Ride Height & Rake Calculator
The BuildLockr ride height rake calculator helps tuners perfect their chassis stance. Use this tool to calculate your vehicle's exact rake percentage using front height, rear height, and wheelbase. Whether you are dialing in a track car for better aerodynamic downforce or setting up a drag car for weight transfer, this suspension geometry calculator handles the math. This helps builders achieve their target handling characteristics and visual stance with precision.
How to Calculate Rake Angle
R% = (Rh - Fh) ÷ Wb × 100
Ride height and rake angle are fundamental suspension geometry settings that affect aerodynamics, handling balance, and weight transfer characteristics. Positive rake means the rear of the vehicle is higher than the front.

Typical Rake Settings
- Street Cars: 0.5% - 1.5% positive rake.
- Track/Road Course: 1.0% - 2.5% positive rake (helps with turn-in and aerodynamic nose-down stability).
- Drag Racing: 2.0% - 4.0% positive rake (to pre-load weight transfer to the rear tires).
- Drift Setups: Often run lower (0.0% - 1.0%) to maximize overall contact patch and predictability.
Common Ride Height Questions
What is chassis rake?
Chassis rake is the difference in ride height between the front and rear of a vehicle. Positive rake means the rear is higher than the front, which heavily impacts aerodynamics and handling balance.
How do you calculate rake percentage?
To calculate rake percentage, subtract the front ride height from the rear ride height, divide that difference by the vehicle's wheelbase, and then multiply by 100.
Why is positive rake used in track cars?
Positive rake creates a nose-down attitude that improves front aerodynamic downforce and helps reduce underbody drag. It also physically shifts the center of gravity slightly forward, which can sharpen turn-in response.
