Super easy to do, I made mine about 4 years ago and they still look like new. They could support a house they are so strong and are a heck of a lot cheaper than buying "race ramps".
Just an option for you to have. If you do not like it, then do not build it.

For slammed stangs and the DIY'er
If your stang is lowered more than 2 inches, or you just find it a PITA to lift the front of your car then you might need to make yourself some MW ramps :-)
(DIY means "Do it yourself" of course)
