Ride height measurement

Does anyone know the measurement of the ride height adjustment bolts from the top of the transverse spring to the top of the adjustment bolt on a c6 Z06. I lowered my car with the stock bolts and decided that it's not for me. I was told that it should be 24mm at all 4 corners. Shouldn't the front bolts be slightly taller to give the car it's proper rake?

HI there,
The only way GM measures ride height is in suspension measurements.
Now, this can be confusing, however very accurate of a measurement.
The diagrams below are for your Z height, which is the front suspension and the D height which is your rear.
Now, a simple way without using the GM special tool, is to obtain a good 3 ft level an a tape measure.
Now, using the level with one end at the lower ball joint, align it with the inner control arm pivot point/bushing.
Then, using a tape measure with the level completely straight, take your measurements as the diagram shows.
Front Z height should be about 1.61 inches or 44 mm
Rear D height should be about 4.3 inches or 109 mm.

Thanks.
