My Z is stock height. No problem getting jack under side jack points. But I like to be able to jack up the front to change both sets of front brakes for the track and then do the rears the same way.

My "low profile" jack will not go under the front or rear.

So I made ramps out of 2x10s. Used circular saw to cut the angled ends. 45 degrees is the max angle you can get with a typical circular saw. Put a 2x4 across top end to prevent running off the end.

On the concrete driveway they work like a charm. But at the track I needed to rotate tires and the paddock area is grass and the car just pushed the ramps around.

I thought about something to try to make them grip better but in the end just put them in a vice and uses a handsaw to cut a narrower angle and that has worked fine.

 

Or you can drive nails through them for grip in the grass, if you drill the holes, the nails can be removed for when they're not in the ground.

 

If you want to lift the entire car this height just make the highest point as long as your car so you just continue to drive on it till your whole car is level! tadaa!! Problem solved.

EDIT: If you can figure it out to where you dont high center.... sorry to dig this one out of the grave haha.....
