How To Lower C4 Corvette? Steps Mentioned

After knowing the benefits, if you choose to lower your C4 Corvette, you are making a good decision. Here are the steps to follow if you are doing it on your own:

Step-1:

First, set the emergency brake after parking the car on a surface level. To make sure your car doesn’t move, place a block of wood over the jack plate. Now, you have to slide the jack from under the front of the car.

Step-2: 

Now lift the car using the jack. Place jack stands on the side frame rails to keep the car stable. Remove the wheels and tire while disconnecting the sway bar.

Step-4:

At this point, you have to place the jack under your car’s lower control arm parallel to the front leaf spring. Keep on raising the jack until the shock absorber starts moving. After that, use a socket wrench to remove the shock bolts from the car.

Step-5:

Find the lower ball joint in the steering part and take out the small pin below the nut using narrow pliers. Remove the nut and use a tool to pull out the ball joint and the connection to the steering rod. Move the knuckle part aside and keep it steady with some pieces of wood.

Step-6:

Now you have to lower the jack. This will reduce the pressure from the spring. Then, repeat the 2nd, 3rd, and 4th steps on the other side. Once it’s done, you need to cautiously remove the spring.

Step-7

Once you have removed the spring, find two rubber bumpers and pivots on the spring. Then cut them using a knife without damaging the composite spring. Then use some weatherstrip adhesive on the flat side of the new spring wedges.

Step-8:

Now attach the new spring wedges in the same place as the old ones and place a piece of masking tape over them to dry them off. Then reattach all the suspension parts and reinstall the components like wheels and tires.

Step-9:

After everything, you need to replace the old bolts with new bolts, and the castle nut alongside the cotter pin. Once you are done, lower the jack and redo the process on the other side. Make sure that you have secured equal measurements on both sides.

Step-10:

Once you have completed lowering the vehicle, go for a test drive. If you need to check something, do it so you don’t leave anything behind.
