Modern suspension tuning is no longer guesswork or tribal knowledge passed down through forums. The GripDial's calculator ecosystem was built to bridge the gap between theory and reality, turning complex vehicle dynamics into clear visual tools that anyone can use.
Whether you are aligning a drift car, dialing in a road race setup, engineering a suspension from scratch, or refining a sim racing rig, GripDial's tools exist to answer one simple question. What is the car actually doing?
Foundational Calculation and Reference Tools
GD 13 Scientific Graphing Calculator
The GD 13 Scientific Graphing Calculator acts as the backbone of the Grip Dials ecosystem. It allows quick calculations, unit conversions, curve visualization, and mathematical relationships commonly used in suspension tuning and vehicle setup.
Instead of jumping between spreadsheets, phone apps, and notes, the GD 13 keeps everything in one consistent interface.

Alignment and Steering Geometry Visualizers
Ackermann and Toe Visualizer Tool
Ackermann geometry directly affects turn in behavior, mid corner stability, and steering feel. The Ackermann and Toe Visualizer shows how changes in steering angle alter wheel paths and toe relationships.
This tool is especially valuable for drift cars, custom knuckles, and angle kits where traditional assumptions break down.

Camber Angle Calculator
Camber is one of the most misunderstood alignment settings. The Camber Angle Calculator converts ride height changes, strut movement, and geometry into clear camber values you can actually measure and repeat.
This removes guesswork from alignment changes and helps prevent chasing symptoms instead of causes.

Caster Tool
Caster influences steering weight, self centering behavior, camber gain while turning, and high speed stability. The Grip Dials Caster Tool allows you to visualize how caster changes affect steering axis behavior rather than relying on vague rules of thumb.
Suspension Geometry and Chassis Dynamics
Roll Center Tool
Roll center height influences how a car transfers weight laterally and how the suspension reacts under cornering load. The Roll Center Tool visualizes front and rear roll centers so changes in arms, ride height, or pickup points can be understood before parts are cut or welded.
Motion Ratio Visualizer Tool
Motion ratio defines how much the wheel moves relative to the spring and damper. This tool makes it easy to see why spring rates on paper rarely match real world wheel rates.
It is critical when designing custom suspension, relocating shocks, or choosing proper spring rates.

Suspension Frequency Visualizer
Suspension frequency determines how a car responds to bumps, transitions, and weight transfer. This visualizer connects spring rate, corner weight, and motion ratio into a frequency based view that reflects how the car actually behaves.

Anti Squat and Anti Dive Visualizer
Anti squat and anti dive geometry shape how a car reacts under acceleration and braking. This tool visualizes suspension link angles and forces so traction and stability changes can be predicted instead of discovered the hard way.

Tires Wheels and Drivetrain Calculators
Tire and Wheel Fitment Visualizer
Fitment is not just about looks. The Tire and Wheel Fitment Visualizer helps determine clearance, poke, scrub radius effects, and suspension interference before mounting expensive wheels.

Gear Ratio Calculator
Gear ratios determine acceleration, top speed, and engine operating range. The Gear Ratio Calculator shows how transmission ratios, final drive, and tire size interact so gearing can be optimized for track layout or driving style.
SIM Racing Specific Tools
Field of View Calculator
Proper field of view improves depth perception, braking accuracy, and consistency in sim racing. The FOV Calculator removes guesswork by calculating correct values based on screen size and viewing distance.
Fuel Calculator for SIM Racing
Fuel strategy affects lap times and race results. This calculator estimates fuel consumption so pit strategies can be planned instead of improvised.

Utility Tools
Percentage Calculator Tool
Sometimes the simplest tools are the most used. The Percentage Calculator quickly handles bias changes, setup deltas, and comparative adjustments during testing and tuning.

Why GripDial Matters
GripDial is not about replacing driver feel or experience. It is about giving drivers, builders, and engineers the clarity needed to make better decisions faster.
Instead of guessing why a car behaves a certain way, these tools show the underlying geometry and physics in a way that is understandable, repeatable, and actionable.
Whether the goal is drifting, grip racing, engineering, or sim racing, GripDial provides a common language between theory and reality.
