How to Handle ST Coil Overs to Increase Their Durability?
ST coil-overs are bound to last a long time if they are handled the right way. Following are some of the ways in which you can handle your ST coil-overs well:
- Use a slightly smaller diameter of the coil-overs to increase the overall clearance. This helps prevent the possibility of interference by increasing the distance between the chassis and the spring.
- When choosing an ST coil-over for yourself, make sure you choose the rate before you choose the free length.
- Make sure that a coil bind does not take place. This happens when the coils adjacent to each other on the spring begin to stack up. This causes the spring to turn into a solid steel block which can be disastrous for the component life.
Note: This can be prevented by choosing the right spring length. If you are going for a lower spring rate, you need to choose a longer spring in order to prevent coil bind.
- Keep the spring bow to a minimum. When spring bows, it may rub on other chassis bits and suspensions. The bow effect increases with an increase in the length of the spring. To prevent this, use a barrel-shaped spring, use the right length of spring, and use a high-quality spring.
