift the rear.

As someone mentioned, make sure you chock the rear wheels when lifting the front and then the dollies before lifting the rear (or vice versa).

I do this with my 90 every year using my floor jack. Years ago I found a special rubber pad jack saddle to replace the metal one that came with the jack. In the garage I use the jack on the side sills to raise the car enough on each side to put the wheel dollies under each front wheel. Then I go to the back and use the differential point to jack the entire rear of the car and then insert both rear wheel dollies. I have never had to chock the wheels and have never had a problem. The only way I would see not chocking the wheels being a problem is if the floor of your garage is on an incline.

As a side note, the rubber on my jack saddle is starting to come apart after many years of usage and the place I bought it from no longer sells them. The internet has not been much help in replacing it, although I did find one like it in the Harbor Freight catalog. It's not available in their stores; only a catalog item. Here's teh one from Harbor Freight:
