For car enthusiasts and performance drivers, fine-tuning your vehicle's suspension can make a significant difference on the road and track. The Subaru BRZ, known for its agility and sporty design, benefits greatly from the installation of camber plates. These components allow for precise adjustments to the camber angle, optimizing tire contact and handling characteristics, especially in demanding driving environments like Nashville’s winding roads and racing circuits. Whether you're carving through the hills of Percy Warner Park or chasing lap times at Nashville Superspeedway, dialing in your camber can transform how your BRZ behaves.

Understanding Camber Plates: The Core of Suspension Tuning

Camber plates are adjustable mounts that replace the stock strut top mounts in your Subaru BRZ. They enable you to modify the camber angle — the tilt of the wheels relative to the vertical axis when viewed from the front of the car. Proper camber adjustment improves cornering grip, reduces tire wear, and enhances overall vehicle stability. Unlike fixed factory mounts, camber plates allow for a range of adjustment, typically from -0.5° to -3.5° of negative camber or more, depending on the design.

To understand why camber matters, it helps to look at the tire contact patch. When a car corners, the body rolls, causing the outside tire to lean into the turn. Without negative camber, the tire’s face lifts off the pavement, drastically reducing grip. Adding negative camber tilts the top of the tire inward, keeping the contact patch flat against the road even under cornering loads. This translates into more traction, better steering feel, and faster lap times.

How Camber Plates Differ from Stock Mounts

The Subaru BRZ comes from the factory with fixed, non-adjustable top mounts. They use a rubber bushing that provides vibration damping but introduces flex under hard cornering. Camber plates replace these with either pillow-ball bearings or polyurethane bushings, offering both adjustability and improved steering precision. The bearing-style plates (often called “pillow-ball” mounts) allow near-zero deflection for the most direct feedback, while bushing-style plates retain some compliance for daily driving comfort.

Types of Camber Plates

  • Fixed-adjustment plates: These provide a single camber setting (often around -1.5°) and are less expensive. They suit drivers who want a simple upgrade without frequent adjustments.
  • Dual-adjustment plates: Allow independent adjustment of camber and caster on each strut. Caster influences steering stability and straight-line tracking. For aggressive track use, caster adjustment can further improve dynamic camber gain during turns.
  • Race or full-race plates: Typically feature spherical bearings with zero compliance, maximum adjustability, and sometimes eccentric camber slots for fine-grained control. These are ideal for competition but can transmit more road noise into the cabin.

Why Nashville Demands Advanced Camber Tuning

Nashville offers a unique mix of driving environments that challenge any suspension setup. From the rolling hills and twisting roads of the Natchez Trace Parkway to the technical sections of the racetrack at Nashville Superspeedway, a one-size-fits-all alignment won’t deliver optimal performance. Here’s how camber plates help you adapt:

  • Cornering on mountain roads: Roads like the “Tail of the Dragon” (a short drive east) and local favorites such as Old Hickory Boulevard demand high lateral loads. Negative camber keeps the front tires from rolling over onto their shoulders, providing consistent grip through tight hairpins.
  • Track days: Nashville Superspeedway’s 1.33-mile concrete oval and infield road course produce sustained high-speed turns where tire temperatures and wear patterns change rapidly. Adjustable camber allows you to dial in extra negative for track use and revert to a street-friendly setting afterward.
  • Daily driving on uneven pavement: Urban potholes and construction zones can upset a suspension tuned purely for track work. With camber plates, you can run a moderate negative camber (e.g., -1.0° to -1.5°) that balances tire wear and grip without ruining ride quality.

Choosing the Right Camber Settings for Your BRZ

Setting the correct camber angle depends on your driving style and track conditions. For Nashville performance driving, a slight negative camber (where the top of the tire tilts inward) is often ideal. This setup provides better grip during aggressive cornering without sacrificing too much tire life. But what numbers should you aim for?

Street-Focused Alignment

For daily driving with occasional spirited back-road runs, target around -0.5° to -1.0° of front camber, and -0.5° to -1.5° rear (the BRZ can get rear camber from arms, but plates are front-only). This range improves turn-in response and reduces the chance of inside tire wear on the street. Pair with 0° to 0.1° total toe to keep tire wear even.

Track-Focused Alignment

For dedicated track sessions at Nashville Superspeedway or autocross events at the Tennessee State Fairgrounds, go more aggressive: -2.5° to -3.5° front camber with corresponding rear camber to maintain balance. Many competitive BRZ drivers run -3.0° front and -2.0° rear, using camber plates up front and adjustable lower control arms in the back. You can expect faster corner entry speeds and reduced understeer, but tire wear will increase on the inner edges during street driving.

Compromise Setup

If you attend three or four track days a year but drive the car daily, consider a dual-purpose alignment: -1.8° to -2.2° front camber, with rear camber set to -1.5°. This provides enough grip for moderate track work while still allowing reasonable tire life on the street. The camber plates make it easy to adjust between a “street” and “track” position if you’re willing to re-align each time – or you can use a quick-release style of plate for faster swaps.

Selecting Camber Plates for Your Subaru BRZ

When choosing camber plates, consider compatibility, adjustability range, and build quality. The BRZ (and its twin, the Toyota GR86) share the same strut design, so many plates designed for one fit the other. Popular options include:

  • SPL Parts: High-quality billet aluminum plates with spherical bearings, offering camber and caster adjustment. Known for precision and durability.
  • Vorshlag: Very popular in the motorsport community, their plates include a rubber top ring to reduce noise while maintaining a solid bearing. Offer wide camber ranges (-3.5° or more).
  • Megan Racing: More budget-friendly, with a simple eccentric slot design. Adequate for street or light track use, but adjustment range may be limited.
  • GT Radial / GT Spec: Some manufacturer-specific plates come with camber plates integrated into coilover kits; if you plan to upgrade your suspension at the same time, this can be cost-effective.

Check that the plates you choose are compatible with your strut diameter and spring perch design. Most aftermarket coilovers use a 2.5″ or 60mm spring, but factory struts require specific adapters. If you haven’t changed your suspension, look for “stock strut camber plates” – some brands offer drop-in replacements that work with OEM springs and dampers.

Installation and Adjustment: DIY vs. Professional

Installing camber plates requires some mechanical knowledge, but many enthusiasts prefer professional installation to ensure precision. The process involves removing the strut assembly, disassembling the top mount, pressing in the new bearing or bushing, and reinstalling everything. Here’s a general step-by-step outline:

  1. Remove the strut: Jack up the car, remove the wheel, and unbolt the lower strut mounting bolts and the top mount nuts (usually three located under a plastic cap in the engine bay). Carefully lower the strut assembly out of the car.
  2. Disassemble the top mount: Compress the spring with a spring compressor (strongly advised – do not attempt without proper tooling). Remove the center nut that holds the top mount to the damper rod. Replace the stock mount with the camber plate, ensuring the bearing or bushing is seated correctly.
  3. Reassemble and torque: Reinstall the top nut to manufacturer torque spec, then reattach the strut to the car. Some plates require marking or indexing the adjustment slot; others have visible degree markings.
  4. Set initial camber: For a street baseline, set the plates to roughly -1.0° – you can fine-tune later with an alignment.
  5. Reinstall wheels and test: Lower the car, bounce the suspension to settle it, then drive gently to a local alignment shop for final corner balancing and toe adjustment.

Alignment After Installation

Once the plates are installed, a professional wheel alignment is mandatory. Even if you set the plates to a rough position, the actual camber angle varies with ride height, strut inclination, and chassis tolerances. A good shop will measure current camber, caster, and toe, then adjust the plates and rear arms to achieve your target numbers. In Nashville, look for shops that specialize in performance alignments – places like All Pro Alignment or Performance Alignment Nashville (verify current availability).

DIY Alignment Tips

If you have access to a level surface, a digital camber gauge (like the Longacre or SmartCamber), and a toe gauge, you can dial in camber yourself. Remember that ride height changes affect camber; if you lower the car further later, you may need to re-adjust the plates. Document your settings so you can replicate a favorite configuration.

Maintenance and Long-Term Care

Camber plates require periodic inspection, especially if you drive in harsh conditions. Spherical bearings can wear out or develop play after 20,000-30,000 miles; listen for clunking noises from the front struts. Many manufacturers offer rebuild kits. Bushing-style plates last longer but may compress over time, reducing accuracy of the camber setting. Additionally, keep the adjustment slots clean of dirt and corrosion, and apply anti-seize to the bolts if you plan to adjust frequently.

If you track your BRZ often, check the alignment after each event. Hard cornering can knock the plates off adjustment if the locking mechanism isn’t tight. Some plates use Allen bolts that require a specific torque – use a torque wrench to ensure they don’t shift.

Common Myths and Misconceptions

“More negative camber is always better.” Not true. Excessive negative camber reduces the tire contact patch during straight-line driving, causing braking distance to increase and tire wear to become uneven. There’s a sweet spot – push too far and you’ll lose overall lap time from poor braking and straight-line stability.

“Camber plates are only for track cars.” While they’re most appreciated on track, street drivers in the Nashville area benefit from even mild camber adjustment. The ability to correct for a slight pull or to sharpen turn-in makes daily driving more engaging.

“Installation is a simple DIY job.” It can be done at home if you have experience with suspension work and proper tools (spring compressor, torque wrench, jack stands). However, incorrect installation can lead to dangerous failure of the top mount. If in doubt, pay a professional – it’s cheaper than a broken strut tower.
