I wanted to do some work on the Z today only to find out my floor jack couldn't touch this thing ugh.... so I got online did some research and found these ramps for a good price on amazon with free 2-day air. They make a smaller version thats 40" long, not sure if it would scrape on the ramps or not but only supports 8" wide tires. The 56" model supports up to 10" tires and they even make a 67" model if you're really slammed.
