If you’re considering upgrading your BMW E36 with coilovers, it’s likely because you want to improve your car’s handling, performance, and overall driving experience. Coilovers are among the most versatile suspension upgrades, offering a wide range of adjustability to help you fine-tune your ride for various conditions. However, purchasing the right set can be overwhelming, especially with so many options available. This guide will walk you through the essential factors to consider before making your decision coilovers for E36.
What Are Coilovers?
Coilovers, short for "coil springs over shocks," are a suspension system that integrates a coil spring and shock absorber into a single unit. Unlike traditional suspension setups with separate springs and shocks, coilovers allow for more precise adjustments to ride height, damping, and occasionally spring stiffness. They’re an excellent upgrade for BMW E36 models, particularly for enthusiasts looking to improve performance on the track or simply enjoy more engaging handling on the road.
Types of Coilovers
- Non-Adjustable Coilovers: These are pre-set by the manufacturer for a specific balance of performance and comfort. They’re simple and budget-friendly but lack customization.
- Height-Adjustable Coilovers: Allow you to change the car’s ride height, which is useful for aesthetics or minimizing body roll.
- Fully Adjustable Coilovers: Offer comprehensive settings for ride height, damping, and sometimes camber. These are ideal for track enthusiasts who need fine-tuning capabilities.
Key Features to Consider When Buying Coilovers
Not all coilovers are created equal. When shopping for the right set for your E36, here are the key features to evaluate:
1. Build Quality
Durability is critical, especially if you frequently drive on challenging roads or take your car to the track. Look for coilovers made from corrosion-resistant materials like stainless steel or aluminum. High-quality seals and coatings also make a difference in long-term performance.
2. Adjustability
The level of adjustability matters based on your driving needs:
- Ride Height: Lowering the car improves stability and reduces weight transfer during hard cornering.
- Damping (Rebound/Compression): Adjustable damping lets you control how quickly the suspension responds to bumps or maintains tire contact.
- Spring Preload: On some models, you can adjust the tension on the spring to tailor handling.
3. Spring Rates
Spring rate refers to the stiffness of the spring. Stiffer spring rates provide sharper handling, which is great for track use, but they may also result in a harsher ride. Consider your primary use—track, street, or both—when choosing spring rates.
4. Camber Plates
Camber plates allow adjustments to camber angle, which can improve tire contact during cornering. Many performance coilovers include camber plates, especially those designed for track use.
5. Monotube vs. Twin-Tube Design
- Monotube Shocks: Provide more consistent damping and performance. Ideal for track-focused setups.
- Twin-Tube Shocks: Offer a smoother ride and are often better suited for daily driving.
6. Budget
Coilovers can range from affordable street-oriented kits to high-end track-focused systems. Decide on your budget before narrowing down options.
Benefits of Upgrading to Coilovers
Upgrading your E36 suspension to coilovers offers several advantages. Here are the most significant benefits:
Enhanced Handling
Coilovers minimize body roll, improve traction, and allow for sharper, more predictable steering. These features make them essential for track days and spirited driving.
Adjustable Ride Height
Lowering your E36 improves aerodynamics and center of gravity. Coilovers give you the flexibility to dial in the ideal ride height for both performance and aesthetics.
Custom Tuning
Whether you’re driving on the street or tackling the track, coilovers allow you to tailor your suspension setup to your preferences. Adjust damping, spring stiffness, and height depending on the environment.
