A C6 Corvette is one of the prized vehicles in Chevrolet’s lineup of Corvette sports cars. Featuring an aesthetically appealing design and a powerful engine with excellent handling, the C6 is a truly outstanding machine and vehicle. If you have one of these cars and you wish to help set it apart from other Corvettes on the road, one of the best ways to do this is through custom modifications to the body or design. While these procedures can be very expensive in many cases, one that is not quite as costly is the lowering process. Lower your C6 with a custom suspension springs kit that you can install at home for less money than at a custom shop.
Step 1 — Gather the Necessary Materials
You’ll need the following materials and tools in order to lower your C6 Corvette:
Hydraulic jack with adjustable tall jack stands (two)
Socket wrench with different size sockets
Assistant to help with the procedure
Step 2 — Prepare the Car
First, park the C6 Corvette in a flat and open space where you’ll have plenty of room to work. Make sure that the emergency break is set if the car has a manual transmission, and that the vehicle is in park if it’s an automatic. Raise up the front end of the vehicle first using the hydraulic jack, then mount it on the jack stands so that the stands are on the outer section of the chassis and so that you’ll have room to work underneath the vehicle.
Step 3 — Remove the Front Springs
Loosen the lug nuts with the socket and torque wrenches so that you’ll better be able to access the springs which are located behind the wheels of the car. Before you remove the passenger’s side spring first, turn the steering wheel in the car all the way to the left side to help facilitate. Later, when you remove the driver’s side spring, move the steering wheel all the way to the right. To remove the spring, cut the caliper bolt with the breaker bar so that you can move it out of the way. Be very careful as you work with the spring, as it is compressed and can cause a great deal of damage and injury if dealt with improperly. Decompress the spring with the help of your assistant so that you can remove it. Repeat the process on the other side of the car.
Step 4 — Replace the Front Springs
Move the caliper out of the way and hold open the A-Arm so that you can replace the first front spring. Fit it into the top isolator and close up the system, being sure that it’s secured in place when you do. You can use either of the front springs on either side of the car, as they’re fully interchangeable.
Step 5 — Remove and Replace the Rear Springs
Next, lower the vehicle from the mounts and then jack up the rear portion of the car so that you’ll have room to work underneath it once again as well. Generally, repeat the same process of removing and replacing the springs. Look for the bottom isolator for the rear springs instead of the top isolator. The rear springs are not as delicate and dangerous as the front, but they can still cause damage. Also, the rear springs are not interchangeable, so it’s important that you put them in the correct position on the car system.
Before you lower the car once again, tighten up the lug nuts and ensure that all of the different systems are set back into place. Then remove the vehicle from the jack stands and evaluate the positioning of the car before you drive it.
If you have any other questions or concerns about the procedure for outfitting your C6 Corvette with a new set of suspension springs to help lower it, speak with a professional in your area. Custom body specialists, Corvette dealers and other authorities can all help you to ensure that you complete the procedure correctly.
