Practical notes about vehicle visualisation, materials, wheels and suspension from the person building 3DTUNNERS. Each guide separates what the browser can help you explore from the measurements and professional checks a real car still needs.
Wheel fitment is a relationship between width, diameter, offset, tyres, brakes and suspension—not a single number. This guide explains what to inspect in a visual concept and what still needs to be measured on the real car.
