I'd like to do DIY oil changes on my ZL1 so I can use better oil and have that sense of accomplishment.

I'm concerned that I won't be able to use my jack stands and jack without damaging the ground effects on the side of the ZL1.

My jack stands are similar to these...

And my jack is similar to this one...

I don't really feel comfortable using a ramp because I'm afraid I'll somehow shoot past where I needed to stop and high center my car with the ramp.

 

Why not got a length of 2X12 and make some wood ramps three layers tall?
Use a 2X2 for the end for a stop and carriage bolt the 2X2 onto the three-layer ramp.
Cut the ends at 45° and drive up onto the ramp?

 

 

Get yourself some jacking pucks, like the ones ZL1Addons sells. You can get also get very similar ones for about half the price on Amazon.

Get yourself some hockey pucks, Amazon sells them as well and use the puck between the jack plate and the lift pads. It will give you about 1 inch of clearance from the panels on the side.
