Wheel Offset / Backspace / Frontspace Calculator
This tool helps you accurately understand and compare wheel fitment when upgrading or changing wheel sizes.
Whether you're moving to wider wheels, trying to clear suspension components, fitting drag wheels, or fine-tuning stance, the three essential measurements you must understand are offset, backspace, and frontspace.
Fuel Requirement Calculator
Calculate your engine’s fuel requirements based on horsepower, fuel type, injector size, pump flow rate, and target duty cycle.
This tool determines the fuel volume your setup needs and helps you size injectors or fuel pumps correctly for gasoline, E85, or methanol. Perfect for planning upgrades, ensuring adequate fuel delivery, and avoiding horsepower limitations caused by fuel system bottlenecks.
