For car enthusiasts and racers in Nashville, the off-season isn’t just about parking the car—it’s about safeguarding high-performance suspension components like camber plates. These precision parts allow you to dial in negative camber for better cornering grip, but they’re vulnerable to moisture, temperature swings, and contamination during months of inactivity. Nashville’s unique climate—humid summers, mild but damp winters, and frequent temperature oscillations—presents specific challenges. Proper storage ensures that when spring arrives, your camber plates are ready to deliver consistent alignment and handling, not rust pitting or seized bearings.
This guide covers everything from cleaning techniques to long-term environmental controls, helping you preserve both the adjustability and longevity of your camber plates. Whether you run a daily driver with occasional track days or a dedicated race car, following these steps will save you time, money, and the frustration of replacing components prematurely.
Understanding Camber Plates and Their Role
Camber plates are the link between your vehicle’s strut top and the chassis, providing an adjustable mounting point for the suspension upright. They allow you to change the camber angle—the tilt of the tire relative to vertical—without swapping out control arms or modifying the strut tower. Most aftermarket plates use either spherical bearings (rod ends) or urethane/elastomer bushings at the pivot point.
Spherical-bearing plates offer the widest adjustment range and zero deflection, making them the choice for track-focused builds. However, they require more careful maintenance because the bearing itself can corrode or lose its smooth action if moisture intrudes. Bushing-based plates are more tolerant of road grime and have longer service intervals, but they can add compliance that some drivers prefer to avoid.
Regardless of type, camber plates are exposed to the same elements: rain, road salt, brake dust, and underhood heat. In Nashville’s off-season—roughly November through March—these parts sit for extended periods. Without proper storage, the spherical bearing can seize, the bushing can crack from UV exposure, or the aluminum body can oxidize, making future adjustment frustrating or impossible.
Understanding the specific materials in your camber plates is the first step. Common construction includes CNC-machined 6061-T6 aluminum, steel hardware, and either a chromium-plated or bronze-steel bearing race. Each material reacts differently to humidity and temperature; steel fasteners rust quickly, while aluminum can pit if not coated adequately.
Why Nashville’s Climate Demands Special Care
Nashville sits in a humid subtropical zone (Köppen Cfa) with average relative humidity between 60% and 80% year-round, frequently spiking over 90% during rain events. The off-season brings cool, damp air with temperatures ranging from the low 20s°F to the mid 50s°F. These cycles of cold and mild weather, combined with high humidity, create condensation inside garages and unheated storage spaces. When a warm front moves in after a cold snap, moisture condenses on metal surfaces—including your stored camber plates—accelerating corrosion.
Moreover, Nashville sees about 120 days of measurable precipitation annually, and many garages lack tight seals or climate control. Even if your car is in a storage unit, temperature fluctuations cause air to expand and contract, drawing in moist air. For camber plates, the risk is twofold: the bearing or bushing can trap water, and the aluminum body can develop white powdery corrosion (aluminum oxide) that interferes with the sliding adjustment mechanism.
Another factor is road salt carried over from winter driving. If you drove your car briefly before storing it, salt residue can cling to hard-to-reach crevices. Salt is hygroscopic, meaning it attracts moisture, creating a localized corrosive microenvironment. Proper storage begins before the car is parked for good—you must thoroughly clean and neutralize any salt contamination.
For data on Nashville’s average temperature and humidity patterns, the National Weather Service provides detailed climate records [1]. Additionally, the American Society for Testing and Materials (ASTM) has standards for accelerated corrosion testing that relate to how materials degrade under these conditions [2]. Understanding these external factors helps justify the level of care we’ll outline next.
Proper Storage Procedures
Storing camber plates correctly involves a sequence of cleaning, drying, coating, and environmental selection. Skipping any step compromises the result. Below, each stage is broken down with actionable techniques.
Thorough Cleaning Techniques
Before storage, remove the camber plates from the vehicle if possible. On most MacPherson-strut cars, this means unbolting the top nuts, lifting the strut assembly, and separating the plate from the spring perch. Work on a clean bench with proper lighting.
Start by spraying the plates with a biodegradable degreaser such as Simple Green or a dedicated brake cleaner. Use a stiff-bristle nylon brush to agitate embedded grime, paying attention to the bearing housing, adjustment slots, and any threaded fasteners. For spherical-bearing plates, avoid forcing debris into the bearing; instead, use a soft toothbrush or a pointed detailing brush. Rinse thoroughly with water—or better, with distilled water to avoid mineral deposits—then blow away standing moisture with compressed air.
If you notice caked-on grease that looks hardened, soak the plates in a solvent like mineral spirits for 10–15 minutes, then scrub again. Never use wire brushes on aluminum surfaces; they can embed steel particles that later cause galvanic corrosion. A non-metallic abrasive pad (like a Scotch-Brite) is safe for stubborn spots.
For bushings, check if the elastomer has any cracks or swelling. If it does, consider replacing the bushing before storage. A damaged bushing will degrade faster when sitting because the open cracks collect moisture.
Drying to Prevent Moisture Trapping
Drying is the most critical step—and the one most people rush. Any moisture left in the bearing race, underneath a washer, or inside a threaded hole will cause corrosion over weeks. After cleaning, use a heat gun on a low setting (around 120°F) to warm the parts evenly, especially around the bearing. Keep the gun moving to avoid overheating seals. Alternatively, place the parts in an oven at 170°F for 20–30 minutes, monitoring carefully—do not exceed the temperature rating of any polymer components (typically 200°F).
For intricate areas, follow up with a desiccant pack inside a sealed bag. Leave the parts in the bag with a silica gel pack for 24 hours to draw out residual moisture. Avoid wicking cloths or paper towels, which can leave lint inside bearing races.
If you have steel plates (common on budget kits), use a portable dehumidifier in the storage room to keep relative humidity below 50%. You can also place a moisture-indicating card (cobalt chloride strips) inside the storage container to check conditions at a glance.
Applying Protective Coatings
Once dry, apply a light oil or protectant to all metal surfaces. For spherical bearings, use a thin, low-viscosity lubricant like Tri-Flow or a Teflon-based spray that won’t attract dust. Spray a small amount into the bearing and cycle it through its range of motion to distribute the oil. Wipe away any excess that could drip onto the lubricated surfaces of the adjustment mechanism.
For aluminum bodies, a corrosion inhibitor like WD-40 Specialist Corrosion Inhibitor or Boeshield T-9 works well. These leave a waxy film that repels moisture. Avoid heavy greases that can harden over months and later attract dirt. Steel nuts and bolts should be evenly coated with a rust-preventive spray; then wrap them individually in acid-free paper or place them in a small zip-top bag.
Bushings (urethane or rubber) benefit from a silicone-based protectant like 303 Aerospace Protectant. This prevents the UV and ozone degradation that can occur even indoors if storage is near a window or under fluorescent lights. Apply a thin coat, let it soak in, then wipe off excess.
If your camber plates use anodized aluminum, the anodizing itself provides some corrosion resistance, but the edges where the coating is thin (around drilled holes) are still vulnerable. A spray-on clear coat (e.g., a stencil of Rust-Oleum Clear) can add an extra barrier for long-term storage.
Selecting the Right Storage Environment
The best protection begins with the storage location. Ideally, keep the camber plates inside your home’s conditioned space—a heated basement, a climate-controlled closet, or a temperature-stable storage unit. If that’s impossible, use a large plastic tote with a gasket seal (like a Sterilite or Husky weatherproof bin) and place it in the driest part of your garage, away from water pipes and exterior walls.
Inside the tote, line the bottom with a moisture-absorbent mat or a layer of silica gel beads. Put the camber plates in separate anti-static, anti-corrosion bags (available from industrial suppliers) or wrap them in vapor-phase corrosion inhibitor (VCI) paper. VCI paper releases a chemical that migrates to metal surfaces and forms a protective layer; it’s commonly used for shipping precision parts and works well for long-term storage.
Monitor the environment with a digital hygrometer. If humidity inside the tote exceeds 55%, replace the desiccant. Avoid attics or unconditioned sheds: Nashville’s high summer heat (90+°F) can degrade rubber bushings even during the off-season if stored incorrectly, and condensation forms on a daily basis.
Direct sunlight is another enemy. UV rays break down polymer bushings and can fade or embrittle coatings on aluminum. If the storage tote is translucent, paint the outside or cover it with a dark tarp. Better yet, use an opaque tote.
Correct Positioning to Avoid Deformation
Store camber plates flat, on their side, or hanging from the adjustment slot with a padded hook—never stack heavy items on top of them. Urethane bushings can develop a set if compressed under weight for months. If you store the plates with the spherical bearing upright, the bearing can settle, but this is only a concern if the plates are stacked horizontally under load. With no load, the bearing position is not critical.
For plates with fragile adjustment shims or slotted plates, place them in a foam-lined compartment within the tote. This prevents them from sliding around and scratching. The goal is to keep all surfaces contact-free to prevent moisture trapping between layers.
Additional Considerations for Coilover and Suspension Components
Many car owners store camber plates still attached to coilovers or strut assemblies. While convenient, this practice introduces risks. The coilover spring can apply constant force to the bearing, causing localized wear or flat spotting if the car is static. Additionally, the dampers may leak seal fluid if compressed or extended for months.
If you must store the entire assembly, release the spring tension by backing off the perches, or better, remove the spring and store it separately. Wrap the coilover body and camber plate together in plastic sheeting but leave the bearing exposed for air circulation—otherwise condensation can form inside the wrap.
For race teams prepping multiple sets of wheels and suspension, consider a dedicated parts rack in a humidity-controlled area. Label each set of camber plates with the intended vehicle and alignment settings (e.g., “-3.5° camber, driver’s side”). This makes spring reinstallation faster and avoids confusion.
Some manufacturers, such as Vorshlag and Ground Control, provide explicit storage guidelines for their camber plates [3]. Following these recommendations keeps warranty coverage intact and ensures long-term reliability.
Regular Inspection During Storage
Don’t simply seal the parts away and forget them until spring. Check the camber plates every four to six weeks for moisture intrusion or signs of corrosion. Open the tote, feel for dampness, and look for any white powder on aluminum (aluminum oxide) or orange rust on steel components.
If you notice rust, remove it immediately with a fine brass wire brush or 0000 steel wool (only on steel parts). Then reapply the protective coating. For spherical bearings, cycle the bearing through its full range of motion to ensure it hasn’t seized. If resistance increases, add a drop of lubricant.
This inspection is also an opportunity to verify that the desiccant is still active. Silica gel turns from blue to pink when saturated; recharge it by heating in an oven at 250°F for two hours. Other desiccants may have different indicators.
If you store the plates in a shared garage or storage unit, pests can be a problem. Mice or insects might nest inside the tote if it’s left partially open. Seal all openings and consider using a repellent like peppermint oil bags around the perimeter.
Preparing for Reinstallation at Season Start
When it’s time to reinstall the camber plates, perform a mini-refresh. Remove any protective coatings with a degreaser, then inspect the spherical bearing or bushing for free movement. Apply fresh grease or lubricant as specified by the manufacturer. Re-torque all fasteners to the original specifications (usually listed in foot-pounds in your vehicle’s manual or the plate’s installation guide).
Double-check the alignment marks you set before storage, but plan to have the alignment rechecked by a professional after installation. Over the storage period, the suspension bushings may have settled or the subframe might have shifted slightly. A proper alignment protects tire wear and ensures the handling characteristics you worked to achieve.
If you stored the plates with the car’s alignment settings recorded (some owners note the number of turns on each adjustment screw), save that record. It speeds up the reinstallation and provides a baseline for troubleshooting if something feels off after the first drive.
Conclusion
Properly storing camber plates during Nashville’s off-season is more than a simple “put them in a box” task. The combination of high humidity, temperature swings, and road salt residue creates an environment that can quickly degrade precision components. By following a systematic approach—thorough cleaning, meticulous drying, application of appropriate protective coatings, and storage in a climate-controlled or sealed environment—you can keep your camber plates in like-new condition for many seasons.
The upfront effort pays dividends: fewer replacement parts, consistent handling from the first spring outing, and no frustration from seized bearings or corroded hardware. Whether you’re a weekend autocrosser or a serious track-day participant, treating your suspension components with the same care you give your tires and brake pads ensures your car is ready to perform when Nashville’s roads (and tracks) call again.
