B-G Racing Aluminium Camber Gauge Frame (BGR307)

B-G Racing Aluminium Camber Gauge Frame (BGR307) — a professional race-car wheel alignment tool for measuring camber and, when used with the appropriate turn or slip plates, castor. Choose the frame on its own or the complete option with the B-G Racing Digital Dual Axis Angle Gauge (BGR304). The CNC-machined aluminium frame suits wheel rim sizes up to 20 inches and is designed for repeatable setup work on race cars and performance vehicles.

Why Accurate Camber Measurement Matters

Camber affects tyre contact, cornering grip, braking stability, tyre wear, and overall vehicle balance. Repeatable camber measurements help race teams return to a known setup after a suspension change, tyre change, kerb strike, or trackside adjustment.

For a complete alignment workflow, camber measurement is normally considered alongside ride height, castor, toe, corner weights, and the condition of the setup surface. This gauge is a measurement tool, so the accuracy of the result also depends on consistent vehicle preparation and correct use.

Key Features

• CNC-machined aluminium frame — durable and suitable for workshop or trackside setup work
• Digital Dual Axis Angle Gauge option — adds digital camber and angle readings through the BGR304 gauge
• Fits wheel rims up to 20 inches — suitable for many race cars and performance vehicles
• Removable digital gauge — select the complete option or use the frame with a compatible gauge setup
• Left- and right-handed use — practical for different workshop and vehicle positions
• Castor measurement capability — use with suitable turn plates or EZ Sweep Castor Slip Wheel Alignment Plates

Choose The Right Option

Without Digital Dual Axis Angle Gauge: choose this option if you already have a compatible angle gauge or want the B-G Racing aluminium camber frame on its own.

With Digital Dual Axis Angle Gauge: choose this option if you want the B-G Racing BGR304 digital gauge supplied with the BGR307 frame. The gauge reads angle across a -90° to +90° range in 0.02° increments.

Typical Motorsport Applications

• Circuit and club racing
• Endurance and GT race cars
• Touring cars
• Rally cars
• Drift and time-attack cars
• Track-day and performance vehicles

Using The Gauge In A Repeatable Setup

Prepare the vehicle consistently, confirm the wheel and suspension are settled, and use the same measurement process each time you record a setup. The frame should be seated correctly against the wheel, with the vehicle position and surface kept consistent between measurements.

For castor work, use suitable turn plates or slip plates and follow the relevant equipment instructions. Record the result with the vehicle setup notes so you can compare changes between sessions. If you are unsure about the measurement method or wheel fitment, contact us before ordering.

Frequently Asked Questions

Does the digital gauge come included?
Only with the With Digital Dual Axis Angle Gauge option. The Without Digital Dual Axis Angle Gauge option includes the aluminium camber frame without the BGR304 digital gauge.

Can this gauge measure castor as well as camber?
Yes, the frame can be used for castor measurement when combined with suitable turn plates or B-G Racing EZ Sweep Castor Slip Wheel Alignment Plates (BGR302).

What wheel sizes does it fit?
The frame is designed for wheel rim sizes up to 20 inches. Confirm the wheel, frame contact points, and available clearance for your specific application.

Can I use this with hub stands?
The digital gauge is removable and the frame is designed to work with compatible B-G Racing hub-stand mounting equipment. Check the relevant hub-stand and mounting-kit fitment before ordering.

Is this suitable for road cars as well as race cars?
It can be useful for performance and track-day vehicles, but the measurement method, wheel fitment, and vehicle preparation still need to be suitable for the specific car.

Is this available in New Zealand and Australia?
Yes. Harris Race Radios is the B-G Racing supplier with NZ stock and shipping available to Australia, with stock available for fast dispatch to customers across New Zealand and Australia.
