Secondly, the spring coils are grinding against themselves and will destroy themselves over time. Using a plasma cutter or oxyacetylene torch to cut springs will destroy the temper of the metal and will make the spring too soft. You also shouldn't cut progressive springs or springs with square ends. Said another way, you shouldn't cut your springs unless they are perfectly helical. The system will become underdamped. The suspension will bounce up and down, which is bad for traction and bad for comfort.
This is true for any aggressive spring that is not paired with an appropriately aggressive shock. There are other problems with cutting springs excessively, but they are not limited to cut springs, but rather any aggressive lowering. You can have a situation where the spring reaches it's full extended position before the suspension has reached its full length of travel.
In other words, the spring now isn't long enough to push the suspension down all the way. The suspension droop is limited, and this can result in the inside wheel s lifting during cornering, or the wheels losing contact with the road over bumps, jumps and drops.
This may upset the car in unpredictable ways. Lastly, the suspension geometry can suffer if dropped too low. The instantaneous roll center can rise without the use of some sort of roll center correction measures. The first thing you need to know is that cutting a coil spring will not only lower the vehicle, but it will also stiffen the spring making the ride and handling a bit firmer. But this is a good thing because lowering a vehicle reduces the amount of suspension travel.
A stiffer spring will help reduce bottoming out. A safe place to start is by measuring how much you want to lower the vehicle. Then take her for a drive, and drive it like you stole it to get the springs well worked and seated properly. A professional mechanic often carries out the process of cutting a car's coil springs and lowering the vehicle. With a few tools, such as a coil compressor and angle grinder, you can cut the coil springs yourself. All of the tools and supplies necessary to cut coil springs are available at auto parts stores and home improvement stores.

Author Info Last Updated: August 5, Raise the car. Use a jack to raise the area of the car from which you will remove the old coil spring. Follow the instructions that come with your jack. Remove the tire. Take the hub cap off of the wheel. Unscrew the nuts and remove the tire. Remove the strut. The strut holds the coil spring and the shock absorbers over the tires, and allows for a smooth ride.
Spring cutting if you are cautious and don't go overboard is almost exactly the answer. The spring is shortened and the car sits lower and the spring becomes stiffer and resists bottoming out and reduces side roll for better handling. Yes, yes, if you want really stiff then an after market spring is needed for sure.
Spring cutting is a fine and viable low cost option for many car owners who want a little better ride handling and looks.

Thnks Because of older vehicles we have there arent too many options on the suspension for stance or aero dynamic purposes, unless of course you own a hehehe. Here is what you need to know when cutting your springs or heating them up. Cutting Coil Springs Every now and then the question comes up and customers want to know, "Can we cut coil springs to lower a vehicle? A spring with a tangential end would fall over if you tried to stand it on its end.
Square - the last coil bends back down to touch the coil below it. This style end allows the spring to stand up when placed on this end. Pigtail - the last coil of the spring is the square type but has a much smaller diameter than the coils in the body of the spring.
