Quick summary
- By reducing the distance between the chassis and the wheels, lowering springs can enhance cornering stability, reduce body roll, and create a more aggressive and sporty appearance.
- Lowering springs can improve tire grip by reducing the distance between the tire and the fender, allowing for a wider contact patch.
- After lowering the coil springs, it may be necessary to adjust the ride height to achieve the desired stance and performance.
Lowering coil springs is a popular modification among car enthusiasts seeking to improve their vehicle’s handling, stance, and overall aesthetic appeal. By reducing the distance between the chassis and the wheels, lowering springs can enhance cornering stability, reduce body roll, and create a more aggressive and sporty appearance. This guide will provide a comprehensive overview of how to lower coil springs, including techniques, tools, and safety considerations.
Benefits of Lowering Coil Springs
- Improved Handling: Lowering coil springs lowers the vehicle’s center of gravity, resulting in reduced body roll and increased cornering stability.
- Enhanced Appearance: Lowered springs give the vehicle a more aggressive and sporty stance, enhancing its aesthetic appeal.
- Better Ride Quality: Contrary to popular belief, lowering springs can sometimes improve ride quality by reducing the amount of suspension travel and providing a firmer and more controlled ride.
- Increased Tire Grip: Lowering springs can improve tire grip by reducing the distance between the tire and the fender, allowing for a wider contact patch.
Methods of Lowering Coil Springs
There are two primary methods of lowering coil springs:
- Spring Replacement: This involves replacing the existing coil springs with shorter or stiffer aftermarket springs.
- Coil Spring Compressor: This device is used to compress the coil spring, allowing for its removal and replacement with a shorter spring.
Tools and Materials Required
- Coil spring compressor
- Jack stands
- Socket wrench set
- Torque wrench
- Measuring tape
- Anti-seize lubricant
Safety Considerations
- Always use proper safety gear: Wear gloves and eye protection.
- Secure the vehicle: Park the vehicle on a level surface and engage the parking brake.
- Use jack stands for support: Never rely solely on a jack to support the vehicle.
- Handle the coil springs with care: Coil springs are under immense tension and can be dangerous if handled improperly.
Step-by-Step Guide to Lowering Coil Springs
1. Prepare the Vehicle:
- Jack up the vehicle and secure it on jack stands.
- Remove the wheels.
2. Measure the Stock Ride Height:
- Use a measuring tape to measure the distance from the center of the wheelbase to the ground.
- Record this measurement as the stock ride height.
3. Compress the Coil Spring:
- Position the coil spring compressor over the coil spring.
- Slowly tighten the compressor until the spring is fully compressed.
4. Remove the Stock Coil Spring:
- Once the spring is compressed, remove the bolts that hold the spring in place.
- Carefully lift the stock coil spring out of the suspension.
5. Install the Lowering Coil Spring:
- Insert the new lowering coil spring into the suspension.
- Tighten the bolts to secure the spring.
6. Release the Coil Spring Compressor:
- Slowly release the coil spring compressor to allow the spring to expand.
7. Repeat for the Other Side:
- Repeat steps 3-6 for the other side of the vehicle.
Adjusting Ride Height
After lowering the coil springs, it may be necessary to adjust the ride height to achieve the desired stance and performance. This can be done by adjusting the preload on the coil springs using the following methods:
- Coil Spring Adjusters: These devices allow for fine-tuning of the ride height by adjusting the amount of preload applied to the coil springs.
- Lowering Control Arms: These aftermarket control arms are designed to lower the vehicle’s ride height by altering the suspension geometry.
Considerations for Lowering Coil Springs
- Wheel and Tire Fitment: Lowering the vehicle may require different wheel and tire sizes to avoid rubbing or clearance issues.
- Suspension Travel: Excessive lowering can reduce suspension travel, affecting the vehicle’s ability to handle rough roads and bumps.
- Alignment: Lowering coil springs can affect the vehicle’s alignment, which should be checked and adjusted accordingly.
- Warranty: Lowering coil springs may void the vehicle’s suspension warranty.
Wrapping Up: The Art of Lowering Coil Springs
Lowering coil springs is a rewarding modification that can enhance a vehicle’s handling, appearance, and overall driving experience. By following the steps outlined in this guide and observing the necessary safety precautions, car enthusiasts can achieve the desired lowered stance and performance improvements. Remember to consider the factors discussed in this article and consult with automotive professionals if necessary to ensure a successful and satisfactory outcome.
What People Want to Know
1. How much will lowering coil springs affect my ride quality?
The effect on ride quality varies depending on the spring rates and the amount of lowering. Generally, lowering springs can improve ride quality by reducing body roll and providing a firmer and more controlled ride. However, excessive lowering can compromise ride comfort.
2. Will lowering coil springs affect my alignment?
Yes, lowering coil springs can affect the vehicle’s alignment. The lowered ride height can alter the suspension geometry, leading to changes in camber, toe, and caster. It is recommended to get an alignment after lowering the coil springs.
3. Can I lower coil springs without replacing the struts?
Yes, it is possible to lower coil springs without replacing the struts. However, it is important to ensure that the struts are in good condition and can handle the reduced suspension travel. If the struts are worn or damaged, it is advisable to replace them along with the coil springs.
