how to lower 03 z06




The rear end is easy. No need to jack the rear end or take the rear wheels off, but it may be easier for you to get under the car if the back is brought into the air. Here is a pic of the passenger rear. The bolt is in the middle of the picture. The nut is on top of the leaf spring and the hex head is below the leaf spring. I think the bolt is 18mm, but I dont really remember. Take a socket wrench to the hex head below the leaf spring. At the same time use an adjustable wrench to hold the nut atop the leaf spring in place so it doesnt move when you turn the bolt. Loosen the bolt counterclockwise until there are about two thread showing above the nut. Do the same for the other side.

Here is a pic of the driver side rear bolt.

Ok, now for the fronts. Jack up the front end and place it on jack stands. Take the front wheels off. In order to lower the fronts, all weight must be taken off of the front spring. You can use your floor jack and a small piece of wood as shown in the picture below. As the picture shows, it is important to get as close to the end of the leaf spring as possible to take all of the weight off. Leave the jack in place.

Next, now that the front is on jack stands and the weight of the car has been taken off of the spring, get yourself a 10mm socket (again I forget the exact size) and an adjustable wrench. The bolt is a little hard to see in the next pic, but i circled it in white. However, the front bolts are reverse threaded, so you want to turn them counterclockwise. This means, that when you are done, there will be more threads showing above the nut.
couldnt you take it to were all of them were not visual, i mean the nut is still gonna have all threads in contact inside if that makes sense, also my car only lost 1/2 inch gap from tire to fender, but it was 1/2 inch all around so it was a perfect drop, i just took it around the block, maybe it needs to settle more?? thanks for the free mod info
also, i looked at mine and there is no nut on the front adjustment bolt. is that stock or did someone mess with it. i bought the car used and it seems to be stock height but i was surprised there was no locking nut on the front adjustment.
