For owners of the BMW E36, upgrading the suspension is one of the most effective ways to enhance handling, ride quality, and overall driving enjoyment. Coilovers, in particular, have become a popular choice due to their versatility and performance upgrades. Whether you're cruising the streets, navigating twisty backroads, or carving through corners on the track, coilovers allow E36 enthusiasts to fine-tune their suspension to meet their specific needs. This guide will break down the benefits of coilovers, focusing on their adjustability, comfort, and performance-enhancing features, while providing practical tips for making the perfect choice coilovers E36.
What Are Coilovers?
A coilover (short for "coil spring over shock") is a complete suspension assembly that integrates a coil spring with a shock absorber in a single unit. Unlike traditional shocks or lowering springs, coilovers are designed with adjustability and performance in mind. This makes them a go-to suspension upgrade for E36 owners seeking better control, a more aggressive stance, or tailored handling for specific driving styles.
Coilovers offer a combination of ride height, damping, and sometimes camber adjustability, allowing owners to fine-tune their car’s suspension geometry. With a wide range of options available on the market, from budget-friendly kits to track-ready setups, there’s a coilover solution for every E36 enthusiast.
Adjustability: Taking Control of Your Suspension
One of the primary reasons E36 owners invest in coilovers is the level of adjustability they offer. Here are the key adjustment features available on coilovers and how they can transform your driving experience:
1. Ride Height Adjustment
Coilovers allow you to raise or lower your E36’s ride height. Whether you want a slammed street look or need ground clearance for uneven surfaces, coilovers give you the ability to control how your car sits. Lowering your ride height reduces the center of gravity, improving cornering stability and reducing body roll.
Tip: When setting ride height, aim for a balance between aesthetics and functionality. Extremely low setups can compromise suspension travel and cause bottoming out on bumpy roads.
2. Damping Adjustment
Damping controls how the shock absorber manages the compression and rebound of the spring. Many coilovers feature adjustable damping settings, often with multiple clicks to tune how stiff or soft the ride feels. This allows you to:
- Stiffen the setup for spirited driving or track sessions, reducing body roll.
- Soften the damping for daily comfort or cruising long distances.
Tip: Most adjustable coilovers have combined compression and rebound damping settings, but premium options may allow you to adjust each independently.
3. Camber Adjustment
Some coilovers include integrated camber plates, making it possible to adjust the angle of the wheels in relation to the road. Negative camber, commonly used in aggressive driving or motorsports like drifting, improves cornering grip by increasing tire contact during sharp turns.
Pro Tip: If your coilovers don’t have camber plates, consider adding aftermarket camber arms for greater flexibility.
4. Spring Preload
Certain coilovers also allow you to adjust the preload on the springs. This impacts how much force is required to compress the spring, influencing suspension stiffness and initial responsiveness. While increasing preload tightens up the suspension, lowering it improves road compliance.
The ability to adjust these components means you can tailor your suspension setup to suit your driving preferences and conditions, from daily commutes to weekend track days.
Comfort vs. Performance
When it comes to coilovers, one of the biggest concerns is finding the balance between ride comfort and performance. Here’s how coilovers impact both:
Comfort
Contrary to the belief that coilovers are purely for performance and create a rough ride, modern coilovers often include features that improve comfort. Damping adjustability allows you to soften the suspension for daily use, making your E36 much more enjoyable on streets and highways. Some higher-end coilover kits even come with dual-rate springs, allowing for a soft initial travel and a firmer feel under load.
However, it’s important to note that cheap or improperly tuned coilovers can make your ride overly harsh. If comfort is a priority, look for coilovers designed for street use rather than track-focused setups, as these tend to have more forgiving spring rates and damping.
Performance
Performance coilovers excel in controlling body roll, weight transfer, and cornering grip. For drivers who enjoy aggressive driving, track days, or autocross events, coilovers offer unparalleled control. Features such as adjustable damping and camber settings allow you to tighten up the suspension for razor-sharp handling. Additionally, coilovers can improve your car’s steering response and reduce understeer, making the E36 more predictable and confidence-inspiring in demanding situations.
If you're a track enthusiast, coilovers with stiffer spring rates or separate rebound and compression adjustments offer even more fine-tuning options to maximize grip and handling performance.
Striking a Balance
Choosing the right coilovers for your E36 depends on what you value most. A street-focused setup can offer a smooth, comfortable ride while still delivering a sporty feel, while performance-focused coilovers are better suited for those who prioritize handling precision over comfort.
Choosing the Right Coilovers
With so many coilover options available, it can be challenging to decide which is right for you. Here are key factors to consider:
-
Driving Style
- For daily driving with the occasional spirited ride, go for coilovers that emphasize comfort and moderate adjustability.
- For track use, focus on coilovers with higher spring rates, separate damping adjustments, and robust construction.
-
Budget
- Budget-friendly coilovers such as BC Racing or D2 Racing offer impressive performance for street or light track use.
- Premium options like KW or Fortune Auto provide advanced adjustability, durability, and race-level performance for a higher price tag.
-
Adjustability Features
- Make sure the coilovers match your adjustability needs. Street users may only need ride height and damping adjustments, while competitive drivers should prioritize rebound, compression, and camber adjustability.
-
Build Quality
- Look for coilovers built from high-quality materials such as stainless steel or aluminum. Corrosion resistance and rebuildability are essential for longevity, especially in harsh conditions.
-
Spring Rates
- Check the manufacturer's recommended spring rates to ensure they match your driving goals. Softer springs are great for comfort, while stiffer springs enhance performance.
-
Brand Reputation
- Established brands with decades of experience, such as KW Suspension or Tein, often deliver more reliable and proven performance than unknown brands.
Upgrading your BMW E36 with coilovers isn’t just about improving aesthetics — it’s about creating a suspension setup tailored to your unique driving style and goals. By understanding the benefits of adjustability, balancing comfort with performance, and choosing a quality product, you’ll transform your E36 into a car that inspires confidence whether you’re on the highway or the racetrack.
