Thrust angle sounds like one of those alignment terms you need a degree to understand. But the idea behind it is actually very simple.
Thrust angle is just the direction a car is being pushed from the rear.
That’s it. No math required.
Before we talk about real cars, it helps to imagine something much simpler.
Imagine a toy car on the floor.
If you push it straight from the back, it goes straight.
But if you push it slightly from one side, the car doesn’t go straight anymore. It moves forward, but also a little sideways.
The direction the car travels depends on where the push is coming from.
That direction is thrust angle.
On a real car, the rear wheels are doing the pushing.
If the rear wheels are perfectly aligned with the body, the car is pushed straight down the road.
If the rear wheels are angled even slightly, the car is pushed slightly sideways as it moves forward.
The angle might be small, but the push never turns off. It’s there every second the car is moving.
When the rear of the car is pushing slightly off-center, the front wheels have to compensate.
That’s why the steering wheel ends up a little crooked, or why you keep making tiny corrections on the highway, even if the front wheel alignment is perfect.
The front isn’t broken. It’s just reacting to the direction the rear is pushing the car.
Thrust angle is not about how the car looks on a rack. It’s about the direction the rear of the car wants to travel.
This is also why different tools talk about thrust angle in different ways.
With Gyraline G1, you can see thrust angle as a visual offset. You’re looking at which direction the car wants to go.
With Gyraline G2, you can also measure it as a number. Same idea, just expressed more precisely.
Once you understand the direction first, the numbers make a lot more sense.
