How to Align Your Race Car Properly (Step-by-Step Motorsport Setup Guide)
My Store AdminGuide written by Aaron Harris – Barcelona 24 Hour class winner, Bathurst competitor, and race engineer for International Motorsport, Earl Bamber Motorsport, and Matt Stone Racing.
How Professional Teams Approach Setup
Alignment isn't just about hitting numbers — it's about creating a repeatable system that allows accurate adjustments.
Professional GT race car set up using B-G Racing string line alignment system for precision motorsport alignment.
Learn how professional race engineers align race cars using B-G Racing hub stands, string alignment systems, and camber/caster tools.
Step 1 – Race Engineering Insight
Aaron Harris explains how professional race engineers approach car setup.
Before any adjustments are made, engineers define:
- Target toe settings (front and rear)
- Camber and caster values
- Steering centre position
- Tyre and track conditions
Alignment isn't about guessing numbers — it's about building a repeatable system that delivers consistent performance.
Step 2 – Install B‑G Racing Hub Stands
Hub stands remove tyre distortion and allow accurate setup work.
Tyres introduce flex, movement, and inconsistencies — especially when the car is rolled or repositioned. By removing the wheels and working directly from the hubs, you eliminate these variables entirely.
This allows:
- Direct hub‑to‑hub measurement
- Faster setup changes
- More consistent and repeatable results
Hub stands remove tyre distortion and allow accurate setup work.

Step 3 – Set Up B‑G Racing String Lines
String lines create a precise reference box around the vehicle.
The key to accurate alignment is having a true and stable reference line that runs parallel to the chassis.
Key setup principles:
- Strings must be perfectly parallel
- Equal distance from both sides of the car
- Positioned at hub centre height
- Tight and stable (no sag or movement)
If the string setup is wrong, all measurements will be incorrect.
String lines create a precise reference box around the vehicle.

Step 4 – Measure Camber & Caster (B‑G Magnetic Gauge)
B‑G Racing camber and caster gauges allow accurate measurement directly from the hub.
By measuring at the hub rather than the wheel, you eliminate tyre inconsistencies and improve measurement accuracy.
What to check:
- Left vs right camber balance
- Caster symmetry
- Suitability for track conditions
B-G Racing camber and caster gauges allow accurate measurement directly from the hub.

Step 5 – Adjust and Re‑Measure
This is where precision matters most.
Process:
- Make small adjustments only
- Measure after every change
- Keep both sides symmetrical
- Never rush the process
Most alignment problems come from adjusting too quickly and not re‑checking.
Consistency is more important than alignment speed.
Step 6 – Final Checks
Before completing setup, confirm:
- Steering wheel is centred
- All alignment values match targets
- Nothing has moved during adjustments
- Tyre pressures are correct
Why B-G Racing Equipment + Engineering Knowledge Wins
Where Motorsport Alignment Goes Wrong
From real race experience, the most common issues are:
- Measuring from tyres instead of hubs
- Incorrect string line setup
- Not re‑measuring after adjustments
- Setting alignment before centring steering
- Rushing the process
Alignment errors don't always show immediately — but they always affect performance.
Why Use B‑G Racing Equipment
B‑G Racing equipment is designed for:
- Accurate, repeatable measurements
- Fast, efficient setup adjustments
