This is one way you can do it, but you may need to have the car realigned after.

Lowered mine over the weekend, on stock bolts. It was much easier than I thought. Only drove about 40 miles since, so not sure it's fully settled yet. It dropped about 5/8" to 3/4" so far. I *might* see upwards of another 1/4" if I'm lucky.

Remember, If your gonna do this fill your tank and eat a full meal ....then have a loved one take a picture after a few miles of settling so you can tell if you have gone too far

Do not just lower the rear without an equivalent lowering of the front, if you want to go fast. At about 135 MPH the front get very light at stock height, if the rake (front to rear ride height) goes to even, it is even less and of the front height is higher than the rear, then you will have little or no ability to steer at that speed. Easy way to measure rake is at the tie down points--back of the rear point and front of the forward tie down point. With the rear point being 6 mm higher is a good place.

According to GM tech, when adjusting or lowering ride height, the front of the car should be between 1/2" to 3/4" lower than the rear for correct aero at highway speeds and above. Also affects steering and cooling.
