Top E36 Coilovers: Performance Upgrades for Enthusiast Drivers

Understanding E36 Coilovers

The E36 coilovers have garnered significant attention among automotive enthusiasts, especially those driving the BMW E36 series. Known for their performance enhancement capabilities, coilovers can transform the driving dynamics of your vehicle, making them essential for both daily drivers and track racers. But what exactly are coilovers, and why should you consider upgrading your suspension system? Let’s delve into the details.

What Are Coilovers and Their Benefits?

Coilovers are a type of suspension system that combines a shock absorber and a coil spring into a single unit. They offer adjustable settings that allow drivers to modify the ride height, dampening, and overall performance of their vehicle. The benefits of coilovers include:

• Adjustability: The primary selling point of coilovers is their adjustability. Drivers can lower or raise the height of their car for improved aesthetics or enhanced performance.
• Improved Handling: Coilovers typically feature stiffer springs than factory suspension systems, leading to better handling while cornering and less body roll.
• Customization: Many coilover kits come with adjustable damping settings, allowing drivers to fine-tune their suspension based on personal preference or driving conditions.
• Enhanced Performance: For racing enthusiasts, coilovers can significantly improve track performance by maintaining consistent tire contact with the road surface.

How E36 Coilovers Improve Handling

The BMW E36 series, produced from 1990 to 1999, was known for its well-balanced handling characteristics. However, many drivers find that upgrading to coilovers can push this performance even further. Here are several ways that E36 coilovers enhance handling:

• Stiffness: Coilovers generally provide a stiffer ride compared to stock springs, which helps maintain tire contact during aggressive cornering.
• Camber Adjustment: Many coilover systems allow for camber adjustments, improving tire grip and stability during sharp turns.
• Lower Center of Gravity: By lowering the ride height, coilovers help reduce the car’s center of gravity, resulting in improved stability and handling.

Choosing the Right Coilovers for Your BMW E36

Selecting the right coilovers for your E36 depends on multiple factors, including driving style, usage (daily driving vs. track), and budget. Factors to consider include:

• Driving Style: If you’re primarily using your E36 for daily driving, consider a coilover that offers a balance of comfort and performance. For those focused on track performance, a more aggressive setup may be necessary.
• Road Conditions: The nature of the roads you frequently drive will also play a role in your decision. If you navigate rough roads, a system that can absorb bumps effectively will be crucial.
• Budget: Coilover prices can range dramatically, so determine how much you’re willing to invest for the performance benefits gained.

Types of E36 Coilovers Available

Budget Coilovers Vs. Premium Options

When considering coilovers for your E36, you will encounter both budget-friendly and premium options. Budget coilovers are generally made with less expensive materials and components, which can lead to sacrifices in durability and performance. Premium coilovers offer high-quality construction, extensive adjustability, and better overall performance. Some examples include:

• Budget Options: Brands like Raceland and BC Racing provide cost-effective coilover systems suitable for casual drivers who seek better ride quality without breaking the bank.
• Premium Options: Brands like KW and Bilstein provide high-performance coilover systems that excel in adjustability and durability, catering to serious enthusiasts.

Adjustable vs. Non-Adjustable E36 Coilovers

One of the major distinctions among E36 coilovers is whether they are adjustable or non-adjustable. Non-adjustable coilovers are typically easier to install and may work well for drivers who prefer a straightforward solution without needing to tweak settings. Conversely, adjustable coilovers offer the benefit of customizing ride height and damping settings, making them ideal for those who want to get the most out of their suspension system.

Coilovers for Daily Driving and Track Use

Understanding how you intend to use your E36 will help guide your decision in selecting coilovers. Coilovers designed for daily driving prioritize comfort, while those intended for track use are engineered for performance. Many manufacturers now produce hybrid models that provide balance for both use cases, recognizing that many drivers enjoy spirited weekend drives as well. For example:

• Daily Driving: Look for coilovers with a softer spring rate and adjustable damping settings, which can provide a comfortable ride while still improving handling.
• Track Use: Opt for a stiffer setup that allows for precise adjustments, such as those offered by the BC Racing BR Series or KW V3 systems.

Installation Guide for E36 Coilovers

Tools and Equipment Needed

Transforming your E36’s suspension is a rewarding yet complex task. Below is a list of tools you will need for a successful coilover installation:

• Wrenches and Sockets: Various sizes to fit the suspension components.
• Jack and Jack Stands: To safely lift the vehicle.
• Screwdrivers: Flathead and Phillips head for removing parts.
• Strut Spring Compressors: To handle the coil springs safely.
• Torque Wrench: To ensure proper torque settings are adhered to.
• Alignment Tools: To confirm proper alignment post-installation.

Step-by-Step Installation Process

Installing coilovers in your E36 can be a detailed process. Follow these steps for a proper installation:

1. Preparation: Start by parking your E36 on a flat, level surface and gather your tools.
2. Lift the Vehicle: Use a jack to lift the car and secure it with jack stands.
3. Remove Wheels: Take off the wheels to access the suspension components.
4. Remove Old Struts: Detach the old struts and springs using appropriate tools.
5. Compress Old Springs: Use spring compressors on the old springs if they will be reused.
6. Install Coilovers: Position the new coilovers in place, tightening all components according to the torque specifications.
7. Adjust Height and Damping: Initial adjustments can be made according to your preference; you might want to adjust them later after road testing.
8. Reinstall Wheels and Lower Vehicle: Reattach the wheels, lower the car, and remove the jack stands.
9. Alignment: It’s recommended to have a professional alignment done to ensure the best handling and tire longevity.

Common Mistakes to Avoid

While installing E36 coilovers, there are pitfalls you may encounter. Some common mistakes to refrain from include:

• Improper Torque Settings: Not ensuring the correct torque can lead to failure in suspension components.
• Inadequate Preload: Failing to adjust the spring preload correctly may impair handling and comfort.
• Neglecting Alignment: Skipping the alignment process after installation can affect performance and wear on tires.

Tuning Your E36 Coilovers for Optimal Performance

Understanding Damping and Spring Rates

Two critical factors to grasp when tuning your coilovers are damping and spring rates. Damping refers to how quickly the shock absorbers react to compression and rebound, while spring rates determine how stiff or soft the coil springs are. Understanding these two concepts allows drivers to achieve the desired balance between comfort and performance.

How to Adjust Coilovers for Different Driving Conditions

Depending on your driving needs, you may want to adjust your coilovers dynamically. For example:

• Daily Comfort: Consider a softer damping setting to promote comfort during daily commutes.
• Track Performance: A stiffer setting may be best to maximize grip and feedback when on the track.

Tips for Regular Maintenance of E36 Coilovers

To ensure your E36 coilovers maintain their performance over time, regular maintenance is essential. Here are some best practices:

• Clean the Coilovers: Keep them clean and free from dirt and debris to prevent corrosion.
• Check for Leaks: Inspect for any signs of oil leaks around shock absorbers regularly.
• Recheck Settings: Periodically check your height and damping settings, especially after rough driving conditions.
