If you don't have Race Ramps for oil changes, you should get them. I have the 56" with extenders. Very gentle angle of attack. Makes it easy to "get it up!"
You are right about that. I thought about having the front end raised an inch but decided against it. You have to watch out when parking in lots with the concrete parking blocks. The chin splitter will hit them all if you forget to be careful. This is a car that truly needs front parking sensors. My Wife's BMW has them and they work really great.
Yeah. I'll have to take measurements at various heights.....never got time before it got nasty out here.
